The Platonic verses:

Since the principal subject of calligraphy always remained the divine word of God, copying of the Qu’ran gave rise to numerous questions involving geometry, beauty and theology itself. “Should all copies be written in exactly the same way? Should they all have same number of lines? Could words be broken at the end of a line and continue onto the following one? On these points there appears to have been no general consensus at first. Eventually, however, Qu’rans came to be copied out in odd numbers of lines and the splitting up of words was forbidden,” writes historian David James. The structure of these Qu’rans hints at number-mysticism and atomism very similar to ancient Greek philosophers like Euclid and Plato, whose works were also being studied and translated during this period.
