This is a beautiful example of Alexandre Delamarche's 1845 map of europe under the Roman empire from the time of Augustus Caesar to the signing of the peace treaty between emperor Diocletian and the Sassanid King Narseh. It covers all of europe from the Atlantic Ocean to Asia, and from the Arctic to northern Africa showing the extent of the Roman empire at its height, including most of europe, the Middle east, Persia and parts of north Africa.The empire was established in 27 BC after Gaius Julius Caesar Octavianus, the grandnephew and heir of Julius Caesar was awarded the honorific title of Augustus. During the time of the empire, Roman cities flourished with a global trade network spread as far as India, Russia, China and Southeast Asia. However, the sheer size of the empire and its success also contributed to its downfall. The Western Roman empire collapsed in AD 476, when Romulus Augustulus was deposed by the German Odovacer. The eastern Roman empire, evolving into the Byzantine empire, survived until the Ottoman Turks captured Constantinople in 1453.Throughout, the map identifies various cities, towns, rivers, mountain passes and an assortment of additional topographical details. Political and regional borders are highlighted in outline color. This map was issued by Delamarche as plate no. 15 in his Atlas Delamarche Geographie Modern.
