People believed that the outcome of syphilis was God's severe punishment for lascivious men. Juan Almenar (15th-16th century) named the disease passio turpis saturnina in remembrance of the filthy passion of Saturn, a Roman divinity, known as Kronos in Greek mythology, who killed his own sons by eating them.1 Almenar stated, “Venereal disease is a diathesis which is owed to the sexual trade . . . at the beginning it shows some ulcers . . . on the genital organs . . . subsequently it affects the humours, especially . . . the seminal fluids. ” Shortly after syphilis was introduced in Europe, physicians began to realize that the disease was sexually transmitted, leading Jacques de B éthencourt (16th century) to use the synonym Gallic disease and the adjective venereal from Venus, the love goddess in Roman mythology, and Bernardino Tomitano (1517-1576) to call it bad Venus. Hermann Boerhaave (1668-1738) called syphilis aphrodisiaca lue, from the Latin word lues, meaning disease, contagious, endemy, or plague, and Aphrodite, the love goddess in Greek mythology. This last appellative did not last long, but the term venereal lues, which was introduced by Giulio Cesare Vanini (1585-1619), was used in Italy until the first half of the 19th century.
