Four conjectural plans of the Forum, Rome, titled 'Bunsen', 'Canina', 'Becker' and 'Dyer'

NOTES: These plans appear to show the same site in four different conjectural reconstructions and probably refer to the restoration work of the 19th century archaeologists Baron Christian von Bunsen, Luigi Canina, Wilhelm Alfred Becker and (Thomas H. ?) Dyer.
