Copper engraving, mm 455x1000. From “Nouveau Theatre d’Italie”. Stunning bird-eye view of the city taken from the sea. Mortier, active in Amsterdam at the beginning of the century, republished Blaeu's “Theatrum Civitatum…Italiae”, originally printed in 1663 adding a fourth volume, related to Tuscany and northern Italy. Very good example, large margins, original folds with some restoration at two of them
