Said to be from Fayum, Medinet el-Fayum (Krokodilopolis-Arsinoe), 2nd century BCE.

On several finds from the Fayoum of the Late Period Banebdjedet is depicted as intercessor between worshiping persons and Sobek-Ra. Also, in Roman times, Banebdjedet was very often depicted as this type of ram.
Chances are good, that this is actually Banebdjedet. As Harpocrate’s father the connection to the lotus is even stronger.
