In 1554 Apian was commissioned by Duke Albrecht V of Bavaria to chart Bavaria. After seven years of land surveying Apian created an about 6 x 6 meter large map of 'Old Bavaria' on a scale of 1:45.000, completed in 1563. After this large map Jost Amman made 24 woodcuts on a scale of 1:144.000, which were published by Apian in his own printing house. In 1579 a new edition of the 'Baierische Landtafeln' was engraved and published by Peter Weiner (d. 1583) in Munich. The maps were made on the same scale as copper engravings and with a few place names added.
