I was hoping to find a copy of René Descartes treatment of rainbows as part of Project Gutenberg (hopefully in English) but no dice. It does appear that the Université de Québec has the work Les Météores as part of their online collection. It’s far too late for me to work on reading it (my French is pretty rusty, especially without my French dictionary) but I’ll have to have a look at it some other time.
Les classiques des sciences sociales: René Descartes, Les Météores (1637).
Thank you for sharing, nice to see they have a PDF. I don’t read French either, so like you I wont be able to read it without a dictionary but at least its on my hard drive now.
Thanks again for the link.
