How much did food cost in ancient Greece?

Answer 1

A loaf of bread would be 1 obol (a type of coin in ancient greek times). A lamb would be 8 drechmas (another type of coin in ancient greek). A pork steak would be around 1 drachmas and a gallon of olive oil would be 5 drachmas.

Answer 2

It varied over the centuries as inflation pushed prices up. In Athens in the 5th Century BCE a state slave was paid a subsistence allowance of 4 obols a day; a citizen juryman 3 obols; an artisal six obols (six obols to the drachma). Some estimate half of income was spent on food.
