In 1063, Ferdinand I of Castile divided his realm among his sons, and the Kingdom of Galicia was granted to Garcia II of Galicia. In 1072, it was forcibly annexed by Garcia's brother Alfonso VI of León; from that time Galicia was united with the Kingdom of León under the same monarchs. In the 13th century Alfonso X of Castile standardized the Castilian language and made it the language of court and government. Nevertheless, in his Kingdom of Galicia the Galician language was the only language spoken, and the most used in government and legal uses, as well as in literature.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was it that in 1063 gave rule over Galicia to his son?
Ah, so.. Ferdinand I

A striking technical innovation of the Komnenian period was the production of very precious, miniature mosaic icons. In these icons the small tesserae (with sides of 1 mm or less) were set on wax or resin on a wooden panel. These products of extraordinary craftmanship were intended for private devotion. The Louvre Transfiguration is a very fine example from the late 12th century. The miniature mosaic of Christ in the Museo Nazionale at Florence illustrates the more gentle, humanistic conception of Christ which appeared in the 12th century.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The more humanistic conception of Christ appeared when?
Ah, so..
in the 12th century
