Mahound and Mahoun are variant forms of the name Muhammad, often found in Medieval and later European literature. The name has been used in the past by Christian writers to vilify Muhammad. It was especially connected to the depiction of Muhammad as a god worshipped by pagans, or a demon who inspired a false religion.
The perception that Muslims worshipped Muhammad was common in the Middle Ages. According to Bernard Lewis, the "development of the concept of Mahound started with considering Muhammad as a kind of demon or false god worshipped with Apollyon and Termagant in an unholy trinity in The Song of Roland. Finally, after the Reformation, Muhammad was seen as a cunning and self-seeking imposter."
The name appears in various medieval mystery plays, in which Mahound is sometimes portrayed as a generic "pagan" god worshipped by villains such as Herod and the Pharaoh of the Exodus. One play depicts both Herod the Great and his son Herod Antipas as worshipping Mahound, while in another play Pharaoh encourages the Egyptians to pursue the Israelites into the Red Sea with the words: Heave up your hearts ay to Mahound.
"The Deil cam fiddlin thro' the town,
And danc'd awa wi' th'Exciseman;
And ilka wife cries auld Mahoun,
I wish you luck o' the prize, man."
G. K. Chesterton uses "Mahound" rather than "Mohammed" in his poem Lepanto. More recently, Salman Rushdie, in his novel The Satanic Verses, chose the name Mahound to refer to Muhammad as he appears in one character's dreams. However, he is not identified as Satan in that work.
