550-563 But I will tell you another thing, Son of all-glorious
Maia and Zeus who holds the aegis, luck-bringing genius of the gods.
There are certain holy ones, sisters born--three virgins gifted
with wings: their heads are besprinkled with white meal, and they dwell
under a ridge of Parnassus. These are teachers of divination apart from
me, the art which I practised while yet a boy following herds, though my
father paid no heed to it. From their home they fly now here, now there,
feeding on honey-comb and bringing all things to pass. And when they are
inspired through eating yellow honey, they are willing to speak truth;
but if they be deprived of the gods’ sweet food, then they speak
falsely, as they swarm in and out together.
