In regards to historical context, Liber Luratus Honorii (original text) is what holds value however there is no original copy in existence, the various examples the manuscript is based on are from later hand written copies (translated copies of the original), a variety of portions there-of that were preserved in a variety of European manuscripts (so take their value at what you will), J. Peterson's version (2016) is questionable at best as 1. He has no degree's in related fields to the occult (he has a degree in chemical engineering) He is a member of the folklore society and American the American academy of religion (which anyone can be a member of either) and membership to either cannot in good faith, hold any real credibility to the context of the occult. Though to his credit, he has written several (I belief at least 12) books on religious and magical subjects. The cautionary concern is A) the editing from the original text (which occurs with all material on the occult as there are several aspects of the occult that cannot be legally published (child sacrifice how-to, Animal sacrifice how-to, etc) B) the fact that his version is based on a variety of other copies which were hand written portions (not one completed text exists) that were from several different language translations, the issue with translating portions is the "lost in translation" that always occurs. The bible is a perfect example of this, translated from hebrew to greek then from greek to every other language. Hebrew has no J in its alphabet, so Jesus is not the correct translation (Yeshua is). Original text is what holds true value (both historically and otherwise) copies of copies however are questionable at best.
