Originally plural (Sileni), but later mentioned as one Silenus, the teacher and faithful companion of the wine-god Dionysus. A notorious consumer of wine, he is usually totally drunk and is supported by satyrs or carried by a donkey. When the Phrygian king Midas took the drunk Silenus in his house, Dionysus handsomely reward Midas for his hospitality. He has much wisdom and if captured by mortals he can reveal important secrets.
Silenus is usually portrayed as a plump jovial old man with a long beard and stump nose, bald and with a horse's tail.
