Answer:
In Greek mythology, Zeus, the king of the gods, made a promise to Thetis, a sea nymph and mother of the hero Achilles. The promise Zeus made to Thetis was to help her son Achilles in the Trojan War, which was a conflict between the Greeks (Achaeans) and the Trojans. According to the myth, Thetis sought the aid of Zeus after Achilles' armor was taken by the Trojan prince Hector. Zeus promised to fulfill Thetis' request and aid Achilles in avenging Hector's actions. As a result, Zeus sent the god Hephaestus to forge a new set of armor for Achilles, which he used to achieve great feats in the Trojan War. This promise by Zeus to Thetis is often mentioned in ancient Greek literature and mythology as an example of divine intervention in human affairs.
