Guidoccio di Giovanni Cozzarelli

Guidoccio Cozzarelli, also recorded as Guidoccio di Giovanni Cozzarelli or Guidoccio di Giovanni di Marco Cozzarelli, was born in Siena in 1450, the son of Giovanni di Marco di Nanni di Cozzarello, a woodworker. He trained in the workshop of the Sienese painter Matteo di Giovanni, with documented association running from about 1470 to 1483, and his mature style remained close enough to his master's that individual paintings have at times been attributed to one artist or the other.

Cozzarelli's documented activity centers on Siena. He is recorded working for the Santa Maria della Scala hospital around 1470, and around 1480 to 1482 he contributed illuminations to Siena Cathedral's antiphonals. He is also credited with altarpieces for San Bernardino in Sinalunga, generally placed around 1483 and 1486, and with a polyptych, now fragmentary, in Rosia. Later in his career his style shifted under the influence of the painter Pietro Orioli, to the point that works by the two have at times been confused.

Sources place his death in Siena in 1516 or 1517. The Kress Foundation, the Web Gallery of Art, and the Metropolitan Museum give 1516 or 1516/17, while German and Portuguese Wikipedia entries give 1517. The exact year is not fully settled in the available scholarship.

Modern references discuss Cozzarelli chiefly in terms of technique and attribution rather than critical interpretation. Multiple sources note that his paintings have at times been confused with those of his teacher, Matteo di Giovanni, and later with those of Pietro Orioli, because of how closely his mature style tracked theirs. The Metropolitan Museum's scholarly catalogue text notes that Cozzarelli was traditionally dismissed as an uninspired imitator of Matteo di Giovanni, a view it argues is undercut by his altarpieces at San Bernardino in Sinalunga and the polyptych in Rosia. No verbatim quotations from named critics in major outlets could be verified for this profile, so none are reproduced here.

Cozzarelli's market is thin and largely historical rather than active. His best-documented result is USD 242,500, including premium, for The Madonna and Child with Saints Julian the Hospitaler, Roch and Sebastian, Below the Dead Christ Set in a Landscape, Flanked by Saints Cosmas, Damian and Two Other Male Saints, sold at Sotheby's New York on 31 January 2013, a figure market databases cite as his auction record. A smaller, more recent sale, a Visitazione at Pandolfini in Florence, realized EUR 26,460 including fees, reported in November 2023. Public data does not support a ranked list of his second and third highest results, so the 2013 sale should be treated as the best-documented ceiling rather than as evidence of a broad price history. The bulk of his known output resides in museum and church collections rather than in private hands, which further limits the frequency and comparability of public sales.

Cozzarelli is a documented, museum-collected Sienese painter and illuminator with no catalogue raisonne and no gallery or estate representation; his works reach the market only occasionally, through the Old Master auction and dealer trade. The scarcity of confirmed realized prices, combined with a documented history of misattribution with Matteo di Giovanni, means that provenance research and direct scholarly attribution matter more here than for artists with an established price history. Collectors should treat the 2013 result as the best-documented ceiling for his market and the far smaller 2023 sale as a reminder of how thin and variable outcomes can be, rather than as proof of a stable trend.
