Museum in the former home of the master of arithmetic Adam Ries in Annaberg-Buchholz, with a treasury of historic arithmetic books and a calculation school.
The exhibition shows counting tokens (Rechenpfennige) that were minted in Saxony or bear Saxon motifs, and explains how they were made and used historically. Created in cooperation with the Münzkabinett of the Staatliche Kunstsammlungen Dresden.
About the museum
Adam Ries (1492–1559), who popularized calculating with Hindu-Arabic numerals through his German-language arithmetic books, bought a property in Annaberg's Münzviertel (Mint Quarter) in 1525 and lived there as a master of arithmetic and mining official. The house, built around 1500, burned down almost completely in the town fires of 1604 and 1731; the present stone building dates from 1733, while the cellar rooms are still from around 1500. Later the building housed, among other things, a wine merchant with a wine tavern.
After stabilization work in the 1950s, the Adam Ries Museum opened on 30 March 1984, the 425th anniversary of the master's death, as part of the Erzgebirge Museum. A reopening followed for his 500th birthday in 1992, and in 1993 the Adam-Ries-Bund established the Annaberg calculation school. The association has run the museum since 1999; in 2008 the exhibition was completely redesigned.
The house is regarded as the only memorial to Adam Ries in the world located in a building he lived in himself, and is part of the UNESCO World Heritage Site Erzgebirge/Krušnohoří Mining Region. The exhibition introduces the world around 1500, explains old measures, weights and coins, and shows original arithmetic books and the manuscript of his "Coß" in a darkened treasury.
