The translation must have appealed to DGR because its subject matter, and especially its
tone and attitude, reflect DGR's mordant judgments on his own world and time. See for example
Poeti

As with most of DGR's translations, this one cannot be exactly fixed. It is probably a fairly early work, however—done in the late 1840s.
The translation was first published in 1861 in
The
Early Italian Poets
