Death of al-Ghazali
The great Persian theologian who had walked out of his Baghdad professorship at forty, suffered a crisis of faith, spent a decade wandering as a Sufi, and returned to write an Islamic synthesis of reason and mysticism, died at his hometown of Tus. His influence on Sunni thought is hard to overstate.
Su Song's astronomical clock at Kaifeng
In the Song capital, the polymath official Su Song completed and described a thirty-foot-tall water-driven clock tower with an armillary sphere, celestial globe, and bell-striking puppets, accurate to within seconds a day. The machine would be dismantled by the Jurchen invaders a few years later. Su Song's treatise on the mechanism, illustrated with detailed diagrams, survives as one of the great documents of medieval Chinese engineering.
Ananda Temple completed at Pagan
King Kyansittha's architectural masterwork rose complete above the dusty Burmese plain at Pagan - a perfectly symmetrical cruciform temple housing four colossal standing Buddhas facing the cardinal directions, each over thirty feet tall. Gilded inside and out, adorned with hundreds of glazed terracotta tiles illustrating the Jataka tales, it became the spiritual heart of Theravada Buddhism in Southeast Asia.
Henry V crowned Holy Roman Emperor
After kidnapping Pope Paschal II and extracting an agreement at swordpoint in St. Peter's, Henry received the imperial crown from a pope whose fingers still trembled. The coerced settlement collapsed within weeks and plunged Germany back into civil war. The spectacle of a pope held hostage in his own basilica horrified Christendom and hardened the reformist clergy's determination to free the church from imperial interference once and for all.
