Bia

In Greek mythology, Bia (; Ancient Greek: Βία ; "force, strength") is the personification of force. According to the preface to Fabulae by Gaius Julius Hyginus, Bia's Roman name was Vis. Family Bia was the daughter of the Titan Pallas and Oceanid Styx, and sister of Nike, Kratos, and Zelus. From Pallas the giant and Styx [were born]: Scylla, Vis (Force) [Bia], Invidia (Jealousy) [Zelos], Potestas (Power) [Kratos], Victoria (Victory) [Nike]. Mythology Bia and her siblings were constant companions of Zeus. They achieved this honour after supporting him in the Titan War along with their mother. Bia is one of the characters named in the Greek tragedy Prometheus Bound, attributed to Aeschylus, where Hephaestus is compelled by the gods to bind Prometheus after he was caught stealing fire and offering the gift to mortals. Although she appears alongside her brother Kratos, she does not speak.
