 Guido, cardinal-deacon of SS. Cosmas and Damian, was promoted to the college of cardinals by Innocent II early in 1132 and was nominated papal chancellor by Eugenius III at the end of 1146. Between these dates he undertook three legatine journeys to Spain. The second of these occurred in 1136-7 and the third in 1143. The date of the first has never been satisfactorily established. It is known that during this first visit Guido held an ecclesiastical council, or attended a royal curia -- and for our purposes it does not matter which -- at the city of León. At this meeting the case of Bernardo of Compostela was discussed and Berengar, archdeacon of Toledo, was elected to the bishopric of Salamanca: these matters have been treated above, in chapter X. This assembly at León is referred to only in the Historia Compostellana, where it is not dated, though it seems to fall in 1134. Some historians have wished to place it in 1135 and to identify it with the curia held at León in the last week of May at which Alfonso VII was crowned emperor. But the Chronica Adefonsi Imperatoris, whose account of the imperial coronation and its associated gatherings is very full, says nothing of the cardinal's presence. This is an argument e silentio, but it seems to me to be a strong one. However, there is another, perhaps stronger. It has not been noticed by historians of Spanish affairs that cardinal Guido was sent on a mission to Milan in 1135 to win the city over from the antipope Anacletus to the Innocentian side in the papal schism that then divided western Christendom. It is just possible, but very unlikely, that he should have undertaken a legation to León-Castile as well in the same year. I maintain the contention advanced in chapter X that Guido's first legatine visit to Spain and the council of León belong to 1134, and that the council was probably held not later than August of that year.
