Border of Ushak carpet, 17th century

The motif is called "Lotto", a striking design of stylized vegetal arabesques in yellow on a red ground are often called "Lotto" carpets after a famous altarpiece by Italian Renaissance painter Lorenzo Lotto that depicts a similar carpet.

I took the last text from an Metropolitan Museum site, that exhibits a border thought to derive from a rectilinear form of Arabic script known as kufic, this type of interlaced border is characteristic of many early Turkish carpets. The Lotto I show has a border showing "bulutlu" (cloud's) motif, deriving from Chinese sources, mainly porcelain.
