Fishburn and Hughes: "In Greek mythology the herald or messenger of the gods, the protector of herdsmen and the god of science, commerce, invention, the arts and, above all, travellers. In this last role Hermes was also the guide of the souls of the dead to their final abode (psychopompos). In art he is usually represented as a vigorous youth with winged helmet and sandals. A guide in both life and death, Hermes is referred to as two-faced." (89).
