The tower is fifty ells down and the same up. There is a man kept in the dungeon under the tower. The king has bound him to his conscience with a chain. After a wonderful life he is counting days, but not waiting.
On the top of the tower lives an astronomer. The king bought him a telescope to bind him to the universe. The astronomer counts the stars, but isn't afraid. The man on the top and the man down below fall asleep full of numbers.
That's why they understand each other. They have no pigeon, but a black cat carries messages from the dungeon to the top of the tower.
- There goes another day - it says to the astronomer.
To the prisoner:
- A star was born.
All three of them have green eyes.
From the long vigil, not from hope.
Zbigniew Herbert, Tower
