Uni was the supreme goddess of the Etruscan pantheon and the patron goddess of Perugia. Uni was identified by the Etruscans as their equivalent of Juno in Roman mythology and Hera in Greek mythology.
Uni appears in the Etruscan text on the Pyrgi Tablets as the translation of the Phoenician goddess Astarte. Livy states (Book V, Ab Urbe Condita) that Juno was an Etruscan goddess of the Veientes, who was ceremonially adopted into the Roman pantheon when Veii was sacked in 396BC. This seems to refer to Uni. She also appears on the Liver of Piacenza.
