A Battle from the Trojan War, by the First Master of the Bible historiale of Jean de Berry (French, active c.1390-1400). In Greek mythology, the Trojan War was waged against the city of Troy by the Achaeans (Greeks) after Paris of Troy took Helen from her husband Menelaus king of Sparta. The war is one of the most important events in Greek mythology and has been narrated through many works of Greek literature, most notably through Homer's Iliad and the Odyssey.
