The Arabians used geometry, although they added little to its advancement. Geometry had reached at this period an advanced stage of progress in the problems of Euclid. It was to the honor of the Arabians that they were the first of any of the Western peoples to translate Euclid and use it, for it was not until the sixteenth century that it was freely translated into the modern languages.

But in trigonometry the Arabians, by the introduction of the use of the sine, or half-chord, of the double arc in the place of the arc itself, made great advancement, especially in the calculations of surveying and astronomy. In the universities and colleges of Spain under Arabian dominion we find, then, that students had an opportunity of mastering nearly all of the useful elementary mathematics. Great attention was paid to the study of astronomy. Here, as before, they used the Greek knowledge, but they advanced the study of the science greatly by the introduction of instruments, such as those for measuring time by the movement of the pendulum and the measurement of the heavenly bodies by the astrolabe.

Likewise they employed the word "azimuth" and many other terms which show a more definite knowledge of the relation of the heavenly bodies.

They were enabled, also, to {312} measure approximately a degree of lat.i.tude. They knew that the earth was of spheroid form. But we find astrology accompanying all this knowledge of astronomy. While the exact knowledge of the heavenly bodies had been developed to a certain degree, the science of star influence, or astrology, was cultivated to a still greater extent. Thus they sought to show the control of mind forces on earth, and, indeed, of all natural forces by the heavenly bodies. This placed mystical lore in the front rank of their philosophical speculations.

_Geography and History_.--In the study of the earth the Arabians showed themselves to be practical and accurate geographers. They applied their mathematical and astronomical knowledge to the study of the earth, and thus gave an impulse to exploration. While their theories of the origin of the earth were crude and untenable, their practical writings on the subject derived from real knowledge, and the practical instruction in schools by the use of globes and maps, were of immense practical value.

Their history was made up chiefly of the histories of cities and the lives of prominent men. There was no national history of the rise and development of the Arabian kingdom, for historical writing and study were in an undeveloped state.

_Discoveries, Inventions, and Achievements_.--It cannot be successfully claimed that the Arabians exhibited very much originality in the advancement of the civilized arts, yet they had the ability to take what they found elsewhere developed by other scholars, improve upon it, and apply it to the practical affairs of life. Thus, although the Chinese discovered gunpowder over 3,000 years ago, it remained for the Arabs to bring it into use in the siege of Mecca in the year 690, and introduce it into Spain some years later. The Persians called it Chinese salt, the Arabians Indian snow, indicating that it might have originated in different countries. The Arab-Moors used it in their wars with the Christians as early as the middle of the thirteenth century. They excelled also in making paper from flax, or cotton, which was probably an imitation {313} of the paper made by the Chinese from silk. We find also that the Arabs had learned to print from movable type, and the introduction of paper made the printing-press possible. Linen paper made from old clothes was said to be in use as early as 1106.

Without doubt the Arab-Moors introduced into Spain the use of the magnet in connection with the mariner's compa.s.s. But owing to the fact that it was not needed in the short voyages along the coast of the Mediterranean, it did not come into a large use until the great voyages on the ocean, in the beginning of the fourteenth century. Yet the invention of the mariner's compa.s.s, so frequently attributed to Flavio Giorgio, may be as well attributed to the Arab-Moors.

Knives and swords of superior make, leather, silk, and gla.s.s, as well as large collections of delicate jewelry, show marked advancement in Arabian industrial art and mechanical skill.

One of the achievements of the Arab-Moors in Spain was the introduction of agriculture, and its advancement to an important position among the industries by means of irrigation. The great, fertile valleys of Spain were thus, through agricultural skill, made "to blossom as the rose."

Seeds were imported from different parts of the world, and much attention was given to the culture of all plants which could be readily raised in this country. Rice and cotton and sugar-cane were cultivated through the process of irrigation. Thus Spain was indebted to the Arab-Moors not only for the introduction of industrial arts and skilled mechanics, but the establishment of agriculture on a firm foundation.

