oh yeah, reminds me too, of the "space ships" on some orthodox church ceiling.

The church you're referring to is Dobarsko Church in Bulgaria, built in 1614

2. This Orthodox church features a distinctive fresco called The Transfiguration in its central dome, which depicts Christ "ready for takeoff in a spacecraft"

2. The church also contains other unique elements, including frescoes of the twelve apostles painted full-length
