The third-century Greek biographer Philostratus records a legend in his Life of Apollonius of Tyana of how the ghost of an Aethiopian satyr was deeply enamored with the women from the local village and had killed two of them. Then, the philosopher Apollonius of Tyana set a trap for it with wine, knowing that, after drinking it, the ghost-satyr would fall asleep forever. The wine diminished from the container before the onlookers' eyes, but the ghost-satyr himself remained invisible. Once all the wine had vanished, the ghost-satyr fell asleep and never bothered the villagers again. Amira El-Zein notes similarities between this story and later Arabic accounts of jinn. The treatise Saturnalia by the fifth-century AD Roman poet Macrobius connects both the word satyr and the name Saturn to the Greek word for penis. Macrobius explains that this is on account of satyrs' sexual lewdness. Macrobius also equates Dionysus and Apollo as the same deity and states that a festival in honor of Bacchus is held every year atop Mount Parnassus, at which many satyrs are often seen.
