Hersilia was the wife of Romulus, the founder and first King of Rome in Rome's founding myths. She is described as such in both Livy and Plutarch; but in Dionysius, Macrobius, and another tradition recorded by Plutarch, she was instead the wife of Hostus Hostilius, a Roman champion at the time of Romulus. This would make her the grandmother of Tullus Hostilius, the third king of Rome.
The principal source of traditions relating to Hersilia is Livy, I.xi:
Just like her husband (who became the god Quirinus), she was deified after her death as Hora, as recounted in Ovid, Metamorphoses 14.829–851:
The Hersilia (or long-spinnered bark spiders) are a genus in the Hersiliidae family. They are sometimes known as two-tailed spiders, due to their greatly enlarged spinnerets.
Males grow up to 8 mm long, and females up to 10 mm. They can be found on tree trunks in gardens or jungle fringes in Africa, Asia and Australasia.
The revisions by Baehr & Baehr and Rheims & Brescovit revealed 26 species in southeast Asia.
