Meaning and history
This name is derived from Latin leo meaning "lion", a cognate of Leon. It was popular among early Christians and has been the name of 14 popes, including Saint Leo the Great who asserted the dominance of the Roman bishops (the popes) over all others in the 5th century. It was also borne by six Byzantine emperors and five Armenian kings. Another famous bearer was the Russian novelist Leo Tolstoy (1828-1910), name spelled Лев in Russian, whose works include War and Peace and Anna Karenina. Leo is also a constellation and the fifth sign of the zodiac. In some cases this name can be a short form of longer names that start with Leo, such as Leonard.
