That the whole of the area which the temple of Jupiter was to occupy might be wholly devoted to that deity, he decided to deconsecrate the fanes and chapels, some of which had been originally vowed by King Tatius at the crisis of his battle with Romulus, and subsequently consecrated and inaugurated.
Tradition records that at the commencement of this work the gods sent a divine intimation of the future vastness of the empire, for whilst the omens were favourable for the deconsecration of all the other shrines, they were unfavourable for that of the fane of Terminus.
This was interpreted to mean that as the abode of Terminus was not moved and he alone of all the deities was not called forth from his consecrated borders, so all would be firm and immovable in the future empire.
