Dionysus did not often travel alone. Wherever he went, he was usually accompanied by many servants and demi gods. Among these were the Maenads, Satyrs and Sileni; as well as the goat-footed god Pan and Priapus, the son of Dionysus and Aphrodite.
Maenads were women who became inspired and frenzied and took part in Dionysus's orgiastic rites. As with the mosiac to the left, often they are depicted holding the thrysus, a staff crowned with a pine-cone and adorned with leaves of ivy and vine. They would be so overcome by a divine madness and ecstasty that they indulged in large amounts of violence, sex, intoxication and frenzied dance. If they came across a wild animal, they would tear and eat its flesh, believing that in this way they made contact with the god, whom Zeus had once transformed into a goat.
The Satyrs and Sileni were spirits of the woods: these montrous creatures had the legs and tails of horses, exaggeratedly large genitalia, snub noses, curly hair, and long beards. The difference between the Sileni and the Satyrs seems to have been in the greater age of the former. Their sole occupation was to run through the forests, dancing and chasing the Nymphs and other pretty maidens. They also had a love of wine and are often depicted with winecups or appear on winecups as decorative figures.
Pan's origins start in Arcadia and he was one of the more important Arcadian pastoral gods. His cult spread throughout Greece as part of the orgiastic festivals held in honor of Dionysus, of whose companions he was one. The Greeks portrayed him with goat's feet, hirsute body, pointed beard, pointed ears, a crafty smile and the horns of an animal. Pan was known to be a vigorous god of the mountains and woods, a god whose life was devoted to hunting, singing, dancing and amorous adventures with the Nymphs (as well as members of the animal kingdom). Pan was one of Zeus' most faithful helpers during the Battle of the Giants. During the battle he let out wild cries which caused the enemies of the gods to take to their heels, thus originating the concept of panic. Later, Pan would become known for his music which could stir feelings of inspiration, sexuality, and panic.
Priapus was the son of Dionysus and the goddess Aphrodite. While he was still in the womb, Hera set upon him a curse that made him impotent, ugly, and foul-minded for the hero Paris having judged Aphrodite more beautiful than her. Eventually Priapus joined Dionysus, Pan, and the satyrs as a spirit of fertility due to the exaggerated size of his genetalia. Today, the medical term Priapism derives from Priapus.
