Guercino
[Barbieri, Giovanni Francesco]
(b Cento, ?2 Feb 1591; d Bologna, 22 Dec 1666).
Italian painter and draughtsman. He was one of the leading painters of
the Bolognese school and one of the most accomplished draughtsmen of the
Italian Baroque. His paintings show a command of subtle effects of light
and dark, with the figures revealing a wide variety of gesture and
facial expression, the result of the artist’s good grasp of human
psychology. Guercino’s style changed dramatically during his long
career. His early works are robust in handling, rich in muted colour and
dramatic in lighting and composition. But after a short visit to Rome in
1621–3, his painting began slowly to alter as he came under the
influence of a more classical style of painting, then so popular in
official circles. He was deeply affected by the austere classicism of
one of his greatest rivals, Guido Reni. Following Reni’s death in 1642,
Guercino moved from his native Cento, where he had previously spent
almost the whole of his career, to Bologna, and assumed the position of
the city’s principal painter. His activity as a painter is particularly
well documented, thanks to the extensive list of his commissions in
Malvasia’s biography (based on documentation to which he had access in
Guercino’s house), together with the Libro dei conti (account
book) recording payments for his commissions, which was kept in
Guercino’s studio from 1629 until his death by his younger brother,
PAOLO ANTONIO BARBIERI, with whom he occasionally collaborated.
