This room on the second floor of the Teresian library, towards the end of the corridor on the left, was very probably used for religious purposes, as attested by the frescoes that decorate it. Perhaps this was the so-called Oratorio delle Scuole inferiori The frescoes depicting scenes from the life of Christ, have been attributed by Stefano L'Occaso, although it is not possible to prove this with certainty, to the late Baroque painter Siro Baroni, who lived and worked in Mantua, and whose works can be admired in the churches of Santa Barbara and Sant'Orsola.
