There are multiple origins and meanings for the name Nike:
1. Ancient Greek name (Νίκη) [niki], meaning - "victory; victorious; goddess of victory; epithet of Athena"
2. Mistakenly considered by some as a form of the name Veronika/Veronica - "girl who brings victory".
In Greek mythology Nike was a goddess of victory, also known as the Winged goddess. The Roman (Latin) equivalent is - Victoria. Depending upon the time of various myths, she was described as the daughter of Pallas (Titan) and Styx (Water) and the sister of Kratos (Strength), Bia (Force), and Zelus (Zeal). Nike and her siblings were close companions of Zeus, the dominant deity of the Greek pantheon. According to classical (later) myth, Styx brought them to Zeus when the God was assembling allies for the Titan War against the older deities. Nike assumed the role of the divine charioteer, a role in which she often is portrayed in Classical Greek art. Nike flew around battlefields rewarding the victors with glory and fame.
