As Minerva Medica she is the patroness of physicians. Minerva is believed to be the inventor of numbers and musical instruments. She is thought to be of Etruscan origin, as the goddess Menrva or Menerva. Later she was equated with the Greek Athena and as such is also sometimes associated as a Goddess of war.
She is the daughter of Jupiter. In the temple on the Capitoline Hill she was worshipped together with Jupiter and Juno, with whom she formed a powerful triad of gods. Another temple of her was located on the Aventine Hill. The church of Santa Maria sopra Minerva is built on one of her temples.
