Giuseppe Cesari
Over a decade before, Cardinal Matthieu Cointerel (in Italian, Matteo Contarelli) had left in his will funds and specific instructions for the decoration of a chapel based on themes related to his namesake, St Matthew. The dome of the chapel was decorated with frescoes by the late Mannerist artist Giuseppe Cesari, Caravaggio's former employer and one of the most popular painters in Rome at the time. But as Cesari became busy with royal and papal patronage, Cardinal Francesco Del Monte, Caravaggio's patron and also the prefect of the Fabbrica of St Peter's (the Vatican office for Church property), intervened to obtain for Caravaggio his first major church commission and his first painting with more than a handful of figures.
