In the summer of 1667, and following completion of the Falconieri chapel (the High Altar chapel) in San Giovanni dei Fiorentini, Borromini committed suicide in Rome,[REF] possibly as a result of nervous disorders and depression.
In his testament, Borromini wrote that he did not want any name on his burial and expressed the desire to be buried in the tomb of his kinsman Carlo Maderno in San Giovanni dei Fiorentini.
