J. H. W. Tischbein. Goethe in the Italian countryside, 1787. Oil on canvas. 164 x 206 cm. Frankfurt, Städelisches Kunstinstitut.
Requeno's treatise raised in Rome an enthusiasm and controversy similar to those produced in Paris by the experiments of Caylus. Requeno found in J. F. Reiffenstein, counselor to the Empress Catherine II, a passionate promoter of his ideas. Reiffenstein transformed his Roman residence into a workshop of encaustic painting, accurately described by Goethe in his "Italian Journey".
