From 1979, I highly recommend this Michael Moorcock adaptation by Howard Chaykin, published by Heavy Metal.

THE SWORDS OF HEAVEN, THE FLOWERS OF HELL


An intelligent story, and beautifully rendered by Howard Chaykin in some of his best painted art. Easier to find these days (God bless the internet!) but even back in the pre-internet 1990's when I first discovered it with much more difficulty, well worth seeking out.

There is also a newer 2018 printing of this book by another publisher.
