In trying to find a work that would feel "just right," I looked in on the Fra Angelico works at the World Gallery of Art. Among many other possibilities, I found this Sacra Conversazione, c. 1445.
I've come across that Italian phrase before but its meaning has remained a bit vague for me. Checking it out, here's one definition that I found:
sacra conversazione (It.: ‘holy conversation’). A representation of the Virgin and Child with Saints in which all the sacred personages are disposed in a single pictorial space rather than in the separate compartments of a polyptych. Usually the figures are shown silently communing rather than conversing. The type originated in Italy in the first half of the 15th century . . . .Here's another Sacra Conversazione, c. 1450, also by Fra Angelico.