_Language and Literature_.--The language of the Arabians is said to be peculiarly rich in synonyms. For instance, it is said there are 1,000 expressions for the word "camel," and the same number for the word "sword," while there are 4,000 for the word "misfortune." Very few remnants of the Arabic remain in the modern European languages. Quite a number of words in the Spanish language, fewer in English and in {314} other modern languages, are the only remnants of the use of this highly developed Arabian speech. It represents the southern branch of the Semitic language, and is closely related to the Hebrew and the Aramaic. The unity and compactness of the language are very much in evidence. Coming little in contact with other languages, it remained somewhat exclusive, and retained its original form.

When it came into Spain the Arabic language reigned almost supreme, on account of the special domination of Arabic influences. Far in the north of Spain, however, among the Christians who had adopted the Low Latin, was the formation of the Spanish language. The hatred of the Spaniards for the Arabs led these people to refuse to use the language of the conquerors. Nevertheless, the Arabic had some influence in the formation of the Spanish language. The isolated geographic terms, and especial names of things, as well as idioms of speech, show still that the Arabian influence may be traced in the Spanish language.

In literature the Arabians had a marked development. The Arabian poetry, though light in its character, became prominent. There were among these Arabians in Spain ardent and ready writers, with fertile fancy and lively perception, who recited their songs to eager listeners. The poet became a universal teacher. He went about from place to place singing his songs, and the troubadours of the south of France received in later years much of their impulse indirectly from the Arabic poets. While the poetry was not of a high order, it was wide-reaching in its influence, and extended in later days to Italy, Sicily, and southern France, and had a quickening influence in the development of the light songs of the troubadours. The influence of this lighter literature through Italy, Sicily, and southern France on the literature of Europe and of England in later periods is well marked by the historians. In the great schools rhetoric and grammar were also taught to a considerable extent. In the universities these formed one of the great branches of special culture. We find, then, on the linguistic {315} side that the Arabians accomplished a great deal in the advancement of the language and literature of Europe.

_Art and Architecture_.--Perhaps the Arabians in Spain are known more by their architecture than any other phase of their culture. Not that there was anything especially original in it, except in the combination which they made of the architecture of other nations. In the building of their great mosques, like that of Cordova and of the Alhambra, they perpetuated the magnificence and splendor of the East. Even the actual materials with which they constructed these magnificent buildings were obtained from Greece and the Orient, and placed in their positions in a new combination. The great original feature of the Mooresque architecture is found in the famous horseshoe arch, which was used so extensively in their mosques and palaces. It represented the Roman arch, slightly bent into the form of a horseshoe. Yet from architectural strength it must be considered that the real support resting on the pillar was merely the half-circle of the Roman arch, while the horseshoe was a continuation for ornamental purposes.

The Arab-Moors were forbidden the use of sculpture, which they never practised, and hence the artistic features were limited to architectural and art decorations. Many of the interior decorations of the walls of these great buildings show advanced skill. Upon the whole, their buildings are remarkable mainly in the perpetuation of Oriental architecture rather than in the development of any originality except in skill of decoration and combination.

_The Government of the Arab-Moors Was Peculiarly Centralized_.--The caliph was at the head as an absolute monarch. He appointed viceroys in the different provinces for their control. The only thing that limited the actual power of the caliph was the fact that he was a theocratic governor. Otherwise he was supreme in power. There was no const.i.tutional government, and, indeed, but little precedent in law.

The government depended somewhat upon the whims and caprices {316} of a single individual. It was said that in the beginning the caliph was elected by the people, but in a later period the office became hereditary. It is true the caliph, who was called the "vicar of G.o.d,"

or "the shadow of G.o.d," had his various ministers appointed from the wise men to carry out his will. Yet, such was the power of the people what when in Spain they were displeased with the rulings of the judges, they would pelt the officers or storm the palace, thus in a way limiting the power of these absolute rulers.

