I'm trying my best to see this from a female perspective, and failing badly
So to me, Gabriel's POV would work best, but only because it would give me (if I were the writer) the chance to explore his thinking on art (which totally dominated his approach to life & love, in my opinion).
Oh, I totally agree. Rossetti's character is far more interesting. Lizzie's life story, though - world's first supermodel, rags-to-riches, etc. - is more interesting. (That does not a work of fiction make, of course.) An upper-middle class artist ruining his life? Well, THAT'S never been covered before, lol. But the
manner in which Rossetti totally screwed up his life is fascinating.
The fact that Rossetti was responsible for his own undoing, while Lizzie was mostly NOT responsible for hers, makes his a far better POV and lays out a character arc that is clear as day.
To my (admittedly biased) eyes, Lizzie's POV would be unrelentingly upsetting (her story genuinely is a tragedy, I think)
Bingo.
and I can't help but see her as a less interesting character than Gabriel. But as I wrote, this may be a naturally 'predjudiced' opinion, given the fact that I'm male & fascinated by Gabriel's mindset.
I find her really interesting simply because 1) when I was young, I always wondered about the models in the pre-Raphaelite paintings and if they were all the same woman; turns out, they are! (Not entirely, but you get my drift.) And 2) she was the first (that I know of) model in art that was really like
a supermodel as we think of them today, rather than, well, a prostitute or something.
If you had to sum each up in twenty-five words or less, Siddal sounds more interesting, basically. Rossetti had the most interesting persona, totally.
I think that I'm the one with gender bias, not you.
I think the people attracted to fiction on similar subjects (like the books by Tracy Chevalier) are largely women, also.
I should qualify the above: I don't in any way see Gabriel as a hero - his behaviour towards Lizzie was appalling, whether deliberate or otherwise - I just find his inherent rejection of the real world, real emotions in favour of a 'dreamworld' very interesting.
His life became a tragedy because of his otherworldliness - many mid-to-late Victorian artists portrayed women as lifeless, vulnerable (whether in death, or in repose) yet Gabriel's tragedy was a self-fulfilling prophecy - unlike the other artists, his art was real to him...much to his eventual cost (and Lizzie's, of course.)
I totally get it. Behaving badly is always way more interesting than behaving well, for one thing. And the way that Rossetti behaved badly is good stuff, and by good I mean compelling.
