I discovered this morning that the entire Gottorfer Codex (danish: Gottorpsk Codex) is available on issuu. The Gottorfer Codex is a beautiful collection of gouache paintings on vellum depicting the flowers in the garden of Gottorf Castle (Schloss Gottorf) which is in Northern Germany near the Danish border.
The duplicates of the original images (which were all created between 1649 and 1659) are in the public domain and some of them are even available at very hi resolution (here) so you can download them to use as you wish.
These are a few of my favorites…I think at least I will put them in my rotation of screensavers and I am pondering other ways to play with them. Of course anyone can print and frame them, but I have been wanting to play with collage…any have any other ideas?
