I'm pretty sure this comes from an English poem, referring a woman's beauty. The author suggests that roses fade and wither, and that by describing her in written word keeps her alive forever.
That might be a misdirect, it was a long time ago I read it. The actual poem didn't really stick with me, but the last line did and I've been trying to find the origin:
Immortalised in prose, a god among the pages
