We don’t know a lot about this porcelain rhinoceros. In fact, I don’t know for certain that it’s made of porcelain. It’s some sort of ceramic and it’s white, which generally implies kaolin clay and porcelain. It’s glazed mostly green and it has an interesting pattern in the glaze, possibly from the firing technique. It gives the figurine a more natural appearance, because rhinoceroses are not a uniform color (or course, they aren’t green, either, but that’s another matter). There are currently five extant species of rhinoceros, two native to Africa (the white and the black rhino) and three to Asia, the Indian, the Javan, and the Sumatran rhinos. I’m going to go with this being an Indian rhinoceros (Rhinoceros unicornis) and guess that the figurine came from central Asia somewhere, but of course it could easily have been bought in the United States.
