Then the Cid graciously went to meet his future sons-in-law. They were
escorted to the banks of the Tagus by Alfonso himself, who there
expressed surprise at the length of the Cid's beard, and seemed awed
by the pomp with which he was surrounded, for at the banquet all the
chief men ate out of dishes of gold and no one was asked to use
anything less precious than silver. Not only did the Cid assure his
future sons-in-law that his daughters should have rich dowries, but,
the banquet ended, escorted them back to Valencia, where he
entertained them royally.

The wedding festivities lasted fifteen days, but even after they were

more than one opportunity to regret having bestowed his daughters'
hands upon youths who possessed neither courage nor nobility of
character. While the young men were still lingering in Valencia, it
happened one afternoon--while the Cid lay sleeping in the hall--that a
huge lion, kept in the court-yard for his amusement, escaped from its
keepers. While those present immediately rushed forward to protect the
sleeper, the Cid's sons-in-law, terrified at the sight of the monster,
crept one beneath the hero's couch and the other over a wine-press,
thus soiling his garments so he was not fit to be seen. At the lion's
roar the Cid awoke. Seeing at a glance what had occurred, he sprang
forward, then, laying a powerful hand on the animal's mane, compelled
him to follow him out of the hall, and thrust him ignominiously back
into his cage.

Because the Infantes had so plainly revealed their cowardice, people
made fun of them, until they roused their resentment to such an extent