The government, however, was in a precarious condition. There could be nothing permanent under such a regime, for permanency of government is necessary to the advancement of civilization. The government was non-progressive. It allowed no freedom of the people and gave no incentive to advancement, and it was a detriment many times to the progressive spirit. Closely connected with a religion which in itself was non-progressive, we find limitations set upon the advancement of the civilization of the Arab-Moors in Spain.

_Arabian Civilization Soon Reached Its Limits_.--One views with wonder and astonishment the brilliant achievements of the Arabian civilization, extending from the Tagus to the Indus. But brilliant as it was, one is impressed at every turn with the instability of the civilization and with its peculiar limitations. It reached its culmination long before the Christian conquest. What the Arabians have given to the European world was formulated rapidly and given quickly, and the results were left to be used by a more slowly developing people, who rested their civilization upon a permanent basis. Much stress has been laid by Mr. Draper and others upon the great civilization of the Arabians, comparing it favorably with the civilization of Christian Europe. But it must be remembered that the Arab-Moors, especially in Spain, had come so directly in contact with Oriental nations that they were enabled to borrow and utilize for a time the elements of civilization advanced by these more mature peoples. However, built as it was upon borrowed materials, the structure once completed, {317} there was no opportunity for growth or original development. It reached its culmination, and would have progressed no further in Spain, even had not the Christians under Ferdinand and Isabella conquered the Arab-Moors and eventually overcome and destroyed their civilization. In this conquest, in which the two leading faiths of the Western world were fighting for supremacy, doubtless the Christian world could not fully appreciate what the Arab-Moors accomplished, nor estimate their value to the economic system of Spain.

Subsequent facts of history show that, the Christian religion once having a dominant power in Spain, the church became less liberal in its views and its rule than that exhibited by the government of the Arab-Moors. Admitting that the spirit of liberty had burst forth in old Asturias, a seat of Nordic culture, it soon became obscure in the arbitrary domination of monarchy, and of the church through the instrumentality of Torquemada and the Inquisition. Nevertheless, the civilization of the Arab-Moors cannot be pictured as an ideal one, because it was lacking in the fundamentals of continuous progress.

Knowledge had not yet become widely disseminated, nor truth free enough to arouse vigorous qualities of life which make for permanency in civilization. With all of its borrowed art and learning and its adaptation to new conditions, still the civilization was sufficiently non-progressive to be unsuited to carry the burden of the development of the human race. Nevertheless, in the contemplation of human progress, the Arab-Moors of Spain are deserving of attention because of their universities and their studies, which influenced other parts of mediaeval Europe at a time when they were breaking away from scholastic philosophy and a.s.suming a scientific att.i.tude of mind.

CHAPTER XX

THE CRUSADES STIR THE EUROPEAN MIND

_What Brought About the Crusades_.--We have learned from the former chapters that the Arabs had spread their empire from the Euphrates to the Strait of Gibraltar, and that the Christian and Mohammedan religions had compa.s.sed and absorbed the entire religious life over this whole territory. As Christianity had become the great reforming religion of the western part of Europe, so Mohammedanism had become the reforming religion of Asia. The latter was more exacting in its demands and more absolute in its sway than the former, spreading its doctrines mainly by force, while the former sought more to extend its doctrine by a leavening process. Nevertheless, when the two came in contact, a fierce struggle for supremacy ensued. The meteorlike rise of Mohammedanism had created consternation and alarm in the Christian world as early as the eighth century. There sprang up not only fear of Islamism, but a hatred of its followers.

After the Arabian Empire had become fully established, there arose to the northeast of Bagdad, the Moslem capital, a number of Turkish tribes that were among the more recent converts to Mohammedanism. Apparently they took the Mohammedan religion as embodied in the Koran literally and fanatically, and, considering nothing beyond these, sought to propagate the doctrine through conquest by sword. They are frequently known as Seljuks. It is to the credit of the Arabs, whether in Mesopotamia, Africa, or Spain, that their minds reached beyond the Koran into the wider ranges of knowledge, a fact which tempered their fanatical zeal, but the Seljuk Turks swept forward with their armies until they conquered the Byzantine Empire of the East, the last branch of the great Roman Empire. They had also conquered Jerusalem and {320} taken possession of the holy sepulchre, to which pilgrimages of Christians were made annually, and aroused the righteous indignation of the Christians of the Western world. The ostensible purpose of the crusades was to free Palestine, the oppressed Christians, and the holy sepulchre from the domination of the Turks.

