It is an ancient Greek symbol, called Greek Key, found all over ancient temples and pottery, even as far back as 3000 years ago. See:

The following link will take you to a photo of a plate with the symbol painted just below the belly of the creature on the plate (7th century BC).

This symbol is oftentimes found connected, in continous friezes, running along under the eaves of temple buidlings.
