What is in this image? Describe it as if you were explaining it to someone from the 15th century.

Behold, this image presents a composition much like the esteemed geometric tiles seen in the grand palaces and churches, though it carries no color but the strokes of black upon a pure white. You gaze upon a multitude of angular shapes, which can be likened to an arrangement of shields or perhaps patterns upon a stonemason''s floor, each bearing within it a series of ever-smaller arrows nested one within another. These arrows, reminiscent of the fletching used by archers, are directed inward, towards the heart of each figure, creating a sense of infinite recurrence or perhaps guiding one''s eye towards a center unseen. Nay, there is no gold or azure tint, only the stark contrast of these forms as if etched with coal upon parchment by some inspired scholar''s hand, inviting contemplation upon their order and repetition.
