Aegaeus is Greek in Origin.

Aegaeus is the Latinized form of Ancient Greek Aigaios (Αἰγαῖος), an epithet meaning 'Aegean' or 'of Aigai,' and by extension 'of the sea.' In Greek cult and poetry it is especially attached to Poseidon (Poseidon Aegaeus), evoking the god’s dominion over the Aegean waters. The underlying root is debated: some relate it to place-names Aigai/Aegae found across the Greek world; others connect it to the Aegean Sea itself, yielding a general sense of sea-born or sea-linked.

Classical usage overlaps with Aegeus/Aigeus (Αἰγεύς), the mythic king of Athens and father of Theseus, whose name is sometimes confused with or rendered as Aegaeus in Latin sources. Documented variants include Aigaios, Aegeus, Aigeus, and the literary Egeus; the feminine forms Aegaea/Aigea also occur. Modern usage is rare, resurfacing mainly in Renaissance and 19th-century neoclassical revivals and in contemporary scholarly or poetic contexts.
