The fall of the angel, brought low by the serpent, isn't one that immediately made me think of this station. But it did strike me that Jesus, on his third fall, fell like a man and like a man was going to perish by the same evil that the serpent represents. Even an angel can be brought down. So went Jesus, down for the last time, a seeming fall from grace, but in doing so demonstrating his connection with humanity.
This statue of the fallen angel is in a park in Madrid (Spain, June 1986)
