What is it with guys and squeamishness about female body parts anyway? Okay, so it's not human, but why gross other than in a large way?
I agree it's beautiful and strange. The creature, however alien, is serving a caring function, of humans in this case... but... not entirely useless to the Mythos: http://leadadventureforum.com/index.php?topic=20326.msg291860#new
I dunno... to my mind female anatomy, even in it's minutia, is beautiful, and I tend to find those who find it grotesque to be quite alien, but to me this looks like the sculptor himself, whether he succeeded or not, was meaning for this to be received as grotesque.
I may not see it that way, but I can see that
he was seeing that way, if you see what I mean.
And that "caring function" idea is a big WTF, since one of the women is manacled, and another is, in the sculptor own words, "fear stricken". I mean, you could say it cares for it's offspring, but aside from that it's obviously a rape monster.
I also agree with Anatoli Re: the oddly inconsistent quality of the sculpt.
I do agree though that it's anything but useless to the mythos. Lovecraft conspicuously avoided direct sexuality, but humans interbreeding with otherworldly beings and monsters, sometimes consensually, but far from always, is a strongly recurring theme. And even beyond that, there are a number of creatures in the mythos for whom Mengele-ish reproductive experiments would be quite plausibly in character.
