By the time of his death, in 1918, Walter Potter had stuffed more than ten thousand specimens for his museum, but his greatest taxidermy tableau remains his first, The Death and Burial of Cock Robin. The work, begun when Potter was only nineteen, reenacts the funeral from the nursery rhyme of the same name, which poses a series of questions such as “Who killed Cock Robin?” (“‘I,’ said the sparrow, ‘with my little bow and arrow’”) and “Who’ll dig his grave?” (“‘I,’ said the owl, ‘with my spade and shovel’”).

Nursery rhymes often contain morbid imagery: sightless mice being chased with a butcher knife (“Three Blind Mice”) and birds being methodically dismembered (“Alouette”), to name two that involve animal cruelty. Just as these verses take their unsettling power from their ability to soothe the macabre (horrific death!) into the ­quotidian (memorable ditty!), Potter’s work gains depth by casting dead animals as civilized humans: a frog shaves another frog, two guinea pigs play cricket, seventeen ginger tabby and white kittens partake in colorful pastries at a tea party. So it is in The Death and Burial of Cock Robin: Avian mourners perch on a leafless tree while others line up in pairs behind the coffin, heads lowered; several shed glass tears. The stuffed sparrow displays his bow and arrow, the owl grips a tiny shovel at the edge of the open grave, and the robin lies tucked inside an open, faded blue coffin. (The rhyme also mentions a bull, though instead of stuffing a real bull, which would have been impossible to fit into the glass case, Potter bought a hairless and skinless model a little larger than the owl, cut off the hair from a calfskin, and glued it to the model; the result looks eerily real.) The tableau also includes characters that never appear in the rhyme: nightingale, goldfinch, hawfinch, bramblefinch, bunting, cuckoo, butterfly. The pallbearer, a kite, is absent; kites were extremely rare, and ­Potter did not believe in killing animals for taxidermy’s sake.

If you find taxidermy revolting, consider human-embalming practices: we suction fluids from the internal organs with a hose, plug body cavities with cotton gauze, and fasten the mouth shut. Here is where questions of motives, or of artistic intent, enter. Both embalming and taxidermy attempt to preserve the memory of the dead, rejecting mortality in order to embrace it. An embalmer wants the viewer...
