While this looks like a polar bear rug, it was made by a taxidermist from ermine (a species of weasel). The “bear’s” teeth came from a mouse. The inspiration for this “rug” came from the Russian fairy tale that inspired the décor of the Prince’s Bedroom in the Fairy Castle. The Prince’s Bedroom is cast in bronze and the theme of the carvings on the bed and chairs is of Little Czar Saltar, an 1831 fairy tale by Russian author Alexander Pushkin. The walls are painted in Russian blue and the perforated ceiling is shaped like a canopy supported by pillars and decorated with animals and plants. The bed is carved from walnut and painted, and possessions of the Prince can be found throughout. Moore may have imagined the Prince as a descendant of a Russian czar.
