"Io (/ˈaɪ.oʊ/; Ancient Greek: Ἰώ [iːɔ̌ː] was, in Greek mythology, one of the mortal lovers of Zeus. An Argive princess, she was an ancestor of many kings and heroes such as Perseus, Cadmus, Heracles, Minos, Lynceus, Cepheus, and Danaus. The astronomer Simon Marius named a moon of Jupiter after Io in 1614." - (en.wikipedia.org 27.11.2019)
