Help me find the author to this quote

I heard this quote used in a song and i cant find who wrote it (i don’t think the musicians themselves created it)

“Remember with pride what thou art, lest we forget in awe of our terrible past.”


Cradle of Filth - “The Rape & Ruin of Angels”

Yeah, thats where i heard it, however in the lyrics its in quotes, so i thought he was quoting an author.

Oh, oops!
I looked in a few of my quotation anthologies and couldn’t find it…
