According to the Greek historian Diodorus Siculus, Sorrento was founded by Liparus, son of Ausonus, who was king of the Ausoni and the son of Ulysses and Circe. The ancient city was probably connected to the Ausoni tribe, one of the most ancient ethnic groups in the area. In the pre-Roman age, Sorrento was influenced by the Greek civilization: this can be seen in its plant and in the presence of the "Athenaion", a great sanctuary, also, according to the legend, founded by Ulysses and originally devoted to the cult of the Sirens, hence Sorrento's name.
