Francesco Antonio Picchiatti

Francesco Antonio lived nearly all his life in Naples and worked for various Spanish viceroys.

He helped build, and with his father design, the circular church of Pio Monte della Misericordia, which contains Caravaggio's The Seven Works of Mercy.

Picchiatti was so intent on preserving and cataloging remnants of the original Greco-Roman city beneath the construction site that the work on the spire itself was eventually suspended and wasn't resumed until many years later.

It was demolished in 1900 to make room for the new Polyclinic hospital; a small section was left standing as an historical marker.

He also help design the cloister attached to the church of San Domenico Maggiore; when he died, the work was continued by his younger colleague Giovan Battista Nauclerio.
