Note 680 — Chapter VI · LAWS AND DISCIPLINE OF LYKURGUS AT SPARTA.
Reading edition
How offensive the Lacedæmonian xenêlasy or expulsion of strangers appeared in Greece, we may see from the speeches of Periklês in Thucydidês (i. 144; ii. 39). Compare Xenophon, Rep. Lac. xiv. 4; Plutarch, Agis, c. 10; Lykurgus, c. 27; Plato, Protagoras, p. 348.
No Spartan left the country without permission: Isokratês, Orat. xi. (Busiris), p. 225; Xenoph. ut sup.
Both these regulations became much relaxed after the close of the Peloponnesian war.
