This, in the case of the trierarchy, would be the aggregate amount of the valuations of the 1,200 wealthiest men, viz. 6,000 talents. (Of course the capital taxable for the war-tax would be considerably larger. Even at a time when the prosperity of Attica was much lower, in 378-377 B.C., it was nearly 6,000 talents, according to Polybius, ii. 62. 6.)
