Viola ca. 1660 Jacob Stainer Austrian Jacob Stainer is known as the "Father of the German violin" and his instruments were favorites of the Bach and Mozart families. They remained the most sought-after violins and violas in the world until the beginning of the 19th century. Stainers instruments are characterized by their very full arching, vertical f-holes with well-proportioned eyes and by their meticulous workmanship throughout.During the 17th century, violas were true tenor instruments with large bodies and often had tall ribs. As repertoire became more demanding, makers built smaller violas and cherished old instruments were cut down. This viola is one of the few surviving from the 17th century that has not been reduced in size.
