Jakob Sandtner (born in Straubing, Germany) was a master turner and lived in the 16th century.
A few years earlier, Albrecht had obliged the mathematician Philipp Apian to create a map of Bavaria.
They were intended as jewelry for the Kunstkammer in Munich, which Albrecht had established around 1563/67, and after their completion were installed there as part of the Bavaria illustrata, which also included the Bavarian land tablets of Apian.
Albrecht also wanted to use the models to express his claim to power over the residence cities of the Bavarian duchies, which had been reunited since the end of the War of the Succession of Landshut in 1506.
Not much is known about how Sandtner works, but due to the high level of detail in the models, the production must have been accompanied by extensive measurements.
A city model of Jerusalem also appears in the inventory of the Kunstkammer by Johann Baptist Fickler in 1598, which is also in the National Museum today.
