Kairos -

Who and whence was the sculptor? 
From Sikyon.

And his name? 
Lysippos.

And who are you? 
Time who subdues all things.

Why do you stand on tip-toe? 
I am ever running.

And why you have a pair of wings on your feet? 
I fly with the wind.

And why do you hold a razor in your right hand? 
As a sign to men that I am sharper than any sharp edge.

And why does your hair hang over your face? 
For him who meets me to take me by the forelock.

And why, in Heaven's name, is the back of your head bald? 
Because none whom I have once raced by on my winged feet will now, though he wishes it sore, take hold of me from behind.

Why did the artist fashion you? 
For your sake, stranger, and he set me up in the porch as a lesson.
