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.
Phthonus
In Greek mythology, Phthonus (, "Phthónos") was the personification of jealousy and envy, especially in matters of love. He was said to be the counterpart of Nemesis. However, his power influenced not only himself and mortals, but also the gods as well (most famously Hera). It was he that directed Hera's attention to Zeus' many affairs, including one of his most famous, that with the Theban princess Semele. He also put the thought into Hera's mind to trick Semele into convincing Zeus into showing Semele his full glory, which killed her.
