[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. ^{***}
^{*} [Solve x^{3} + cx = d]
^{**} [Find u, v such that u  v = d and uv = (c/3)^{3} ]
^{***} [Then x = ^{3}√u  ^{3}√v ]