It must be remembered that the period of the Middle Ages was represented by fancies and theories and an evanescent idealism which controlled the movements of the people to a large extent. Born of religious sentiment, there dwelt in the minds of Christian people a reverence for the land of the birth of Christ, to which pilgrims pa.s.sed every year to show their adoration for the Saviour and patriotism for the land of his birth. These pilgrims were interfered with by the Mohammedans and especially by the Seljuk Turks.

The Turks in their blind zeal for Mohammedanism could see nothing in the Christian belief worthy of respect or even civil treatment. The persecution of Christians awakened the sympathy of all Europe and filled the minds of people with resentment against the occupation of Jerusalem by the Turks. This is one of the earliest indications of the development of religious toleration, which heralded the development of a feeling that people should worship whom they pleased unmolested, though it was like a voice crying in the wilderness, for many centuries pa.s.sed before religious toleration could be acknowledged.

There were other considerations which made occasion for the crusades.

Gregory VII preached a crusade to protect Constantinople and unify the church under one head. But trouble with Henry IV of Germany caused him to abandon the enterprise. There still dwelt in the minds of the people an ideal monarchy, as represented by the Roman Empire. It was considered the type of all good government, the one expression of the unity of all people. Many dreamed of the return of this empire to its full temporal sway. It was a species of idealism which lived on through the Middle Ages long after the {321} Western Empire had pa.s.sed into virtual decay. In connection with this idea of a universal empire controlling the whole world was the idea of a universal religion which should unite all religious bodies under one common organization. The centre of this organization was to be the papal authority at Rome.

There dwelt then in the minds of all ecclesiastics this common desire for the unity of all religious people in one body regardless of national boundaries. And it must be said that these two ideas had much to do with giving Europe unity of thought and sentiment. Disintegrated as it was, deflected and disturbed by a hundred forces, thoughts of a common religion and of universal empire nevertheless had much to do to harmonize and unify the people of Europe. Hence, it was when Urban II, who had inherited all of the great religious improvements inst.i.tuted by Gregory VII, preached a crusade to protect Constantinople, on the one hand, and to deliver Jerusalem, on the other, and made enthusiastic inflammatory speeches, that Europe awoke like an electric flash. Peter the Hermit, on the occasion of the first crusade, was employed to travel throughout Europe to arouse enthusiasm in the minds of the people.

The crusades so suddenly inaugurated extended over a period of nearly two hundred years, in which all Europe was in a restless condition.

The feudal life which had settled down and crystallized all forms of human society throughout Europe had failed to give that variety and excitement which it entertained in former days. Thousands of knights in every nation were longing for the battle-field. Many who thought life at home not worth living, and other thousands of people seeking opportunities for change, sought diversion abroad. All Europe was ready to exclaim "G.o.d wills it!" and "On to Jerusalem!" to defend the Holy City against the Turk.

_Specific Causes of the Crusades_.--If we examine more specifically into the real causes of the crusades we shall find, as Mr. Guizot has said, that there were two causes, the one moral, the other social. The moral cause is represented in the {322} desire to relieve suffering humanity and fight against the injustice of the Turks. Both the Mohammedan and the Christian, the two most modern of all great religions, were placed upon a moral basis. Morality was one of the chief phases of both religions; yet they had different conceptions of morality, and no toleration for each other. Although prior to the Turkish invasion the Mohammedans, through policy, had tolerated the visitations of the Christians, the two cla.s.ses of believers had never gained much respect for each other, and after the Turkish invasion the enmity between them became intense. It was the struggle of these two systems of moral order that was the great occasion and one of the causes of the crusades.

