Quirinus. An early Roman god, claimed by the ancients to have been Sabine in origin, and from the third century BC identified with the deified Romulus.
[Plutarch, Romulus 29; Ovid, Fasti 2.475-80.]

Hercules. The Roman name for Heracles. Hercules shared the mythology of his Greek counterpart, though with various minor Roman additions, the best-known being that of his destruction of the fire-breathing monster Cacus.

Anna and Anna Perenna. A Roman goddess about whom Ovid tells three stories (Fasti 3.523-696), one of which identifies Anna with an old woman who provided food for the Roman plebeians, during a period of political troubles, when they left Rome and went to live for a while on the Sacred Mountain. He also identifies her with Dido's sister Anna, who supported Dido in her passion and grief over Aeneas and mourned deeply for her on her suicide. Anna fled from Carthage, eventually arriving in Latium where Aeneas was now ruling. Recognising her, he welcomed her and wept over Dido's sad death, then took Anna into his household. Unfortunately his wife Lavinia was jealous of this link with her husband's past, and Anna, warned in a dream, fled from the palace at dead of night. In the darkness she was swept away by the River Numicius. The next day they all searched for her, following her tracks to the river-bank, and there she appeared to them, announcing that she was now a nymph with the name Anna Perenna, signifying eternity. They spent the day in celebration, and this was the origin of the goddess' annual festival.
      In old age Anna was persuaded by Mars to act as his go-between in his pursuit of Minerva. Anna knew that the virgin goddess would never succumb, but she fed Mars on false hopes and eventually herself took Minerva's place in an assignation with the god by night. Only when he lifted her veil did he recognise her, and the angry words that he uttered were said to be the origin of the ribald songs sung at Anna's festival.
