Eicosté
(
εἰκοστή). A customs duty of one-twentieth (five per
cent.) upon all commodities exported or imported by sea in the States of the allies subject to
Athens. This tax was first imposed in B.C. 413-412, in the place of the direct tribute
(
φόρος) which had up to this time been paid by the subject
allies; and the change was made with the hope of raising a greater revenue (
Thuc.vii. 28). This tax, like so many others, was farmed, and the
farmers of it were called
εἰκοστολόγοι.
