Rhetrae
(
ῥῆτραι). Specially the name of the ordinances of
Lycurgus. The word
ῥῆτρα means a solemn compact, either
originally emanating from or subsequently sanctioned by the gods, who are always parties to
such agreements. The rhetrae of Lycurgus emanated from the Delphian god; but the kings,
senators, and people all bound themselves, both to each other and to the gods, to obey them.
Plutarch mentions four rhetrae (
Lyc. 6 and 13), and describes them as relating to (
a) the building of a temple to Zeus and Athené (
b) the
division of the people into
φυλαί and
ὠβαί; (
c) the establishment of the Senate (
γερουσία); and (
d) the assemblage of the
people at the time of the full moon.
