A fine example of the Matthias Quad map of most of Switzerland engraved by Johann Bussemacher and published in Cologne. The map is drawn from the Abraham Ortelius of 1570, itself taken from the that of Aegidius Tscudi who was born in Glarus, Switzerland, in 1505. From 1524 he travelled extensively in the Alps and wrote a manuscript book with map of his travels. He intended to publish them but became involved in local politics instead. The map was printed separately in 1538 and no example survives. It is only known by a later re-print from the same block in 1560 which in itself survives in just one known example.
