Fundamental to an understanding of the Roman Republic is comprehension of the tribal system employed to organise citizens. In this volume, first published in 1960, evidence is adduced to locate and describe the tribes' locations. In his major new update, Lily Ross Taylor's disciple and scholarly follower Jerzy Linderski brings forward new evidence resolving earlier cruces, updates the lengthy bibliography on voting districts, and situates this invaluable work in its historical perspective.
