'''Giovanni Francesco Barbieri''' (February 8, 1591 – December 22, 1666),<ref name="TreccaniBiografico1964">Miller, 1964</ref> better known as ('''il''') '''Guercino'''<ref>{{cite web|url=http://besidetheeasel.blogspot.se/2013/02/guercino-il-magnifico.html|title=Beside the easel |publisher=besidetheeasel.blogspot.se|access-date=14 September 2017}}</ref> ({{IPA|it|ɡwerˈtʃiːno|-|It-Guercino.wav}}), was an [[Italian Baroque painter]] and draftsman from [[Cento]] in the [[Emilia-Romagna|Emilia]] region, who was active in [[Rome]] and [[Bologna]]. The vigorous naturalism of his early manner contrasts with the classical equilibrium of his later works. His many drawings are noted for their luminosity and lively style.

Giovanni Francesco Barbieri was born into a family of [[peasant farmer]]s in [[Cento]], a town in the [[Po Valley]] mid-way between [[Bologna]] and [[Ferrara]].<ref name="Mahon1937a">Mahon, 1937a</ref> Being [[Strabismus|cross-eyed]], at an early age he acquired the nickname by which he is universally known, Guercino (a [[diminutive]] of the Italian noun {{lang|it|[[wikt:guercio|guercio]]}},  meaning 'squinter').<ref name="Oxford">Turner, 2003</ref> Mainly self-taught, at the age of 16, he worked as apprentice in the shop of [[Benedetto Gennari]], a painter of the [[Bolognese School (painting)|Bolognese School]].<ref>Griswold 1991, p. 6</ref> An early commission was for the decoration with frescoes (1615–1616<ref>{{cite web |title=Casa Pannini di Cento |url=https://www.geoplan.it/luoghi-interesse-italia/monumenti-provincia-ferrara/cartina-monumenti-cento/monumenti-cento-casa-pannini.htm |website=www.geoplan.it |access-date=8 February 2019 |language=it}}</ref>) of Casa Pannini in Cento, where the [[Realism (arts)|naturalism]] of his [[Landscape painting#17th and 18th centuries|landscape]]s already reveals considerable artistic independence, as do his landscapes on canvas ''[[Moonlit Landscape]]'' and ''[[Country Concert]]'' from the same era.<ref>Stone, pp. 3, 37.</ref> In Bologna, he won the praise of [[Ludovico Carracci]]. He always acknowledged that his early style had been influenced by study of a Madonna painted by Ludovico Carracci for the Capuchin church in Cento, affectionately known as "La Carraccina".<ref>{{cite web |title=La Carraccina |url=http://bbcc.ibc.regione.emilia-romagna.it/pater/loadcard.do?id_card=164519 |website=bbcc.ibc.regione.emilia-romagna.it |publisher=Regione Emilia Romagna |access-date=9 February 2019 |language=it}}</ref>

