I despise the widely controversial author even if he helped to inspire Buddha (10/10) should be your next step on your journey of self-discovery through manga. On the manga´s "educational" value:
My review states all and the manga is way better at representing the text in a visual way then as an adaptation. The poem is a bit hard to read now but lives of its vivid prose and that aspect is straight out lost here. Some changes and streamlining also took place and the manga loses steam as it marches on but you will certainly learn a few things along the way so read it along with an audiobook of the poem.

and i posted links to Gustave Doré 11/10 paintings in the thread too.
You may know Nagai Go as the author of crazy comedies or insanely violent dramas. Just like Tezuka, Nagai was moulding "manga" as an art medium to what we read now. And exactly like Tezuka who wrote many great works for adults even Nagai created some pieces which could be called "high art".
By now you've probably guessed that Dante Shinkyoku is one of these pieces. Before reading you should know that this isn't 100% adaptation of the original (which is great, by the way).Nagai gives his own explanations for some iconic scenes, he skips some minor parts, combines two characters into one and so on. But despite all of this, Dante Shinkyoku is noteworthy manga with good plot and nice drawings. How Nagai recreates famous paintings is incredible.
One really couldn't ask for a better author who could fittingly express the terrifying sights of the hell itself.
