A Dictionary of the Book of Mormon/Coriantum
CORIANTUM. A good king of the Jaredites. He was the son of Emer, who, four years before his death, anointed Coriantum to reign in his stead. He was a righteous, just and vigorous ruler, and in his days the Jaredites were greatly prospered and many large cities were built. But he had no children until he was exceedingly old; his wife died when she was 102 years of age, after which he married a young maid, who bore him a large family. He lived until he was 142 years old, when he died, and was succeeded on the throne by his son Com.
