Marco d'Oggiono

Marco d'Oggiono was probably born around 1470, likely at Oggiono in Brianza near Milan, though a family of Italian sources places his birth in Milan itself, to a goldsmith father with roots in Oggiono. Reliable information about his early training is scarce. Art historians reconstruct an early apprenticeship with an unnamed Lombard master, possibly close to Bernardo Zenale or Bernardino Butinone, before he appears in the documentary record.

The first firm document on his career is a 1487 contract in Milan, in which, already an independent master with his own workshop, he took on Protasio Crivelli as an apprentice in miniature painting. A second document, dated shortly afterward, ties his name to Leonardo da Vinci's, and he is generally accepted as the "Marco" recorded in Leonardo's studio around 1490. In 1491, he received a joint commission for an altarpiece in the Griffi Chapel in Milan. Between about 1498 and 1504 he worked on altarpieces and frescoes in several towns before returning to Milan, where he painted an undated fresco cycle for the church of Santa Maria della Pace and became known for numerous painted copies of Leonardo's Last Supper.

His death is not precisely dated. A 2020 essay for the Auckland Art Gallery states that he died of the plague, probably in June 1524, in Milan, an account also followed by the National Gallery, the Royal Academy of Arts, and the Web Gallery of Art. Other standard references give different years: the Treccani Enciclopedia Italiana and the German Wikipedia place his death around 1530, while the English, Spanish, and Catalan Wikipedia entries argue that 1549 is the best accepted date among some later writers. No source supplies an exact day.

Early twentieth-century assessments were mixed. The Catholic Encyclopedia, in its 1913 entry, judged that he "cannot be regarded as an important artist, or even a very good copyist, but in his pictures the sky and mountains and the distant landscapes are always worthy of consideration, and in these we probably get the painter's best original work." Around the same period, the critic Paul George Konody drew a contrast in discussing the disputed Isleworth Mona Lisa, writing that its hands, "with their careful and somewhat hard drawing and terra cotta coloring, suggest at once the name of Leonardo's pupil, Marco d'Oggionno," while attributing the head and bust to Leonardo himself, a comment that captures how criticism of d'Oggiono has long proceeded by comparison with his teacher rather than on independent terms. Modern curatorial writing takes a warmer view, describing him as building a successful artistic career out of Leonardo's techniques and themes, appealing to a broad public that wanted fashionable Leonardesque work.

D'Oggiono's paintings appear at auction only occasionally, and public sale records are thin compared with the size of his surviving output. The highest publicly documented auction price is EUR 226,000, paid at Dorotheum in Vienna on 24 April 2024 for an Old Master painting attributed to him; the lot's full title is not specified in the available sale record. Dorotheum listed a further work by the artist in an April 2026 sale, estimated at EUR 80,000 to 120,000, and Sotheby's has separately offered a Virgin and Child with the Infant Saint John attributed to him with an estimate of GBP 800,000 to 1,200,000; neither result is confirmed as a completed sale in the available record, so neither is treated here as an auction high.

There is no catalogue raisonne and no estate to authenticate works, so provenance and connoisseurship carry unusual weight. Attribution of individual paintings has shifted historically between d'Oggiono, Boltraffio, and the wider Leonardo circle, and buyers should expect that some works described under his name in older literature may since have been reassigned. The auction market is thin and infrequent, so the EUR 226,000 Dorotheum result should be read as a data point rather than a stable benchmark, and unsold or unconfirmed high estimates, such as the Sotheby's listing above GBP 800,000, should not be mistaken for realized prices. The deepest, most reliable evidence of his standing remains his presence in permanent collections such as the Louvre, the National Gallery in London, and the Metropolitan Museum of Art.
