Zeus. A sensible proposal. Heracles, you can go too; take Philosophy with you, and lose no time. Think: this will make your thirteenth Labour, and a creditable one too, the extermination of these reptiles.

Hera. Rather than meddle with them, I would give the Augean stables a second clean-out. However, let us be starting, Philosophy.

Phi. If I must, I must.

Her. Yes, come along, and we will polish off a few to-day.—Which way, Philosophy? You know where they are to be found. Somewhere in Greece, of course?

Phi. Oh no; the few that there are in Greece are genuine philosophers. Attic poverty is not at all to the liking of the impostors; we must look for them in places where gold and silver mines abound.

Her. Straight to Thrace, then?

Hera. Yes, Thrace, and I will show you the way. I know every inch of Thrace; I have been there so often. Look here, this is our route.

Her. Yes?

Hera. You see those two magnificent mountains (the big one is Haemus, and the other Rhodope), and the fertile plain that spreads between them, running to the very foot of either? Those three grand, rugged crests that stand out so proudly yonder form as it were a triple citadel to the city that lies beneath; you can see it now, look.

Her. Superb! A queen among cities; her splendours reach us even here. And what is the great river that flows so close beneath the walls?
