San Esteban de Gormaz
By 1 September 1166 Pedro was a count ("comes" in Latin), the highest dignity to which a Castilian nobleman of his time could be appointed by the king. He regularly titled himself "Dei gratia", "by the grace of God", a rare usage for a nobleman in twelfth-century Spain, perhaps borrowed from his Occitan or Catalan cousins. There is also an example of his use of the phrase "munere divino" ("by divine mercy"). In 1168 he was sent to govern the "tenencias" of Osma and San Esteban de Gormaz in eastern Castile. On 4 October that year he made a donation to the parish church of Molina.
