I've noticed there are multiple versions of Bulfinch "the age of fable".
The one in project Gutenberg (standalone version, equal to the Amazon free version) contains a chapter on the "aryan family" and has language that looks like it's from the 1800s
Meanwhile, another version exists, as part of "Bulfinch mythology". This one has more accessible writing, has less text and misses the chapter on the "aryan family". This version is the same across different books on amazon (from different publishers), all of them less than a dollar (so this text is probably also in the public domain).
What's the story behind these two versions? Did Bulfinch do a rewrite, or did someone else do it?
I've read through the introduction of Charles Martin again, I think he didn't rewrite the text. He only provided the intro and footnotes. I did find something in this introduction saying that the combination of all stories into "mythology" was done after Bulfinch death. And also that there were many editorial changes: "After Bulfinch’s death, other editors stepped in, and as archaeological activities in the Near East advanced, they were able to provide editions of Bulfinch’s book with fables, as one of them put it, from “Babylon, Assyria and Phoenicia.” One suspects that Bulfinch would have approved." - my guess is that those edits were made a long time ago, which why they too are in the public domain and appear in all books on amazon (including the removal of the now racist bits)
