Philip I Philadelphos Tetradrachm

One interesting fact about Philip I Philadelphos is that he was known for his deep affection for his sister and wife, Laodice Thea. The title "Philadelphos" (ΦΙΛΑΔΕΛΦΟΥ that you can on this tetradrachm) in his name actually means "Sibling-loving". Their close relationship was evident in their coins and inscriptions, which often emphasized their strong familial bond. This practice was not uncommon among Hellenistic rulers, but Philip I Philadelphos and Laodice Thea are particularly well-known for the prominence they gave to their sibling relationship in the art and symbolism of their time.
