Astronomical clock, St. Nicholas Church, Stralsund

The clock features a self-portrait of its maker Nikolaus Lilienfeld, which is considered to be the oldest portrait of a clockmaker in the German-speaking world.

In August 1942, the clock dial was moved to the tower of St. Mary's Church, Grimmen, to protect it from damage during the War.

The clockwork's missing parts were not reintroduced for reasons of conservation, so the clock was deliberately not restored to working order.

In the four corners, the Four Wise Men are depicted: On the narrow left side wall of the clock, windows are painted; Nikolaus Lilienfeld, the clockmaker, looks out of one.

The panel paintings either side of the window depict, on the left, a man pushing a door open, with the Latin banner "post deum omnium vivencium vita sol et luna" (After God, the sun and the moon are the life of all living things), representing the morning, and on the right, a man pulling a door closed, with the Latin banner "matutinae imensa munera sed saepe male finiunt" (The morning promises rich rewards, but things often finish badly), representing the evening.
