In Republican age (as well in Imperial Rome) the Caelian Hill was a fashionable residential district and the site of residences of the wealthy. A section of Pliny the Elder's "Natural History", "Who Was the First to Encrust the Walls of Houses at Rome with Marble", attests to this. Mamurra, a soldier who served under Julius Caesar in Gaul and profited tremendously from corruption, achieved this expensive feat on the Caelian Hill; Horace and Catullus mocked him accordingly.
