Cid, Sol, and Elvira As portrayed in El Cid

So Rodrigo departed from the King, and took his spouse with him to the house of his mother, and gave her to his mother's keeping.

And forthwith he made a vow in her hands that he would never accompany with her, neither in the desert nor in the inhabited place, till he had won five battles in the field.

And he besought his mother that she would love her even as she loved him himself, and that she would do good to her and show her great honour, for which he should ever serve her with the better good will.

And his mother promised him so to do; and then he departed from them and went out against the frontier of the Moors.
