Roman lamp question

[D B Campbell]

Does this look right? Did they have matches?

Yes, it seems to be correct. I must confess that I assumed the Romans used flint-and-steel, although Theophrastus (the "wood" guy) talks about the kind of fire-drill that Boy Scouts use. But you're right -- Martial has certainly been cited as evidence of sulphur matches, sulphurata. (He seems to be the only one, though.)
