In 1789, supported by the hereditary Prince of Coburg-Gotha, he got a grant from the Margrave of Ansbach-Bayreuth, and, aged 28, he left Dresden and moved to Rome.
Reinhart came under the influence of the classicist German painters Asmus Jacob Carstens and Koch and became a conspicuous exponent of the historic landscape.
[1] His paintings, drawings and etchings, of which he made many prints, brought him artistic recognition and financial success and he was eventually able to support a family.
In 1829 he was asked by the future King Ludwig I of Bavaria to paint the view of Rome to the north, the south, the east and the west of the royal villa, high up on the Pincio.
[citation needed] His best known work is represented by the "Eight Historic Landscapes" (1825), in the Palazzo Massimi, Rome, and "Four Views from Villa Malta," in tempera, painted for King Ludwig I of Bavaria.
