The Roman emperor Marcus Aurelius Probus (232-282) secured the Rhine and Danube lines in his battles against the Franks, Alemanni, Burgundians, Vandals and Goths. In 280, he lifted the ban imposed by Emperor Domitian (51-96) in 92 on planting vines in the provinces outside Italy. In the "Historia Augusta" it is mentioned: Gallis omnibus et Hispanis ac Brittannis hinc permisit, ut vites haberent vinumque conficerent (He allowed all Gauls, Spaniards and Britons to own vines and to produce wine). In Germany and Austria, he is considered to be the founder of viticulture and is even brought close to wine gods. In the wine tavern village Grinzing in Wien there is even a lane named after him, but the emperor probably never visited this former Roman border settlement. Although he gave important impulses, his achievements have been somewhat exaggerated, for example by the French chemist Jean-Antoine Chaptal (1756-1832). However, it is undisputed that he positively influenced viticulture all over Europe.
