It is equally true that from about the middle of the 8th century a prohibition had been formally stated, and thenceforth it would be a standard feature of Islamic thought, even though the form in which it is expressed has varied from absolute to partial and even though it has never been totally followed. The justification for the prohibition tended to be that any representation of a living thing was an act of competition with God, for he alone can create something that is alive.
It is striking that this theological explanation reflects the state of the arts in the Christian world at the time of the Muslim conquest—a period of iconoclastic controversy. It may thus be suggested that Islam developed an attitude toward images as it came into contact with other cultures and that its attitude was negative because the arts of the time appeared to lead easily to dreaded idolatry. While it is only by the middle of the 8th century that there is actual proof of the existence of a Muslim doctrine, it is likely that, more or less intuitively, the Muslims felt a certain reluctance toward representations from the very beginning. For all monuments of religious art are devoid of any representations; even a number of attempts at representational symbolism in the official art of coinage were soon abandoned.
This rapid crystallization of Islamic attitudes toward images has considerable significance. For practical purposes, representations are not found in religious art, although matters are quite different in secular art. Instead there occurred very soon a replacement of imagery with calligraphy and the concomitant transformation of calligraphy into a major artistic medium. Furthermore, the world of Islam tended to seek means of representing the holy other than by images of men, and one of the main problems of interpretation of Islamic art is that of the degree of means it achieved in this search.
But there is a deeper aspect to this rejection of holy images. Although the generally Semitic or specifically Jewish sources that have been given to Islamic iconoclasms have probably been exaggerated, the reluctance imposed by the circumstances of the 7th century transformed into a major key of artistic creativity the magical fear of visual imagery that exists in all cultures but that is usually relegated to a secondary level. This uniqueness is certainly one of the main causes of the abstract tendencies that are among the great glories of the tradition. Even when a major art of painting did develop, it remained always somehow secondary to the mainstream of the culture’s development.
Both in the case of the religious building and in that of the representations, therefore, it was the contact with preIslamic cultures in Muslim-conquered areas that compelled Islam to transform its practical and unique needs into monuments and to seek within itself for intellectual and theological justifications for its own instincts. The great strength of early Islam was that it possessed within itself the ideological means to put together a visual expression of its own, even though it did not develop at the very beginning a need for such an expression.