The social cause, however, was that already referred to--the desire of individuals for a change from the monotony which had settled down over Europe under the feudal regime. It was the mind of man, the enthusiasm of the individual, over-leaping the narrow bounds of his surroundings, and looking for fields of exploitation and new opportunities for action. The social cause represents, then, the spontaneous outburst of long-pent-up desires, a return to the freedom of earlier years, when wandering and plundering were among the chief occupations of the Teutonic tribes. To state the causes more specifically, perhaps it may be said that the ambition of temporal and spiritual princes and the feudal aristocracy for power, the general poverty of the community on account of overpopulation leading the mult.i.tudes to seek relief through change, and a distinct pa.s.sion for pilgrimages were influential in precipitating this movement.

_Unification of Ideals and the Breaking of Feudalism_.--It is to be observed that the herald of the crusades thrilled all Europe, and that, on the basis of ideals of empire and church, there were a common sentiment or feeling and a common ground for action. All Europe soon placed itself on a common plane in the interest of a common cause. At first it would seem that this universal movement would have tended to {323} develop a unity of Western nations. To the extent of breaking down formal custom, destroying the sterner aspects of feudalism, and levelling the barriers of cla.s.ses, it was a unifier of European thought and life.

But a more careful consideration reveals the fact that although all groups and cla.s.ses of people ranged themselves on one side of the great and common cause, the effect was not merely to break down feudalism but, in addition, to build up nationality. There was a tendency toward national unity. The crusades in the latter part of the period became national affairs, rather than universal or European affairs, even though the old spirit of feudalism, whereby each individual followed by his own group of retainers sought his own power and prestige, still remained. The expansion of this spirit to larger groups invoked the national spirit and national life. While, in the beginning, the papacy and the church were all-powerful in their controlling influence on the crusades, in the later period we find different nationalities, especially England, France, and Germany, struggling for predominance, the French nation being more strongly represented than any other.

Among the important results of the crusades, then, were the breaking down of feudalism and the building up of national life. The causes of this result are evident. Many of the n.o.bility were slain in battle or perished through famine and suffering, or else had taken up their abode under the new government that had been established at Jerusalem. This left a larger sway to those who were at home in the management of the affairs of the territory. Moreover, in the later period, the stronger national lines had been developed, which caused the subordination of the weaker feudal lords to the more powerful. Many, too, of the strong feudal lords had lost their wealth, as well as their position, in carrying on the expenses of the crusades. There was, consequently, the beginning of the remaking of all Europe upon a national basis. First, the enlarged ideas of life broke the bounds of feudalism; second, the failure to unite the nations in the common sentiment of a Western {324} Empire had left the political forces to cl.u.s.ter around new nationalities which sprang up in different sections of Europe.

_The Development of Monarchy_.--The result of this centralization was to develop monarchy, an inst.i.tution which became universal in the process of the development of government in Europe. It became the essential form of government and the type of national unity. Through no other known process of the time could the chaotic state of the feudal regime be reduced to a system. Const.i.tutional liberty could not have survived under these conditions. The monarchy was not only a permanent form of government, but it was possessed of great flexibility, and could adapt itself to almost any conditions of the social life. While it may, primarily, have rested on force and the predominance of power of certain individuals, in a secondary sense it represented not only the unity of the race from which it had gained great strength, but also the moral power of the tribe, as the expression of their will and sentiments of justice and righteousness.

It is true that it drew a sharp line between the governing and the governed; it made the one all-powerful and the other all-subordinate; yet in many instances the one man represented the collective will of the people, and through him and his administration centred the wisdom of a nation.

Among the Teutonic peoples, too, there was something more than sentiment in this form of government. It was an old custom that the barbarian monarch was elected by the people and represented them; and whether he came through hereditary rank, from choice of n.o.bles, or from the election of the people, this idea of monarchy was never lost sight of in Europe in the earliest stages of existence, and it was perverted to a great extent only by the Louis's of France and the Stuarts of England, in the modern era. Monarchy, then, as an inst.i.tution, was advanced by the crusades; for a national life was developed and centralization took place, the king expressed the unity of it all, and so everywhere throughout Europe it became the universal type.
