Tag of a book illustration

I made a tag for a drawing thinking it would qualify as fine_art or similar because the creator is an artist, but it turned out to be an illustration from a book I haven't read.

the_spiritual_descent_of_lucifer_into_satan

The problem is:

• Someone told me that it doesn't have a proper name but rather a description or quote (Wikimedia University of Buffalo Libraries)
• 1 of other images from the book; it doesn't seem practical to tag all the other illustrations.

So, how to proceed? Create a tag called paradise_lost_(book) and delete the other tag?

Edit:

• If you accidentally create a non-relevant wiki page, you may delete it by clicking "Edit" and then clicking "Delete".

I'll deleted and create the tag for the book.

BUR #51514 has been approved by @evazion.

rename paradise_lost -> paradise_lost_(light)

On a related point the current PL tag should 100% be qualified as it's named after Milton's book here in the first place (Light being the Doujin Circle that made it)
