Ariosto began working on the poem around 1506, when he was 32.
The first edition of the poem, in 40 cantos, was published in Ferrara in April 1516 and dedicated to the poet's patron Ippolito d'Este.
A second edition appeared in 1521 with minor revisions.

Ariosto continued to write more material for the poem and in the 1520s he produced five more cantos, marking a further development of his poetry, which he decided not to include in the final edition.
They were published after his death by his illegitimate son Virginio under the title Cinque canti and are highly regarded by some modern critics.
The third and final version of Orlando Furioso, containing 46 cantos, appeared in 1532.

Ariosto had sought stylistic advice from the humanist Pietro Bembo to give his verse the last degree of polish and this is the version known to posterity.

The first English translation by John Harington was published in 1591 at the behest of Queen Elizabeth I, who reportedly banned Harington from court until the translation was complete.
