In the relief the personalized north wind is depicted with a beard and long hair while flying. He is wearing a chiton, a cloak (himation) and boots (endromides). In his right hand holds the shell Charonia tritonis. The inscription "ΒΟΡΕΑΣ" above the relief. The other wind deities (Kaikias (NE), Apeliotes (E), Eurus (SE), Notus (S), Lips (SW), Zephyrus (W), and Skiron (NW)) are depicted on either side of Boreas. Each of them holds its own symbol.