His painting ''[[Et in Arcadia ego (Guercino)|Et in Arcadia ego]]'' from around 1618–1622 contains the first known usage anywhere of the Latin motto, [[Et in Arcadia ego (Poussin)|later taken up]] by [[Poussin]] and others, signifying that [[Memento mori|death lurks]] even in the most [[Arcadia (utopia)|idyllic setting]].<ref>{{cite news |last1=Lubbock |first1=Tom |title=Guercino: Et in Arcadia Ego (1618–22) |url=https://www.independent.co.uk/arts-entertainment/art/great-works/guercino-et-in-arcadia-ego-1618-22-744410.html |access-date=7 February 2019 |work=The Independent |date=23 February 2007 |language=en}}</ref>  The dramatic composition of this canvas (related to his ''Flaying of [[Marsyas]] by Apollo'' (1617–1618<ref>{{cite web |title=Palazzo Pitti: Galleria Palatina – Apollo e Marsia |url=http://www.abcfirenze.com/GalleriaFotografica.asp?tipo=U&RicM=309&Foto=GalleriaPalatina-D35.jpg |website=www.abcfirenze.com |language=it |access-date=2019-02-09 |archive-date=2023-03-29 |archive-url=https://web.archive.org/web/20230329110135/http://www.abcfirenze.com/GalleriaFotografica.asp?tipo=U&RicM=309&Foto=GalleriaPalatina-D35.jpg |url-status=dead }}</ref>) created for [[Cosimo II de' Medici, Grand Duke of Tuscany]], which shares the same pair of shepherds<ref>{{cite web |title=Et in Arcadia Ego by Guercino |url=https://www.wga.hu/html_m/g/guercino/0/arcadia.html |website=www.wga.hu |publisher=Web Gallery of Art |access-date=8 February 2019}}</ref>) is typical of Guercino's early works, which are often tumultuous in conception.<ref>Griswold 1991, p. 13</ref> He painted two large canvases, ''[[Samson]] Seized by Philistines'' (1619) and ''[[Elijah]] Fed by Ravens'' (1620), for Cardinal [[Giacomo Serra (cardinal)|Giacomo Serra]], a Papal Legate to [[Ferrara]].<ref>{{cite web |title=Samson Captured by the Philistines |url=https://www.metmuseum.org/art/collection/search/436603 |website=www.metmuseum.org |publisher=Metropolitan Museum of Art |access-date=8 February 2019}}</ref><ref name="Vivian1971">Vivian, 1971</ref> Painted at a time when it is unlikely that Guercino could have seen [[Caravaggio]]'s work in Rome, these works nevertheless display a starkly naturalistic Caravaggesque style.

[[File:Guercino Flagellazione.jpg|thumbnail| Guercino – ''[[Flagellation of Christ]]'' (1657)]]
Guercino was recommended by Marchese [[House of Bentivoglio|Enzo Bentivoglio]] to the newly elected Bolognese [[Ludovisi (family)|Ludovisi]] Pope, [[Pope Gregory XV]] in 1621.<ref>[[Lawrence Gowing]], ed., Biographical Encyclopedia of Artists, v.2 (Facts on File, 2005): 291.</ref> The years he spent in Rome, 1621–23, were very productive. From this period are his frescoes ''Aurora'' at the casino of the [[Casino di Villa Boncompagni Ludovisi|Villa Ludovisi]], the ceiling in [[San Crisogono]] (1622) of ''San Chrysogonus in Glory'', the portrait of Pope Gregory XV (now in the [[Getty Museum]]), and the ''[[St. Petronilla Altarpiece]]'' for [[St. Peter's Basilica]] in the Vatican (now in the [[Capitoline Museums]]).

==Return to Bologna==
Following the death of Gregory XV in 1623, Guercino returned to his hometown of Cento.  In 1626, he began his [[fresco]]es in [[Piacenza Cathedral]]. The details of his career after 1629 are well documented in the account book, the ''Libro dei Conti di Casa Barbieri'', that Guercino and his brother [[Paolo Antonio Barbieri]], a notable painter of [[Still life#Seventeenth century|still life]]s, kept updated, and which has been preserved.<ref>Griswold 1991, p. 35</ref> Between 1618 and 1631, [[Giovanni Battista Pasqualini]] produced 67 engravings that document the early production of Guercino, which is not included in the ''Libro dei Conti''.<ref name="Gozzi2006">{{cite web |last1=Gozzi |first1=Fausto |title=Sacro e Profano nelle Incisioni da Guercino |url=http://docplayer.it/19262888-Sacro-e-profano-nelle-incisioni-da-guercino-cento-1590-1666.html |publisher=Culturalia |access-date=12 February 2019 |language=it |date=2006}}</ref> In 1642, following the death of his commercial rival [[Guido Reni]], Guercino moved his busy workshop to Bologna, where he was now able to take over Reni's role as the city's leading painter of sacred subjects. In 1655, the [[Franciscan Order]] of Reggio{{Clarify|date=March 2025|reason=Presumably Reggio Emillia?}} paid him 300 [[ducat]]s for the altarpiece of ''Saint Luke Displaying a Painting of the Madonna and Child'' (now in [[Nelson-Atkins Museum of Art]], Kansas City).<ref name="smarth">{{cite web | title =Guercino's Saint Luke Displaying a Painting of the Virgin | publisher =[[Smarthistory]] at [[Khan Academy]] | url =http://smarthistory.khanacademy.org/guercino.html | access-date =March 15, 2013 | archive-date =November 2, 2014 | archive-url =https://web.archive.org/web/20141102030315/http://smarthistory.khanacademy.org/guercino.html | url-status =dead }}</ref> The [[Corsini family]] also paid him 300 ducats for the ''Flagellation of Christ'' painted in 1657.

