Muller made a tour to the continent in 1834 with his friend and fellow painter, George Arthur Fripp (1813–1895). An account of the journey is given in Solly's biography, based on information provided by Fripp, who said of Muller that 'he never knew so pleasant a fellow to travel with... he possessed such a vein of humour and so much observation, that he had something amusing or witty to say on every passing event.'1
The pair travelled through Belgium, Germany and Switzerland before staying in Venice for two months. They arrived in Florence on 27 November and remained only a few days before continuing to Rome. Though Solly records that there was little time for sketching in the city, 'A Large Picture of Florence' is recorded among his 'Principal Oil-Pictures.'2
