Synopsis

Numerous ivory diptch sundials are known in the standard literature and can be found in various museum collections. Most of them are made by members of the well-known families Karner, Miller, Tucher, Troschel and Reinman, and a few others with a limited number of surviving pieces. This is not, of course, to underestimate their importance, such as that of Erhard Etzlaub, Georg Hartmann or Christian Heiden. But if we look at the archival material, there have been many more masters with almost no evidence by surviving pieces. This talk will shed light on some of the rare masters and some rare mastermarks.
