The style used by Cozens before he finally settled in Britain may be seen in a collection of fifty-four early drawings, mostly Italian scenes, in the
British Museum. Cozens lost them in Germany on his way from Rome to Britain, and they were only recovered by his son in
Florence in 1776. They show him as a highly skilled draughtsman in the style of the time, with a feeling for elegant composition. Some are wholly in pen and ink in the manner of line engravings. Others show extensive landscapes, elaborately drawn in pencil, and partly finished in ink. Others are washed in monochrome, and some in colour of a timid kind. In most there is little sky, but in one he has attempted a bold effect of sunlight streaming through cloud, and brightly illuminating several distinct spots in the landscape. There are several broad pencil drawings on greenish paper heightened with white. Altogether these show that by this time Cozens was a well-trained artist who observed nature and was not without poetical feeling. After his arrival in Britain he appears, from some drawings in the
Victoria and Albert Museum, to have adopted a much broader style, aiming at an imposing distribution of masses and large effects of light and shade. In 1785 Cozens published a
pamphlet on this manner of drawing landscapes from blots, called
A New Method of Assisting the Invention in Drawing Original Compositions of Landscape. Cozens defined a blot as "a production of chance with a small degree of design" and acknowledged the influence on his ideas of a passage in
Leonardo da Vinci's
Treatise on Painting, which recommends that artists should look for inspiration in stains or marks on old walls.
Joseph Wright of Derby was influenced by Cozens, owned paintings by him, and used his ideas as inspiration for his compositions. He also described the technique Cozens recommended for creation from blots. In 1778 Cozens published
Principles of Beauty relative to the Human Head (a work "of more ingenuity than value"), with nineteen engravings by
Francesco Bartolozzi. The list of subscribers included
William Beckford (father of Cozens's pupil
William Thomas Beckford),
Burke,
Garrick,
Flaxman, Sir
Joshua Reynolds, and other men of culture. In 1782
Thomas Banks exhibited his ''Head of a Majestic Beauty, composed on Mr.Cozens's principles
. Cozens also published The Various Species of Composition in Nature
, and The Shape, Skeleton, and Foliage of Thirty-two Species of Trees'' (1771, reprinted 1786). ==References==
