So great was Rome's sense of kinship to the Latins that in two cases Latin cults were introduced inside the pomoerium: the worship of Hercules, which came from Tibur in connexion with commerce, was established at the ara maxima in the forum boarium, and the Tusculan cult of Castor as the patron of cavalry found a home close to the forum Romanum: it is a strange irony that both these deities should in reality have been in their origin Greek.
The same spirit continues to show itself in the almost reckless introduction of Greek deities even within the walls of the pomoerium and their ready identification with gods of the old religion, whose cult they in reality superseded.
