Where was Christ Pantocrator usually placed in a Byzantine church’s decoration?

In the context of Byzantine church decoration, the figure of Christ Pantocrator (the All-Ruler) was typically placed at the very top of the central dome.12

This placement was a key element of the hierarchical iconographic scheme used in middle Byzantine churches, which functioned as a microcosm of the universe. In this arrangement, Christ presided from the highest point, while angels, archangels, and saints were depicted in the zones below him, and the congregation occupied the lowest realm.12
