At the Rijksmuseum three days ago, before the main crush of crowd arrived, I spotted a couple of cranes in a 1680 painting, “The Floating Feather,” by Melchior d’Hondecoeter. The unmistakable spectacular Black Crowned Crane in the centre, which I’ve never seen, is found only in Africa. The other crane below and to the right of the big one seems to be a Sarus Crane (again, not yet sighted by me), which I understand is found only in Asia or northeast Australia. Why were these included? Did the artist see them live or just paint from specimens brought back from overseas? Fascinating.
