There is a lot of folklore about equestrian statues, especially the ones with riders on them. There is said to be a code in the number and placement of the horse's hooves: If one of the horse's hooves is in the air, the rider was wounded in battle; two legs in the air means that the rider was killed in battle; three legs in the air indicates that the rider got lost on the way to the battle; and four legs in the air means that the sculptor was very, very clever. Five legs in the air means that there's probably at least one other horse standing behind the horse you're looking at; and the rider lying on the ground with his horse lying on top of him with all four legs in the air means that the rider was either a very incompetent horseman or owned a very bad-tempered horse.
In the case of Michel Angelo we have an artist who with brush and chisel portrayed literally thousands of human forms; but with this peculiarity, that while scores and scores of his male figures are obviously suffused and inspired by a romantic sentiment, there is hardly one of his female figures that is so, the latter being mostly representative of woman in her part as mother, or sufferer, or prophetess or poetess, or in old age, or in any aspect of strength or tenderness, except that which associates itself especially with romantic love. Yet the cleanliness and dignity of Michel Angelo's male figures are incontestable, and bear striking witness to that nobility of the sentiment in him, which we have already seen illustrated in his sonnets.
