Satyrs
The satyrs were woodland spirits, often depicted in arts with head and upper body of man, horns and pointy ears, and goat legs. They were also depicted with large erect phallus.
They were often seen accompanying Dionysus, the god of wine and ecstasy. They were shown in drunken revelry and orgy, dancing with Dionysus' female followers, the maenads.
Pan, the god of shepherd was a satyr, so was probably Silenus or Seilenus. Silenus was one of the loyal followers of Dionysus, who brought up the wine god.
