4thly. A protection tax [277], paid by the settlers, or Metoeci,

Athens from the number of strangers that her trade, her festivals, and
her renown attracted. The policy of Pericles could not fail to
increase this source of revenue.

5thly. A slave tax of three obols per head. [278]

Most of these taxes appear to have been farmed out.

6thly. Judicial fees and fines. As we have seen that the allies in
most important trials were compelled to seek justice in Athens, this,

great value to the state. Sometimes (as in all private accusations)
the fine fell to the plaintiff, sometimes a considerable proportion
enriched the treasury of the tutelary goddess. The task of assessing
the fines was odious, and negligently performed by the authorities,
while it was easy for those interested to render a false account of
