Histories

Then they fasten half of a wheel to two posts, the hollow upward, and the other half to another pair of posts, until many posts thus prepared are planted in the ground, and, after driving thick stakes lengthways through the horses' bodies to their necks, they place the horses up on the wheels

so that the wheel in front supports the horse's forequarters and the wheel behind takes the weight of the belly by the hindquarters, and the forelegs and hindlegs hang free; and putting bridles and bits in the horses' mouths, they stretch the bridles to the front and fasten them with pegs.

Then they take each one of the fifty strangled young men and mount him on the horse; their way of doing it is to drive an upright stake through each body passing up alongside the spine to the neck leaving enough of the stake projecting below to be fixed in a hole made in the other stake, which passes through the horse. So having set horsemen of this fashion around the tomb, they ride away.
