Gabrielsen's detailed study of trierarchical costs claims that in a two-month trierarchy (which he sees as the norm) the state would provide 1T while the trierarch himself would have to provide a subsidy of a further talent.(88) On Gabrielsen's assumption of sixty trierarchies taking place each year, at least 60T of private cash would have been put into circulation along with 60T of public subvention.
In addition to the trierarchy, it has been estimated that festival liturgies would have circulated another 16 or 17T each year.(89) While the trierarchy was paid for only by citizens, the festival liturgies could also involve metics.
Those tied to the festivals required their performers to finance and organize theatrical productions (the choregia), or to support and supervise the training of athletes for competition (the gymnasiarchy).(3) The naval liturgy required its performers to command and maintain a warship or trireme (the trierarchy).(4) The personal outlay could range from 1,200 to 3,000 drachmai (one-fifth to one-half a talent) for a theatrical production or athletic competition; 4,000 to 6,000 drachmai (two-thirds to one talent) for a naval command.(5) In the fourth century, citizens performing liturgies had wealth of three to four talents, or more.(6)
Thus the personal outlay for one trierarchy would approximate the life-time income of a skilled worker.
One would like to hear more about the implications of the cavalry-navy trade-off implied in exemption of the cavalry from the trierarchy, about the tactical consequences of supplementing the left of a right-wheeling phalanx with cavalry, about the implications for Athenian policy and aspirations that the Athenian democracy went into the Peloponnesian War with a strong cavalry second only to the traditional horse-breeding region of Thessaly, and about his extension of the argument of others that Xenophon served as cavalry commander to Agesilaus.
The speeches deal with a cross-section of the interests of Athenian society in the fourth century (wills, guardianship, banking, trierarchy, proxeny, slavery, citizenship) but have never been studied in a single book as a group.
Two of his speeches deal with litigation on naval affairs: the loans to Timotheos (49), trierarchy extended beyond its term (50).
51.11 a fee of 30 minas is cited; to this, of course, must be added the cost of the trierarchy, but this could be held to a minimum by the use of gear and rowers furnished by the state (cf.
