Palmer thinks she is to be identified with Juno Populona of later inscriptions, a political and military poliadic (guardian) deity who had in fact a place in the Capitoline temple and was intended to represent the "Regina" of the king. The date of her introduction, though ancient, would be uncertain; she should perhaps be identified with Hera Basilea or as the queen of Jupiter Rex. The actual epithet Regina could though come from Veii. At Rome this epithet may have been applied to a Juno other than that of the temple on the Aventine built to lodge the evocated Veian Juno as the rex sacrorum and his wife-queen were to offer a monthly sacrifice to Juno in the Regia. This might imply that the prerepublican Juno was royal.
