The name of Saint Sophia’s Cathedral in Kiev comes from the sixth-century Hagia Sophia cathedral in Constantinople (meaning Holy Wisdom, and dedicated to the Holy Wisdom rather than a specific saint named Sophia).

According to a less popular theory, its model was the thirteen-domed oaken Saint Sophia Cathedral in Novgorod (constructed around 989), which Yaroslav I the Wise had determined to imitate in stone as a sign of gratitude to the citizens of Novgorod, who had helped him secure the Kievan throne in 1019.

In Baghdad, a revolt by Basasiri against the Seljuqs, who had taken the city in 1055, receives support from Thimal.

By 1057, however, Thimal is having difficulties with the Kilab, who are displeased that they are not treated as well as his Numayrid allies.

The Mirdasids decide that the situation is beyond dealing with and offer to give the Fatimid caliph Aleppo in exchange for several coastal towns, including …
