A Dictionary of the Book of Mormon/Coriantum (II)
CORIANTUM. A Jaredite prince, the son of Omer; he was born while his father was held in captivity by his brother Jared. When Coriantum grew to manhood he became exceedingly angry at the course pursued by Jared, and with another brother, Esrom, he raised an army and made an unexpected night attack upon the forces of Jared, in which the latter were almost entirely destroyed. They then restored their father to the throne. (See Akish.)
