At the request of Pope Paul IV, he prepared over fifteen years a systematic institutional treatment of canon law, following the model of Justinian’s *Institutiones*, divided into four books: *De personis*, *De rebus*, *De iudiciis civilibus*, *De iudiciis criminalibus*. However, since he did not receive papal approval for certain theories that displeased the specially delegated commission, he published the work at his own expense in a private edition in 1563.

LANE TERZI, FRANCESCO. - A ship capable of moving through the air by means of oars and sails. A.B.C.D.: Four hollow spheres devoid of air. F.E.: wooden boat with sail. Copper engraving – Copy in the Library of the Civiltà Cattolica.
He proposed the possibility of constructing “a ship that can travel through the air by oars and sails,” and provided its illustration, description, and the scientific principles on which it was based. The news aroused much admiration (Fr. B. Zamagna composed a poem about it: *Navis aerea et elegiarum monobiblos* [Rome 1768]) and also controversy. It is not certain whether L. T. actually built his ship in practice, nor whether, having built it, he conducted an experiment with it; yet he still merits the credit for having posed the problem and, among the first, for having sought to solve it scientifically. Other inventions by L. T. include a new method for the blind to read, improvements to the microscope and telescope, etc.
