A modern of depiction of Satan in the likeness of a goat with horns and goatee.
Images of devils proliferated in the Middle Ages. The devil was often depicted as a terrifying, horned beast. In this mosaic by Coppo di Marcovaldo (1225-1276) in the Baptistery of Florence, Satan is devouring the damned while monsters in the shape of a snake, frog or lizard come out from his body.
In Christian art, the devil is typically portrayed as having horns of a goat and a ram, a pig's nose and teeth, and a goat's fur and ears. This image is a 16th-century painting by Jacob de Backer in the National Museum in Warsaw.
Historically, the devil had many names and roles.
He is the serpent who tempts Eve to eat the forbidden fruit, the fallen angel who rebelled against God, the Dragon, Beelzebub, the Father of Lies, Lucifer, Satan, the Prince of Darkness.
A giant beast, Lucifer, the King of Hell, stood frozen to the waist in a lake of ice in Dante's Divine Commedy.

A popular icon in the past, the devil appears to be alive and kicking also in Pope Francis' modernizing church. The pontiff has alluded to him ever since his first homily as Pope, describing the devil as a real presence even in the 21st century.
Unafraid of criticism for bringing back what many see as the superstitions of the middle ages, the Vatican last month faced the demonic threat by hosting its largest convention on exorcism. Called "Exorcism and Prayers of Liberation," the meeting included a six-day course to train about 200 Roman Catholic priests from more than 30 countries in the ancient rite of exorcism.
In this 1519 painting, an exorcism is being performed on a woman who has previously killed her child and her parents.
