A loaf of bread cost a quarter of a sesterce. So did a glass of wine.2 We know from graffiti at Pompeii that a prostitute, perhaps not a very elegant one, charged half a sesterce for her services. Entrance to the public baths was just twice that. Roman soldiers earned 1,200 sesterces a year and although there were some perks, they had to buy their own equipment. A casual labourer earned perhaps 2-3 sesterces a day – when he got work. A charity scheme to support poor children, presumably at a fairly basic level, paid between 10 and 12 sesterces a month. A lecturer in rhetoric under Vespasian received 100,000 sesterces a year and this was considered remarkable. It was a similar amount to the purchase price of a first-rate, intelligent slave in the second century, when lessening warfare had reduced the market. One foot of road cost 22 sesterces to lay and a large and elaborate tomb anything from 100,000 to half a million sesterces.
