Ramses II, one of ancient Egypt's greatest pharaohs, is said to have fathered more than 100 children, including 52 sons. Archeologists have now discovered an enormous mausoleum with at least 67 chambers, the largest tomb ever explored in the Valley of the Kings, and they think this was the resting place for most of those royal sons.The sons never attained the power of their father, whose reign lasted 66 years.
