Les Eaux douces d'Europe. Európa édesvizei, Konstantinápoly.

Postcard of the sweet waters of Europe in Constantinople (Istanbul), Turkey. Constantinople (Greek: Κωνσταντινούπολις, translit. Kōnstantinoúpolis; Latin: Cōnstantīnopolis) was the capital city of the Roman/Byzantine Empire (330–1204 and 1261–1453), and also of the brief Crusader state known as the Latin Empire (1204–1261), until finally falling to the Ottoman (1453–1923) empire. It was reinaugurated in 324 from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, and dedicated on 11 May 330. The city was located in what is now Istanbul in Turkey.
