genealogy by Juan de Mena, the poet laureate and historiographer of John
II.

The origin of the name Cervantes is curious. Nuno Alfonso was almost as
distinguished in the struggle against the Moors in the reign of Alfonso
VII as the Cid had been half a century before in that of Alfonso VI, and
was rewarded by divers grants of land in the neighbourhood of Toledo. On
one of his acquisitions, about two leagues from the city, he built
himself a castle which he called Cervatos, because "he was lord of the
solar of Cervatos in the Montana," as the mountain region extending from
the Basque Provinces to Leon was always called. At his death in battle in
1143, the castle passed by his will to his son Alfonso Munio, who, as
territorial or local surnames were then coming into vogue in place of the
simple patronymic, took the additional name of Cervatos. His eldest son
Pedro succeeded him in the possession of the castle, and followed his
example in adopting the name, an assumption at which the younger son,
Gonzalo, seems to have taken umbrage.

Everyone who has paid even a flying visit to Toledo will remember the
ruined castle that crowns the hill above the spot where the bridge of
Alcantara spans the gorge of the Tagus, and with its broken outline and
crumbling walls makes such an admirable pendant to the square solid
Alcazar towering over the city roofs on the opposite side. It was built,
or as some say restored, by Alfonso VI shortly after his occupation of
Toledo in 1085, and called by him San Servando after a Spanish martyr, a
name subsequently modified into San Servan (in which form it appears in
the "Poem of the Cid"), San Servantes, and San Cervantes: with regard to
which last the "Handbook for Spain" warns its readers against the
supposition that it has anything to do with the author of "Don Quixote."
