In Greek mythology, Zelus or Zelos /ˈziːləs/ (Greek: Ζῆλος, Zēlos, literally "zeal") was the son of Pallas and Styx.[1] Zelus and siblings Nike (Victory), Kratos (Strength) and Bia (Force) were winged[citation needed] enforcers who stood in attendance at Zeus' throne and formed part of his retinue.[2]
Zelus personifies dedication, emulation, eager rivalry, envy, jealousy, and zeal.[citation needed] The English word "zeal" is derived from his name.[citation needed]
Zelos may have also been identified with Agon, and was closely connected with Eris.[citation need
