Nike (mythology)
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 Titanomachy 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, symbolized by a wreath of laurel leaves (bay leaves).
Nike is seen with wings in most statues and paintings, with one of the most famous being the "Winged Victory of Samothrace". Most other winged deities in the Greek pantheon had shed their wings by Classical times. Nike is the goddess of strength, speed, and victory. Nike was a very close acquaintance of Athena, and is thought to have stood in Athena's outstretched hand in the statue of Athena located in the Parthenon. Nike is also one of the most commonly portrayed figures on Greek coins. After victory at the Battle of Marathon, Athenians erected the Nike of Callimachus.
Xenia (Greek)
The Greek god Zeus is sometimes called Zeus Xenios in his role as a protector of guests. He thus embodied the religious obligation to be hospitable to travelers. Theoxeny or theoxenia is a theme in Greek mythology in which human beings demonstrate their virtue or piety by extending hospitality to a humble stranger "(xenos)", who turns out to be a disguised deity "(theos)" with the capacity to bestow rewards. These stories caution mortals that any guest should be treated as if potentially a disguised divinity and help establish the idea of "xenia" as a fundamental Greek custom. The term "theoxenia" also covered entertaining among the gods themselves, a popular subject in classical art, which was revived at the Renaissance in works depicting a Feast of the Gods.
