The word troia in italian may describe a female animal – a sow – or a human sex worker: troia is a derogatory term for a female prostitute. Capitalize the word, however, and it becomes, instead, the illustrious ancient city of Troy, Rome's urban ancestor. Likewise, the Latin word lupa has two meanings: It indicates, metaphorically, a prostitute; yet lupa is also the she-wolf who suckled Romulus and Remus. It is from the fusion of two separate legends embedded in each of these two ambiguous, grammatically feminine words – troia and lupa – that the story of Rome's birth derives: the fifth-century bce Greek legend, which attributed Rome's founding to the Trojan hero Aeneas around the twelfth century bce, and the later indigenous legend of the she-wolf, dating from 300 bce and according to which a native founder and his twin brother were saved by a local beast four and a half centuries earlier. By the first century bce, the two legends had blended harmoniously, making Romulus a descendant of Aeneas as a compromise and with a few hundred years elapsing between the births of the two alleged (and, until then, competing) founders. However crucial Aeneas's arrival on Italian soil, though, and no matter how necessary Romulus's building of Rome's first wall and his murder of his brother, it is the scene of the she-wolf nursing two baby boys – and the narrative that this image tells – that remains the most visible and most frequently represented moment in the story of Rome's foundation.
