creates—esp. the truss). In the first mode, each repeating geometric form has a built-in symbolism ascribed to it. For example, the square, with its four equilateral sides, is symbolic of the equally important elements of nature: earth, air, fire and water. Without any one of the four, the physical world, represented by a circle that inscribes the square, would collapse upon itself and cease to exist. The second mode is based upon the flowing nature of plant forms. This mode recalls the feminine nature of life giving. In addition, upon inspection of the many examples of Arabesque art, some would argue that there is in fact a third mode, the mode of Islamic calligraphy. Instead of recalling something related to the 'True Reality' (the reality of the spiritual world), Islam considers calligraphy a visible expression of the highest art of all; the art of the spoken word (the transmittal of thoughts and of history). In Islam, the most important document to be transmitted orally is the Qur'an. Proverbs and complete passages from the Qur'an can be seen today in Arabesque art. The coming together of these three forms creates the Arabesque, and this is a reflection of unity arising from diversity; a basic tenet of Islam. The arabesque may be equally thought of as both art and science. The artwork is at the same time mathematically precise, aesthetically pleasing, and symbolic. Due to this duality of creation, the artistic part of this equation may be further subdivided into both secular and religious artwork. However, for many Muslims there is no distinction; all forms of art, the natural world, mathematics and science are seen to be creations of God and therefore reflections of the same thing: God's will expressed through his creation. In other words, man can discover the geometric forms that constitute the arabesque, but these forms always existed before as part of God's creation, as shown in this picture. There is great similarity between arabesque artwork from very different geographic regions. In fact, the similarities are so pronounced that it is sometimes difficult for experts to tell where a given style of arabesque comes from. The reason for this is that the science and mathematics that are used to construct Arabesque artwork are universal. Therefore, for most Muslims, the best artwork that can be created by man for use in the Mosque is artwork that displays the underlying order
