A study from a model in Dominican robes reading a book, for the figure of St Dominic in Reni's huge Madonna della Pietà (or Pietà dei Mendicanti), painted as the high altar of the Chiesa dei Mendicanti in Bologna and now in the Pinacoteca. 

Three further drawings for the composition are in the Palazzo Rosso, Genoa, one of which is inscribed by Reni with the date 13 November 1613, establishing that Reni was then working on the design (though he was still in Rome at that date). The painting was installed in the church by November 1616. Two further studies for the painting are at RCIN 903355 and 903364.
