Liberti, Libertini

Lat in Rom-an law. Freedman. There seems to have been some difference in the use of these two words; the former denoting the manumitted slaves considered in their relations with their former master, who was now called their “patron;” the latter term describing the status of the same persons in the general social economy of Rome
