352
Year 352 (CCCLII) was a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Decentius and Paulus (or, less frequently, year 1105 Ab urbe condita). The denomination 352 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events 
 By place 
 Roman Empire 
 Emperor Constantius II invades northern Italy in pursuit of the usurper Magnus Magnentius, who withdraws with his army to Gaul. He declares an amnesty for Magnentius' soldiers, many of whom desert to him. By the end of the year Constantius enters Milan. The Alamanni and the Franks cross the Rhine and defeat the depleted Roman units left at the frontier. The Germans take control of around 40 towns and cities between the Moselle and the Rhine. Constantius Gallus sends his general (magister equitum) Ursicinus to forcefully put down the Jewish revolt in Palestine. The rebels destroy the cities Diopolis and Tiberias, while Diocesarea is razed to the ground. Ursicinus gives the order to kill thousands of Jews, even children. After the revolt, a permanent garrison is stationed in Galilee. Asia
