Slavery was a very common practice in Ancient Greece, as in other places of the time.
Slave labour was prevalent in mines and quarries, which had large slave populations, often leased out by rich private citizens.
The strategos Nicias leased a thousand slaves to the silver mines of Laurium in Attica; Hipponicos, 600; and Philomidès, 300.
It is difficult to estimate the number of slaves in ancient Greece, given the lack of a precise census and variations in definitions during that era.
It is certain that Athens had the largest slave population, with as many as 80,000 in the 6th and 5th centuries BC, on average three or four slaves per household.
The domestic's main role was to stand in for his master at his trade and to accompany him on trips. The female slave carried out domestic tasks, in particular bread baking and textile making.
