Impressive 90x62cm, separately printed sea chart of the Greek Archipelago and eastern Mediterranean. Two more inset maps, 25x20cm each, of Greek ports in the Aegean, chartered in 1790 and 1803. Light marginal water stain, few spotting, but overall in very good condition, almost fine for a chart obviously heavenly used at sea. Spanish navy started to conduct surveys in the Aegean in late 1780s. In the following years the Spanish Hydrographic service focused, for the first time, in the Eastern Mediterranean and several manuscript charts were prepared, with unprecedented accuracy, by Galiano (1760-1805) a Spanish naval officer, cartographer and explorer who used new technology such as chronometers. It was the most advanced chart of the very early 19th century for the Greek seas. Galiano was killed in the famous naval battle of Trafalgar (October 1805) but the chart of the eastern Mediterranean was ready and published in Madrid under the Direction Hydrografica in early 1806. It is the first published Spanish nautical chart of Greek seas and includes THE FIRST EVER SPANISH PRINTED MAP OF CYPRUS (I.de Chipre). Only one copy exist in all public institutions worldwide (Madrid, Biblioteca National) and it is EXTREMELY RARE.
