In Greek mythology, Aethusa (Ancient Greek: Αἵθουσα) was a daughter of Poseidon and the Pleiad Alcyone, daughter of Atlas.
[1][2][3] She was loved by Apollo and bore to him Eleuther[4] and Linus.
[6] The word aethusa was used as an epithet for a portico that was open to the sun above.
[7] According to Pliny's Naturalis Historia, Aethusa is also the eponym of the Italian island which is now called Linosa.
