Leaves from a 1557 devotional book made for the head of the Neapolitan church which was one of the four manuscripts recovered by Art Recovery International.
A group of illuminated manuscripts valued at £100,000 that was stolen from a London auction house in 2016 has been recovered in Italy.
The theft took place in an early morning raid in Mayfair where thieves scaled the walls of an adjoining building and entered through a window.
