Lots of fun to create poetic etymological narratives imbued with latent allusions
From the Germanic name Hrodebert meaning “bright fame”, derived from the Germanic elements hrod “fame” and beraht “bright”. The Normansintroduced this name to Britain, where it replaced the Old English cognateHreodbeorht. It has been consistently among the most common English names from the 13th to 20th century. In the United States it was the most popular name for boys between 1924 and 1939 (and again in 1953).
This name has been borne by two early kings of France, two Dukes of Normandy, and three kings of Scotland, including Robert the Bruce who restored the independence of Scotland from England in the 14th century. The author Robert Browning (1812-1889) and poets Robert Burns (1759-1796) and Robert Frost (1874-1963) are famous literary bearers of this name. Other bearers include Robert E. Lee (1807-1870), the commander of the Confederate army during the American Civil War, and American actors Robert Redford (1936-), Robert De Niro (1943-) and Robert Downey Jr. (1965-)
c. 1300 as the name of the bright reddish-orange planet in the heavens; late 14c. as the name of the Roman god of war, from Latin Mars (stem *Mawort-), the Roman god of war (identified with Greek Ares), a name of unknown origin, apparently from earlier Mavors, related to Oscan Mamers.
According to Watkins the Latin word is from *Mawort- “name of an Italic deity who became the god of war at Rome ….”
He also had agricultural attributes, and might ultimately have been a Spring-Dionysus. The planet was so named by the Romans, no doubt for its blood-like color. The Greeks also called the planet Pyroeis “the fiery.” Also in medieval alchemy, “iron” (late 14c.). The Mars candy bar was first manufactured in 1932 by Forrest Mars Sr. of the candy-making family.
