In the New Testament Simon is the name of several characters, including the man who carried the cross for Jesus. Most importantly however it was borne by the leading apostle Simon, also known as Peter (a name given to him by Jesus).
Because of the apostle, this name has been common in the Christian world. In England it was popular during the Middle Ages, though it became more rare after the Protestant Reformation.
Roland was an 8th-century military commander, serving under Charlemagne, who was killed by the Basques at the Battle of Roncevaux. His name was recorded in Latin as Hruodlandus. His tale was greatly embellished in the 11th-century French epic La Chanson de Roland, in which he is a nephew of Charlemagne killed after being ambushed by the Saracens. The Normans introduced the name to England.
Jonah's story was popular in the Middle Ages, and the Hellenized form Jonas was occasionally used in England. The form Jonah did not become common until after the Protestant Reformation.
In modern times, this name is borne by American fashion designer Calvin Klein (1942-), as well as one of the main characters from Bill Watterson's comic strip Calvin and Hobbes (published from 1985 to 1995).
Arthur is the name of the central character in Arthurian legend, a 6th-century king of the Britons who resisted Saxon invaders. He may or may not have been based on a real person. He first appears in Welsh poems and chronicles (perhaps briefly in the 7th-century poem Y Gododdin and more definitively and extensively in the 9th-century History of the Britons [1]). However, his character was not developed until the chronicles of the 12th-century Geoffrey of Monmouth [2]. His tales were later taken up and expanded by French and English writers.
The name came into general use in England in the Middle Ages due to the prevalence of Arthurian romances, and it enjoyed a surge of popularity in the 19th century. Famous bearers include German philosopher Arthur Schopenhauer (1788-1860), mystery author and Sherlock Holmes creator Arthur Conan Doyle (1859-1930), and science-fiction author Arthur C. Clarke (1917-2008).
