Ostracismus
（
ὀστρακισμός, i. e. vote by potsherd,
ὄστρακον). A mode of judgment by the people practised in various
Greek States (Argos, Megara, Miletus), and especially at Athens, by which persons whose
presence appeared dangerous to liberty were banished for a certain period, without, however,
thereby suffering any loss in reputation or property. Ostracism was introduced at Athens in
B.C. 509. It was applied (among others) to Themistocles, Aristides, Cimon, and Alcibiades, and
was last exercised in 417 against a demagogue, one Hyberbolus, whose insignificance made the
measure ridiculous, and so brought about its abolition (
Thuc.viii.
73;
Nicias, 11,
Alcibiades, 13). Every year the question
was put to the people, whether the measure appeared necessary: if they so decided (and it was
only exceptionally that there was occasion for it), the citizens who possessed the franchise
assembled in the marketplace, and each wrote upon a sherd (
ὄστρακον) the name of the person whose banishment he deemed desirable. The man
whose name was found upon not less than 6000 sherds had to leave the country in ten days at
latest, for ten or (later) five years. He could, however, at any time be recalled by a decree
of the people; and the question, as before, was decided by not less than 6000 votes. (See
