actually, that doesn't look like an anatomically correct horse to me
in fact, i wouldn't be surprised if the rendering is inteded to . . . render
the (now extinct) species Hippidon, which, while a cousin to the
Equus family, was not directly linked to the modern horse (either Old or
New World species)
or, seeing as Hippidon went extinct about 4 million years ago, maybe the
image is meant to be that of a Equus hemionus, the desert-adapted onagers of
Asia & the Mideast, including the kiang
also, whatever the thing is, it is clearly alive. AS INDICATED by the splurting blood
which emanates from the blows. clearly, if the beast were dead, the blood would
have coagulated and thus any spurting would be out of the question.
at best, we can conclude from the image that someone (of identity unknown,
but probably someone of Caucassian origin, with a gene for baldness in the family)
is striking some sort of animal related to the horse, with what appears to be
a baseball bat, while the horse-like animal is lying on the floor, perhaps
quite close to giving up the ghost, but not quite there yet.
