Lore & Background
The hippocampus appears in ancient coinage: coins from Tyre around the 4th century BC show Melqart riding a winged hippocampus, while coins from Byblos depict a hippocampus diving under a galley. A gold hippocamp was discovered in a hoard from Lydia dating to the 6th century BC. In Greek and Roman tradition, Poseidon often drives a sea-chariot drawn by hippocampi, as seen in the Iliad and later in the Argonautica of Gaius Valerius Flaccus, which describes 'two-hooved' hippocampi. The creature also appears in Etruscan tomb paintings and reliefs, sometimes with wings, reflecting a belief in a sea-voyage to the other world.
Reader's Guide
The hippocampus held significance across multiple ancient cultures, serving as a symbol of maritime power and divine connection. In Greek and Roman contexts, it was closely tied to Poseidon (Neptune), appearing in temple sculptures, such as the gilt-bronze and ivory horses at the temple of Poseidon at Corinth, and in mosaics at Roman baths like Aquae Sulis. Its presence in both freshwater and saltwater settings reflects ancient hydrological beliefs that seawater flowed back onto land through caverns. During the Renaissance and later, the hippocampus became a heraldic charge, often used by people and places with maritime associations. In heraldry, the terms 'hippocamp' and 'seahorse' have swapped meanings: the mythological creature is now called a 'sea-horse,' while the real seahorse is termed 'hippocamp.' The creature also appears in modern contexts, such as the Air France logo and the crest of Newcastle United football club. A moon of Neptune discovered in 2013 was named for the hippocampus in 2019.
