The flame palmette is a motif in decorative art which, in its most characteristic expression, resembles the fan-shaped leaves of a palm tree.
From the 4th century BCE however, the end of the leaves tend to turn in, forming what is called the "flame palmette" design.
[1] The first appearance of flame palmettes seem to occur with the stand-alone floral akroteria of the Parthenon (447–432 BCE),[2] and slightly later at the Temple of Athena Nike.
The flame palmette design that was adopted in Hellenistic architecture and became very popular on a wide geographical scale, especially following the conquests of Alexander the Great.
In the Greco-Bactrian city of Ai-Khanoum, founded circa 280 BCE, the antefixae display a flame palmette design, as do floral mosaics.
