Pars prima (Sicut..hominis) from Grande Chartreuse 808 (saec. 14) cf. table 533 of the Solesmes Paleo. Pars altera from Plantin, with rectified adaptations based on Sandhofe. Standard verse with a more reasonable structure than Sandhofe's given the grammar. TODO: this R is apparently in the Rouen proper (as noted on the Solesmes Paleo table): find it.
