ZELOS was the spirit (daimon) of eager rivalry, emulation, envy, jealousy and zeal. He and his siblings, Nike (Victory), Bia (Force) and Kratos (Strength), were the winged enforcers of Zeus who stood in attendance of his throne.
Zelos may have been identified with Agon, spirit of contest, worshipped at Olympia. He was also sometimes equated with Phthonos the spirit of romantic jealousy, and was closely connected with the good Eris, strife as the driving force of competition.
|PALLAS & STYX (Hesiod Theogony 383, Apollodorus 1.9, Hyginus Preface)
ZELUS (Zêlos), the personification of zeal or strife, is described as a son of Pallas and Styx, and a brother of Nice. (Hes. Theog. 384 ; Apollod, i. 2. § 4.)

Hesiod, Theogony 383 ff (trans. Evelyn-White) (Greek epic C8th or C7th B.C.) :
"And Styx the daughter of Okeanos was joined to Pallas and bare Zelos (Zelus, Emulation) and trim-ankled Nike (Victory) in the house. Also she brought forth Kratos (Cratus, Strength) and Bia (Force), wonderful children. These have no house apart from Zeus, nor any dwelling nor path except that wherein God leads them, but they dwell always with Zeus the loud-thunderer. For so did Styx the deathless daughter of Okeanos plan on that day when the Olympian Lightener called all the deathless gods to great Olympos, and said that whosoever of the gods would fight with him against the Titanes, he would not cast him out from his rights, but each should have the office which he had before amongst the deathless gods. And he declared that he who was without office and rights as is just. So deathless Styx came first to Olympos with her children through the wit of her dear father. And Zeus honoured her, and gave her very great gifts, for her he appointed to be the great oath of the gods, and her children to live with him always. And as he promised, so he performed fully unto them all."
Hesiod, Works and Days 175 ff :
"Among the men of the fifth age . . . There will be no favour for the man who keeps his oath or for the just (dikaios) or for the good (agathos); but rather men will praise the evil-doer (kakos) and his violent dealing (hybris). Strength will be right (dike) and reverence (aidos) will cease to be; and the wicked will hurt the worthy man, speaking false words against him, and will swear an oath upon them. Envy (zelos), foul-mouthed, delighting in evil, with scowling face, will go along with wretched men one and all. And then Aidos (Shame) and Nemesis (Indignation), with their sweet forms wrapped in white robes, will go from the wide-pathed earth and forsake mankind to join the company of the deathless gods: and bitter sorrows (lugra algea) will be left for mortal men, and there will be no help against evil."
Pseudo-Apollodorus, Bibliotheca 1. 9 (trans. Aldrich) (Greek mythographer C2nd A.D.) :
"Nike, Kratos (Cratus), Zelos (Zelus), and Bia were born to Pallas and Styx. Zeus instituted and oath to be sworn by the waters of Styx that flowed from a rock in Haides' realm, an honor granted in return for the help she and her children gave him against the Titanes."
Pseudo-Hyginus, Preface (trans. Grant) (Roman mythographer C2nd A.D.) :
"From Pallas the giant and Styx [were born] : Scylla, Vis [Bia, Force], Invidia [Zelos, Jelousy], Potestas [Kratos, Power], Victoria [Nike, Victory]."
Oppian, Cynegetica 3. 236 ff (trans. Mair) (Greek poet C3rd A.D.) :
"O father Zeus, how fierce a heart hath Zelos (Rivalry)! Him hast thou made, O lord, mightier than nature to behold and has given him the bitter force of fire, and in his right hand hast vouchsafed to him to wear a sword of adamant. He preserves not, when he comes, dear children to their loving parents, he knows nor comrade nor kin nor cousin, when he intervenes grievous and unspeakable. He also in former times arrayed against their own children heroes themselves and hobble heroines."
