“Ponte Salaro” Ponte Salaro was named after Via Salaria, the road through which the inland regions north of Rome (such as Sabina) received the salt they needed for food preservation and cheese production. Ponte Salaro crossed the Aniene near the point where this river flows into the Tiber; many foreign painters of the 17th and 18th centuries depicted it in their Italianate landscapes, small oil paintings which they sold in their countries of origin; similar to them Giuseppe Vasi gave more relevance to the landscape than to the bridge in this 1754 etching; for a very different approach, see a view by Giovanni Battista Piranesi (1720-1778) drawn at approximately the same time. Vasi, Giuseppe Corleone, Sicily, August 27, 1710 ?? Rome, April 16, 1782 Italian engraver and architect, best known for his vedute. The first series of akin consists in the “Vedute di Roma sul Tevere” (Views of the Tiber), circa 1743, and later adapted to become part of the “Delle magnificenze antica e moderna di Roma”. In these years, Vasi also hosted in his workshop for a limited period of time the young Giovanni Battista Piranesi (Mogliano Veneto, 1720 ?? Rome, 1778), his major pupil, who shaped here his technique as an engraver. From 1747 to 1761, he published a series of ten volumes including circa 240 engravings of view of Rome. These two watches are the only two known to date whose decor is made in micro-mosaic. These pieces are most probably the object of an order for the Italian market and / or intended for a member of a patrician family of the Roman nobility because it is in Rome that flourished at the end of the 18th century the art of the micro-mosaic. The attribution to the workshop of Louis Decombaz results from a watch whose “souscription”-type movement is signed by him (private collection). If the name of Louis Decombaz is today forgotten, it is necessary to know that it is at the beginning of the 19th century the privileged contact in Geneva of Abraham-Louis Breguet (1747-1823) and that it is he who realizes for the Parisian master watches with mechanisms of Grande and Petite Sonnerie, often made for the Turkish market, whose cases are decorated with Genevan enamels. Decombaz is one of the best watchmakers in Geneva of his time.
