A damsel named Avenable went to the court of Julius Caesar, disguised as a page, and calling herself Grisandoles, after Frolle (Frollo) had driven her father and mother away from their country. The Emperor of Rome made her a seneschal of all his land.
She introduced Merlin to the court and eventually married Julius Caesar.
