This book was the first done in 1920 French language poorly done of the version of " the treaty of paint" on the codex VATICANUS (URBINAS) 1270" from 1888, for it had missing diagrams and still not in the full amount of the original "treaty book of paint" from the rambling together of its not in order, as well of number listing missing in its original context, Which I had redone for easier usage to study from and to be able to compare the different between the 1888 German Italian version of it, this one. Which had to work out the translation from many other writings from earlier books in French too see the missing parts to give it the closest to the spirt of the original authors intent of the writing that I see lacked while working in it.
