“There is a season when people have the greatest need
For winds and there is a season for water from the sky,
The pouring offspring of clouds.
But if someone should ever find success through toil,
Then honey-sweet hymns form the foundation
For future tales and offer certain promise for great accomplishments.
The praise for Olympic victors is not limited
By envy. My tongue is ready to shepherd
These words. A man similarly prospers through wise thoughts
thanks to divine assistance.
Know this now, son of Arkhestratos,
Hagêsidamos: thanks to your boxing
I will sing a sweet-songed adornment
For your crown of golden olive,
Without neglecting the race of Western Lokrians.
Join us in the revel there—Muses, I pledge
That you will visit no country who rejects a guest
a people who are ignorant of noble things,
But you will find wise spearmen there.
For not even the fire-red fox nor the roaring lions
Could change the nature of their kind.”

Pindar, Olympian 11: For Hagêsidamos, Winner of Boy’s Boxing, 476 BC
