Does anyone know if there is an available (published or unpublished) English translation of Johann Lambert's Theorie der Parallellinien? I was able to find it online in German by way of the bibliography of Jeremy Gray's Worlds out of Nothing at this link, but I have been unable to find it in English. Any help would be appreciated.
The place to go for everything related to Lambert is this one. Asking Maarten Bullynck, the author of this web site, might be a good idea.
