An Adoration of the Magi in the church of Santa Maria di Colle, signed and dated 1717, is the earliest of Boccanera's works presently known.
It is marked by a casual eclecticism absent from works features of his master Giacinto Brandi as well as in Venetian style of Francesco Trevisani.
One of two altarpieces Boccanera painted for San Bernardo (current Intendenza di Finanza of Perugia) is dated 1714.
In the same warehouse was the Martyrdom of St. Giuliana, while in the church of Santo Spirito was the Baptism of the Emperor Constantius, dated 1731.
So almost at the end of his career's trajectory, he returned to recall the intrepid "attitudes" in vogue fifty years earlier in the circle of Brandi, interpreting them with that license and overabundance that would displease "classicist" Orsini.
