[San Felipe ?- Rossi Giovanni Giacomo], "Citta di Scio", no place or date, but Roma, 1694. Extremely rare, separately issued, impressive copper engraved map (53x19,5cm) of the town of Chios. This independent, beautiful and accurate map of Chios is, probably one of the rarest and important maps of the island ever published (Not included in P. Argenti collection). Although Zacharakis reports its joint state (827, under Cantelli) published in "Teatro della guerra contro il Turco", we suggest an alternative author based on the following. Firstly, the general date in use 1687-91 (date of death of Giacomo Rossi) does not seem reasonable, as the map is precisely accurate presenting details of the road network that presuppose measurements on the field, and this kind of field-work could not be made before the short Venetian occupation of the island in 1694-95. Secondly, the "Teatro..." is a collection of views of the conquered by the Christian Armies towns and that is not the case for the, 1687-91 still under Ottoman rule, Chios. It is most possible that the map has been published in late 1694 to celebrate the liberation of the island. As it is extremely accurate, it could be suggested that it has been drawn by the Venetian engineers - cartographers that took active part in the operations. In this frame the cartographer could be San Felipe who was the chief of engineers and had also designed maps during the war operations. We suggest that the map was jointed with Lefkada map, as they were the two only islands liberated (outside Morea) for a victorious publication in Roma, probably by the son of Rossi, Lorenzo who had the other plates. As the Turcs reoccupied Chios in 1695, the celebrations and publications were of short time and the map is Extremely Rare.
