Daguerreotype by Achille Morelli. One of a series of topographical and architectural views which are among the earliest known photographs of Italy. Alexander J Ellis (1814-1890) wanted to use the works of Achille Morelli and Lorenzo Suscipi to augment his proposed publication called 'Italy Daguerreotyped'. The daguerreotype process was one of two pioneering photographic processes announced in 1839. Each image is a direct positive produced on sensitised metal plates in a long and complex procedure.
