"Two heavy trestles, and a board
Where Sato's gift, a changeless sword,
By pen and paper lies,
That it may moralise
My days out of their aimlessness.
A bit of an embroidered dress
Covers its wooden sheath.
Chaucer had not drawn breath
When it was forged. In Sato's house,
Curved like new moon, moon-luminous,
It lay five hundred years.
Yet if no change appears
No moon; only an aching heart
Conceives a changeless work of art. "
From Meditations in Time of Civil War W.B.Yeats
