第一次ウィーン包囲
Unlike Howard's better-known fantasy work, "The Shadow of the Vulture" is historical fiction, set in the 16th century. It uses the career of Ottoman sultan Suleiman the Magnificent (also known as Sultan Suleiman I), the aftermath of the Battle of Mohács (1526) and the later Siege of Vienna of 1529 as a backdrop for imaginary characters and events.
