Older or ancient, especially relating to the geological past. (Hope that answers your question :))
Explanation:
So first of all you need to look at the author and artist. Then you would need to find their attitudes towards slavery. Lastly you would need to find out how both attitudes are different from each other. Unfortunately I cannot give you a complete answer because I have not read the story and I don't know the author or artist. So just follow these steps and you should get farther. Let me know if you need any further help.
