The first anthology of Spanish proverbs, Proverbios que dicen las viejas tras el fuego, was written by Íñigo López de Mendoza, 1st Marquis of Santillana in the 15th century.
Also in the 15th century was written the Seniloquium, an erudite and anonymous work containing a compendium of Spanish sayings and proverbs with commentaries.
[citation needed] Then, of course, in the 17th century there is the renowned book Don Quixote by novelist Miguel de Cervantes.
His thinking habitually relies on the authority he vests in the wealth of popular cultural wisdom expressed in proverbs, which he continually quotes.
In contrast, his master Don Quixote draws his references from chivalric romance books and is surprised that Sancho can find suitable proverbs for every circumstance.
