The Brothers Eberhard, 1822. In 1822, Johann Anton Ramboux accompanied the Eberhard brothers to Munich, where he executed this double portrait lithograph. Because he intended the print to be a gift to the sitters, only a small number of impressions were produced. This exceedingly rare work is an exquisite example of early German lithography, a technique which had only been invented in 1798. Ramboux, who had been a student of the French painter Jacques Louis David (1748-1825), lived in Rome between 1816 and 1822. There he befriended a group of German artists who had formed the Brotherhood of St. Luke (also called the Nazarenes). They inhabited a deserted monastery and lived a life of study and Christian devotion. Their art strove to restore the pious purity of early 16th-century Italian and German painting, emulating the strong draftsmanship of Raphael (1483-1520) and Albrecht D?rer (1471-1528). Such an emphasis on skillful drawing is evident in this lithograph: Ramboux beautifully modeled the two heads in light and shade.