==Style==
Guercino was remarkable for the extreme rapidity of his executions: he completed no fewer than 106 large altarpieces for churches, and his other paintings amount to about 144. He was also a prolific draftsman. His production includes many drawings, usually in ink, washed ink, or red chalk. Most of them were made as preparatory studies for his paintings, but he also drew landscapes, [[Genre works|genre subjects]], and caricatures for his own enjoyment. Guercino's drawings are known for their fluent style in which "rapid, calligraphic pen strokes combined with dots, dashes, and parallel hatching lines describe the forms".<ref>Griswold 1991, p. 36</ref>

Despite presumably having [[monocular vision]] due to a [[Amblyopia#Strabismus|'lazy']] right eye, Guercino showed remarkable facility to [[Depth perception|imply depth]] in his works, perhaps assisted by an enhanced [[Contrast (vision)|perception of light and shade]] thanks to compensation by the healthy eye.<ref name="Scholtz2019">Scholtz et al, 2019</ref> Other artists with different types of strabismus include [[Rembrandt]], [[Dürer]], [[Degas]], [[Picasso]] and (possibly) [[Leonardo da Vinci]].<ref>{{cite journal |last1=Tyler |first1=CW |title=Evidence That Leonardo da Vinci Had Strabismus. |journal=JAMA Ophthalmology |volume=137 |issue=1 |pages=82–86 |date=18 October 2018 |doi=10.1001/jamaophthalmol.2018.3833 |pmid=30347053 |url=https://christophertyler.org/CWTyler/Art%20Investigations/ART%20PDFs/Tyler_JAMA-0_180017.pdf |pmc=6439801}}</ref>

==Pupils==
Guercino continued to paint and teach until the end of his life, amassing a notable fortune. He died on December 22, 1666, in Bologna.<ref>{{Cite web |title=Guercino (Giovanni Francesco Barbieri) {{!}} The Vocation of Saint Aloysius (Luigi) Gonzaga |url=https://www.metmuseum.org/art/collection/search/436604 |access-date=2023-04-12 |website=The Metropolitan Museum of Art |language=en}}</ref> As he never married, his estate passed to his nephews and pupils, [[Benedetto Gennari II]] and [[Cesare Gennari]].<ref name="Oxford" /> Other pupils include [[Giulio Coralli]],<ref>Orlandi, 1719, p. 207</ref> [[Giuseppe Bonati]] of Ferrara,<ref>Orlandi, p. 207</ref> [[Cristoforo Serra]] of Cesena,<ref>Orlandi, p. 120.</ref> Father [[Cesare Pronti]] of Ferrara,<ref>Orlandi, p. 350.</ref> [[Sebastiano Ghezzi]],<ref>Orlandi, p. 399</ref> [[Sebastiano Bombelli]],<ref>Orlandi, p. 397.</ref> [[Lorenzo Bergonzoni]] of Bologna,<ref>Orlandi, p. 294.</ref> [[Francesco Paglia]] of Brescia.,<ref>Orlandi, p. 171</ref> [[Benedetto Zallone]] of Cento, [[Bartolomeo Caravoglia]],<ref>Lanzi, 1847, pp. 309–310</ref> [[Giuseppe Maria Galeppini]] of Forli, and [[Matteo Loves]].

== Exhibitions ==
