Does anyone know if there is an available (published or unpublished) English translation of Johann Lambert's *Theorie der Parallellinien*?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](http://openlibrary.org/books/OL23347640M/Die_theorie_der_parallellinien_von_Euklid_bis_auf_Gauss), but I have been unable to find it in English. Any help would be appreciated.



English translation of Lambert's Theorie der Parallellinien?
The place to go for everything related to Lambert is 
[this one](http://www.kuttaka.org/~JHL/Werke.html). 
Asking Maarten Bullynck, the author of this web site, might be
a good idea.
