SOLVED. Book of mythological stories and characters, non-fiction [s]

[Phil]

I believe I last read it about 2015, the book appeared to be rather old, possibly written in the 1970's? I recall it using the archaic spelling "Moslem" when referring to Islamic countries. I believe it had an illustration depicting a giant towering over a ship in the ocean, and IIRC there was a story about a 100-meter long sea serpent attacking a boat? The book also had Dorian Grey and Faust in it, I think.
I do have images I am certain are from the book. I will link to them below:

I've got my copy in front of me and it absolutely has the red cap, bunyip, and basilisk/cockatrice illustrations you linked. I'm still checking out the others.

edit: Black Annis is there too and the Barbegazi. If it's not the book you're looking for I'll be astonished.
But on the off chance it's not, all those illustrations are by Robert Ingpen so that may help track down where else they might have been used.

That's it for certain, thank you so much! I always loved reading it and it was driving me crazy not knowing what it was!
