used the name Septentrio, which refers to the seven () stars of the Plow or Big Dipper constellation. The name "Septentrio" gave rise to the pre-modern compass point Septentrionalis. Zephyrus (Favonius) Zephyrus (Gk. []), sometimes shortened in English to Zephyr, is the Greek god of the west wind or continental tropical air mass (cT). The gentlest of the winds, Zephyrus is known as the fructifying wind, the messenger of spring. It was thought that Zephyrus lived in a cave in Thrace. Zephyrus was reported as having several wives in different stories. He was said to be the husband of Iris, goddess of the rainbow. He abducted the goddess Chloris, and gave her the domain of flowers. With Chloris, he fathered Karpos ('fruit'). He is said to have vied for Chloris's love with his brother Boreas, eventually winning her devotion. Additionally, with yet another sister and lover, the harpy Podarge (also known as Celaeno), Zephyrus was said to be the father of Balius and Xanthus, Achilles' horses. In the story of Eros and Psyche, Zephyrus served Eros (or Cupid) by transporting Psyche to his abode. Zephyrus was also claimed to have killed one of Apollo's many male lovers Hyacinth out of jealousy. Hyacinth was killed by a discus thrown by Apollo. Though according to some sources, his death was said to be an accident, others said that Zephyrus was the true culprit, having blown the discus off course. Zephyrus' Roman equivalent was Favonius (the "favouring") who held dominion over plants and flowers. The Roman poet Horace writes: Notus (Auster) Notus (, ) was the Greek god of the south wind or marine tropical air mass (mT). He was associated with the desiccating hot wind of the rise of Sirius after midsummer, was thought to bring the storms of late summer and early autumn, and was feared as a destroyer of crops. Notus' equivalent in Roman mythology was Auster, the embodiment of the sirocco wind, a southerly wind which brings cloudy weather, powerful winds and rain to southern Europe. (Auster named the compass point Australis and the country's name Australia.) The Auster winds are mentioned in Virgil's Aeneid Book II, lines 304–307: Another Roman poet, Tibullus 1.1, lines 47–48, speaks of the pleasure of lying in bed on rainy winter days: The name Australia (the "southern land") is derived from Auster. Eurus (Vulturnus) Eurus (, ) according to some was the southeast
