HELIOS (SOL). The Sun god is known by the rays which encircle his head (Fig. 9). On coins of the Imperial period he is often seen driving the chariot of the Sun. POSEIDON (NEPTUNE). The head of this god much resembles that of Zeus, but may usually be distinguished from it by the absence of the laurel wreath, and by the heavy way in which the dank locks of his hair fall about his neck (Figs. 10 and 11). Poseidon is sometimes seated on rocks holding a trident and a dolphin or an aplustre (Fig. 12). [Illustration: Fig. 9. Helios (Sol).] [Illustration: Fig. 10. Poseidon (Neptune).] [Illustration: Fig. 11. Poseidon (Neptune).] Sometimes he stands resting on his trident, and sometimes he wields it on high as if about to strike. Occasionally he is seen on horseback armed with his trident. He is called _Poseidon Hippios_ (Fig. 13). [Illustration: Fig. 12. Poseidon (Neptune).] [Illustration: Fig. 13. Poseidon (Neptune).] [Illustration: Fig. 14. Dionysos.] DIONYSOS (BACCHUS). The head of Dionysos is either youthful or bearded, and is encircled by a wreath of ivy (Figs. 14, 15, and 16). His full-length figure is usually naked, or with merely a fawn skin hanging from his shoulder. He holds a wine cup (kantharos), or a bunch of grapes or the Bacchic staff (thyrsus), surmounted by a pine cone. Sometimes he has bull’s horns growing from his forehead, and on coins of Neapolis he appears as a bull with a human head (_Dionysos Hebon_). [Illustration: Fig. 15. Dionysos (Bacchus).] [Illustration: Fig. 16. Dionysos (Bacchus).] [Illustration: Fig. 17. Hermes (Mercury).] [Illustration: Fig. 18. Hermes (Mercury).] HERMES (MERCURY). The head of Hermes is youthful, and wears a hat called a _petasus_ (Figs. 17 and 18), close fitting, sometimes with a broad flapping brim and adorned with two wings. When his entire figure is represented, he is usually clad in a short cloak (_chlamys_), and has winged sandals (_pedilia_) on his feet. As the messenger of the gods and the conductor of the souls of the dead, he carries the winged staff (_caduceus_), and sometimes, as god of trade, a purse. HEPHÆSTUS (VULCAN). This god is sometimes young and sometimes bearded. He wears a conical hat (_pilos_), (Fig. 19). On coins of Lipara he is generally seated naked on a four-legged stool, holding a hammer in one hand and a cup (_kantharos_) in the other (Fig. 20). The tongs and the anvil are also emblems of the worship of Hephæstus. [Illustration: Fig. 19. Hephæstus (Vulcan).] [Illustration: Fig. 20. Hephæstus (Vulcan).] [Illustration: Fig. 21.
