Zeus vs Hera

Yes, Zeus and Hera were siblings, both children of the Titans Cronus and Rhea. They are two of the six first-generation Olympian gods. Marriage between full siblings was taboo among mortals in ancient Greece, but the myths let gods break human rules, so their union became part of the divine order.

By trickery, according to myth. Hera resisted at first, so Zeus disguised himself as a wounded bird, often a cuckoo, and won her sympathy and trust before she agreed to marry him. Their wedding later served as the model for marriage and was celebrated in festivals such as the Theogamia.

Most accounts name Ares, Hephaestus, and Hebe as the children of Zeus and Hera, and some add Eileithyia, goddess of childbirth. Ares became the god of war, and Hephaestus the smith-god. Ancient sources differ, and some myths say Hera bore Hephaestus alone, so the lists vary.

Zeus. He ruled as king of the gods, and Hera could not truly punish him, so she aimed her anger at his lovers and their children instead. Hera was still queen of the gods and a powerful goddess of marriage, and her revenge showed she could make life very hard for those he favored.
