"2 German illustrations of the crumhorn consort. Left: From Sebastian Virdung, Musica getutscht, 1511, showing 4 crumhorn sizes, though the text describes only 3. Could the smallest be Corteccia's stortina and Praetorius' exilent? Next to them is a ""Platerspil"", a bladder pipe. Bottom left: Illustrations identical to Virdung but reversed in Martin Agricola, Musica instrumentalis Deudsch, 1529, also with a ""Platerspiel"", a bladder pipe."
