I couldn’t resist this little fellow. I don’t know how old he is or where he came from, with absolute certainty, though the seller suggested that he had come from the Black Forest. That seems quite likely given the quality of the work and the fact that it appears to be made from lime wood, which was much used in Germany. I’ve checked my various reference works and I see nothing else with a carved wood animal finial.
There is not a lot I can say about this object. It’s not perfect – much of the ear away from the camera has been lost. That’s a pity but it doesn’t affect the function and it barely affects the aesthetics. It’s my guess that the part that the nib goes in is bone rather than ivory. So far as I can, given that I can’t write with a dip pen, I’ve tried it and it seems perfectly practical.
