[The poem in which he revealed the secret of solving the cubic to Cardan]

When the cube and the things together

Are equal to some discrete number,

Find two other numbers differing in this one.

Then you will keep this as a habit

That their product shall always be equal

Exactly to the cube of a third of the things.

The remainder then as a general rule

Of their cube roots subtracted

Will be equal to your principal thing.
