Lucian De Sacrificiis 2

[2] The Ethiopians, on the other hand, may well be called happy and thrice-blessed, if Zeus is really paying them back for the kindness that they showed him in dining him for twelve days running, and that too when he brought along the other gods!

So nothing, it seems, that they do is done without compensation. They sell men their blessings, and one can buy from them health, it may be, for a calf, wealth for four oxen, a royal throne for a hundred, a safe return from Troy to Pylos for nine bulls, and a fair voyage from Aulis to Troy for a_king’s daughter! Hecuba, you know, purchased temporary immunity for Troy from Athena for twelve oxen and a frock. One may imagine, too, that they have many things on sale for the price of a cock or a wreath or nothing more than incense.

[2] Those Ethiopians, too; privileged, thrice-happy mortals! Zeus, one supposes, is not unmindful of the handsome manner in which they entertained him and all his family for twelve daysrunning. With the Gods, clearly, nothing goes for nothing. Each blessing has its price. Health is to be had, say, for a calf; wealth, for a couple of yoke of oxen; a kingdom, for a hecatomb. A safe conduct from Troy to Pylos has fetched as much as nine bulls, and a passage from Aulis to Troy has been quoted at a princess, For six yoke of oxen and a robe, Athene sold Hecuba a reprieve for Troy; and it is to be presumed that a cock, a garland, a handful of frankincense, will each buy something.
