Formaleoni V., "Storia Filosofica e Politica della navigatione, del commercio e delle colonie degli antichi nel Mar Nero", Venezia, 1788-89. First and only edition. Two volumes in 8vo, (21x13cm), pp.302+400. Contemporary leather over boards, spine richly gilt, marbled edges. Binding rubbed, edges of spines missing, one cover almost detached, hinges weak. Internally clean and fine. Complete with the big folded copper engraved map of the Black Sea, titled: "Hydrographia del Ponto Eusino" (Not in Zacharakis). The access of international trade to the Black Sea after the Russian victories, is a major issue of the late 18th century, with the Venetians starting to consider once again this profitable trade route. Formaleonis publication is bringing to the fore that issue for the Venetians, using all available sources from the ancient times through the middle ages up to the contemporary Crimean annexation and traveller accounts. This officially promoted publication is one of the last examples of the Venetian State entrepreneurship. The Black sea is presented in all its aspects (navigation, commercial, history, ethnology). Not in Atabey or Blackmer. Very rare.
