Etruscan goddess, considered by the Romans to be identical to Juno.
Uni was worshipped in many Etrucan cities, often together with the sky god Tinia and the goddes Menrva (corresponding to the Roman Capitoline Triad of Jupiter, Juno and Minerva). She is considered the mother of the demigod Hercle (corresponding to Hercules).
Legend has it that the Roman priests convinced Uni to "defect" to Rome during the siege (in 392 BCE) of the Etruscan city of Veii. The Romans conquered the city and moved the statue of Uni to Rome, where she was placed in a temple of her own, on the Aventine hill.
