This paper aims to analyze the political importance of divine inspiration for Spartan and Roman
political reforms carried out by Lycurgus (c. 650 BC?) and by Numa Pompilius (715-673 BC).
In the former case, the constitution is supposed to have been transmitted to Lycurgus by the
Delphic oracle and consequently it was called Rhetra, a “ceremonial utterance” or an “agreement”
(Lyc. 6). Similarly, in the Life of the Roman counterpart, the goddess Egeria (Num. 4.2) inspires
the second king of Rome to carry out a profound religious reform. In fact, this is not a specific
feature of these Lives, since several other lawgivers were credited with divine assistance, such as
Minos, Zaleucus or Zoroaster. The discussion of this issue is designed to reveal the argument
that may lie behind these legends: divine inspiration or an artificial way of legitimating the
lawgiver’s power? In fact, despite all the effort made in order to sacralise these ancient political
institutions, Plutarch himself seems to accept the latter theory. This strategy can be seen as a kind
of political lie which had previously been accepted by Plato as an instrument for legitimizing
constitutional reforms (R. 389b).
