Please note that even things written in 1620 can be under copyright. Not the original thing, but the translation, if it is recent. Generally, every time a book is modified, the clock starts ticking anew… for the modified version. If you use a sufficiently old translation, or translate a sufficiently old text yourself, then it’s okay (even if a newer translation exists, if you didn’t use it).

Yup – Ruby/habryka specifically found a translation that we’re allowed to post.
