The saints are from left to right: Mark, Peter Martyr, Thomas Aquinas, Dominic, Luke; and to the right of the figures of the Virgin and Child: John the Evangelist, Gregory, Catherine of Alexandria, the Magdalen, and a bishop with a book (perhaps Thomas à Becket).
The painting is associated with the Dominican Church of S. Maria Novella in Florence because of the artist's links with this church and the choice of saints, some of whom are Dominican, and all of whom had altars dedicated to them in the church.
