Adeliza (c.1103 - 1151) was 17 or 18 when she wed Henry in 1121, who was about 35 years older than she. She was even younger when negotiations started; Henry had already been looking for a second wife, but the process accelerated after the White Ship. Sometimes called "the fair maid of Brabant," she was known for her beauty. The historian Henry of Huntingdon (once mentioned here) raved that her beauty was completely natural, needing no adornment.
One of her attractive features (aside from her physical features) was her ancestry: as a descendant of Charlemagne, marriage to her would link their children to an age still looked upon as glorious and foundational to contemporary Europe. The two were wed in Windsor Castle on 24 January 1121. They were married for 15 years, during which time she seemed to have always been near him as he traveled his kingdom. She took little interest in administrative duties, however, unlike many queens.
She did, however, turn out to be a patron of the arts, sponsoring French poets. An Anglo-Norman poet, Philippe de Thaon, dedicated a Bestiary in Latin to:
...an outstandingly beautiful woman.
And she is courtly and wise, Of good customs and generous:
She is called 'Aaliz', Queen is she crowned,
She is the queen of England; May her soul never know trouble!
