Seven Deadly Sins

"The classification of the "seven deadly sins" dates back to as early as the 6th century, when they were first grouped together by St. Gregory the Great, Pope from 590-604. The sins – pride, covetousness, lust, envy, gluttony (including drunkenness) anger, and sloth – were held to be transgressions that caused the death not of the body but of the soul. In the mid-13th century Guilielmus Peraldus composed a treatise on the seven deadly sins called the Summa seu Tractatus de Viciis, and it soon became the most influential source on the subject, fascinating and inspiring Medieval and Renaissance writers including Thomas Malory, Geoffrey Chaucer, John Gower, Langland, Dante, Spenser, and Marlowe."
