Name

Erinome was named in October 2002 after the mythological Erinoma, a Cypriot woman said by the discovery group to be a "daughter of Celes, compelled by Venus to fall in love with Jupiter." In the surviving myths however, it is actually

) makes fall in love with Erinoma, in order to ruin her. The final -a vowel of the name was changed to -e to accord with IAU naming conventions for retrograde moons. The story is only known in Latin, and manuscripts have the name as ''Erinoma'', ''Erinona'' and ''Erittoma''. The original Greek name, and thus the stressed syllable in Latin, is unknown. It might be a late corruption of

Eurynome Eurynomê (; Ancient Greek: Εὐρυνόμη, from , ''eurys'', "broad" and , ''nomos'', "pasture" or "law") is a name that refers to the following characters in Greek mythology: * Eurynome, pre-Olympian queen and wife of Ophion * Eurynome (Oce ...

, in which case the stress would be on the third syllable (?). Since there is no moon named 'Eurynome' , this would not be ambiguous.
