I came across this statue on my way back from Amsterdam, spotted it across the canal and had to see what it was about. I looked for a plaque of explantation: a fable or perhaps a poem, but there was none.
It is a statue of a man carrying a jackass on his back, heading in no particular direction. Made in bronze in 1998 by the sculptor Gijs Assmann, perhaps it was a play on his name. Translated this is Ashman.
