How did Roman law perceive the distinction between freedom and enslavement? While initially stark, this division was permeable, allowing individuals to transition between statuses. This talk delves into the fluidity of this line, focusing on gratitude and obligation, particularly the concept of the "ungrateful freedperson." Despite cultural assumptions that freed individuals owed perpetual gratitude to their former masters, Roman law empowered patrons to charge ingratitude, leading to various penalties, even re-enslavement. The dynamics were most apparent in marriages between freedwomen and their patrons, shedding light on Roman notions of liberty and enslavement.
