There is someone else between St. Francis (stigmata) and St. Jerome. Who is he?
Albert the Great?
And I was wondering if the one before St. Dominic was St. Benedict?
I think you're right and I'm wrong. Looking at a number of images of Benedict and Bernard, most of Bernard show him without a beard, and most of those which do, don't have a 'split' beard like this.
This is Fra Angelico's
The Coronation of the Virgin, and the Web Gallery page says the saints are St Thomas, St Benedict, St Dominic, St Francis, St Peter the Martyr and St Mark.
