Could you help me to correct a sentence, please?

Here it is:

«The first of them (of the four statues) depicted supercilious and ruinous Unbelief, the other — dark and as well harmful Superstition, the third showed their father — hardened and stubborn Ignorance, the fourth — their loathsome child — fierce and insensitive Inhumanity.»

That's how I translated it from Russian.

Thanks for help, Rose!

It's from Mikhail Popov's "Chronicle of Violent Miracles (literally, magicks)" written in 1760s... You see, I can't translate the title well...

The only question I have is about the "as well" phrase that you have stricken out. In the original, it meant that Superstition was as harmful as previously mentioned Unbelief. And I tried to keep to the structure of the original text. How can I express that?

And, I guess, it should be Disbelief. I am not sure though (could not get the differnce from thefreedictionary...). Would you please tell me how the two words differ?

How fantastic!  I'm going to search for a translation, as the title has really grabbed me!

In terms of expressing the 'as well', I suppose you might use something like "similarly harmful" or "just as harmful" - but both of these are going to make your sentence a bit clunky, and the latter is a bit too informal for the context IMO.

For me, the difference between Unbelief and Disbelief would be pretty subtle.  While Disbelief implies that you have heard the truth and refuse to believe it, Unbelief (a word that is not typically used, but etymologically plausible) would suggest you have never heard the truth - closer to ignorance than to rejecting the truth.

«I'm going to search for a translation...»

I am afraid you won't find one. So, the only thing left for you is to die of envy (smile here).

«I suppose you might use something "just as harmful"»

What about "as harmful" and "equally harmful"? Won't make sense?

P.S.: Would you let me know if you find a translation nevertheless...
