Thomas, S. th. Supp. 45) would have well made it possible for them to marry at once, without a priest, possibly taking their children as witnesses. Even more significantly, unmarried couples were fairly common throughout medieval society, and while the social standing of the woman would have been somewhat lowered by being a "concubine" and not a married woman, the fact itself carried no social stigma and scarcely provoked any intervention by law and church.

In reality, the Kingdom of Castile's plains, to which Toledo belonged, were famous for their extensive wheat fields.
