Map of ancient Attica as it was shaped after Cleisthenes' reforms. Some of the demes are indicated with a black dot; the broken line shows the boundaries of the trittyes. The numbers in the trittyes display the tribes to which each of them belonged. Christopoulos, G., Bastias, J., Istoria tou Ellinikou Ethnous, vol.3/1, Ekdotiki Athinon, Athens 1972, p. 83.
