Josef Matyáš Lassler (1699–1777) jako malíř oltářních obrazů : několik slov o neznámé stránce tvorby opavského umělce

This article describes an as yet unkown side of the work of Opava artist Joseph Matthias Lassler (1699–1777). Known as a creator of fresco decorations, he has recently been discovered to have also been a super painter of altar paintings. From the results of recent field research it was possible to attribute thirty-six such paintings to Lassler, which he created for clients from almost all over Upper Silesia. Thanks to this discovery, it is possible to regard Lassler as one of the most productive painters of altar paintings working in that region in the second and third quarters of the 18th century.
