revolution_fr | Pasternak's Robespierre/Saint-Just play

Hi all - salut et fraternite! I've only just joined livejournal and this is my first posting here, so apologies if I mess this up (what's an ljcut?) - anyway, my question: I've always thought the character Pasha/Strelnikov in Pasternak's 'Dr. Zhivago' owed more to Robespierre and co. than to Lenin or Trotsky, and not just cos of the little round glasses, so I googled it and it turns out that Pasternak wrote some fragmentary verse plays about Robespierre and Saint-Just in 1917, published in a magazine in 1918 - apparently, as with Stani, they were inspired by Buchner - and they partly formed the basis for the themes in 'Zhivago'. That's all I know - is there anyone out there who can tell me any more?
