Erica asked me why I didn't include Jacob van Ruysdael in yesterday's post. Maybe I should have, but I left him out at first because I didn't remember him doing anything that related to Tuscany somehow. I looked him up in the Rijksmuseum's online collection. They have digitized their entire collection of paintings and made it searchable (the interface is in dutch, you have to click on zoeken) at http://token.rijksmuseum.nl.
A search for Ruysdael turned up two paintings by Jacob's uncle, Salomon van Ruysdael, one of which was a painting of the river near the village where I grew up.
For those of you who don't read dutch, I've translated the search form
