"In this useful contribution, Rachel Zelnick-Abramovitz, the author of a very important monograph on Greek freedmen, re-examines the Thessalian manumission records in the light of comparative evidence from other areas, in order to establish the nature of this sum paid by Thessalian freedmen: did it constitute a manumission tax, or was it a fee for registering the manumissions? In the process, she examines various aspects of Thessalian slavery and its political, economic and social history." Kostas Vlassopoulos, Bryn Mawr Classical Review 2014.08.35.
