In Hans Baumann's book "Lion Gate and Labyrinth" (trans. Stella Humphries, line drawings by Hans Peter Renner, Oxford University Press 1967), which relates the stories of Schliemann's discovery of Troy and Evans' discovery of the Palace of Knossos, there are a number of line illustrations of Cretan seal stones.
These have no cross references to the originals so I wonder if anyone recognises where these three are from...
I'm particularly interested in the third one's provenance.
