I puritani in the context of "Cavalier"

Aquatint is an intaglio printmaking technique, a variant of etching that produces areas of tone rather than lines. For this reason it has mostly been used in conjunction with etching, to give both lines and shaded tone. It has also been used historically to print in colour, both by printing with multiple plates in different colours, and by making monochrome prints that were then hand-coloured with watercolour. The term colour etching, frequently used in the art trade, is potentially ambiguous, but most often means one of these two options.

It has been in regular use since the later 18th century, and was most widely used between about 1770 and 1830, when it was used both for artistic prints and decorative ones. After about 1830 it lost ground to lithography and other techniques. There have been periodic revivals among artists since then. An aquatint plate wears out relatively quickly, and is less easily reworked than other intaglio plates. Many of Goya's plates were reprinted too often posthumously, giving very poor impressions.

Monochrome printmaking is a generic term for any printmaking technique that produces only shades of a single color. While the term may include ordinary printing with only two colors — "ink" and "no ink" — it usually implies the ability to produce several intermediate colors between those two extremes.

In contrast with color printing, monochrome printing needs only a single ink and may require only a single pass of the paper through the printing press.

Count Carlo Pepoli (22 July 1796 – 7 December 1881) was an Italian politician and journalist. He was also acclaimed as a poet, his most well-known work being the libretto for Vincenzo Bellini's final opera, I puritani which was given its premiere in Paris in January 1835.

Born in Bologna to the aristocratic Pepoli family, he was active in the movement opposing Austrian rule of Italy before being imprisoned and forced into exile in France after 1831. He spent a large portion of his adult life as an exile in both Paris, where he initially taught Italian. He also lived in England, where between 1839 and 1848, he was "Professore di Letteratura italiana" at University College, London. He returned to Italy briefly in 1848, then from 1859 resumed his political activities which continued to within a year of his death which took place in 1881 in his native city at the age of 85.
