Rome's diplomatic agreement with her neighbours of Latium confirmed the Latin league and brought the cult of Diana from Aricia to the Aventine. and established on the Aventine in the "commune Latinorum Dianae templum": At about the same time, the temple of Jupiter Latiaris was built on the Alban mount, its stylistic resemblance to the new Capitoline temple pointing to Rome's inclusive hegemony. Rome's affinity to the Latins allowed two Latin cults within the pomoerium: and the cult to Hercules at the ara maxima in the Forum Boarium was established through commercial connections with Tibur. and the Tusculan cult of Castor as the patron of cavalry found a home close to the Forum Romanum: Juno Sospita and Juno Regina were brought from Italy, and Fortuna Primigenia from Praeneste. In 217, Venus was brought from Sicily and installed in a temple on the Capitoline hill.
