A Corpus of Rembrandt Paintings Online

the-rembrandt-databaseFor those familiar with Ernst van de Wetering’s Rembrandt – The Painter at Work and the Rembrandt Research Project, you may also be aware of the six-part series of Rembrandt books entitled A Corpus of Rembrandt Paintings.

If you’re not interested in paying the going rate for an actual volume (Volume I is currently selling for around $1,200 on Amazon), then there is reason to rejoice:

The first five volumes of the Corpus are available as free digital downloads on a website launched in 2012 called The Rembrandt Database.

I only just found it yesterday, so it seems a worthy cause to help spread the word.
