The Van Gogh Museum announced on Tuesday that two previously unknown drawings are now confirmed to be part of Vincent van Gogh's oeuvre, following extensive research conducted by the Van Gogh Museum into the subject, style, technique, materials and provenance.

Van Gogh's The Hill of Montmartre with Stone Quarry, 1886

The newly discovered drawing, The Hill of Montmartre with Stone Quarry, is a monochrome artwork created by the Dutch master from March 1886. It has been kept in the privately owned Van Vlissingen Art collection for more than 100 years until it was brought to the Van Gogh Museum in 2013 for authentication.

The sketch originally belonged to Johanna Van Gogh-Bonger, the wife of Vincent’s brother Theo. The work was consigned to art dealer J. H. de Bois in Haarlem in 1911, who sold the work in circa 1917. It has disappeared from view since then and never before been exhibited or included in a publication.

This discovery also led to the authentication of a second work in the possession. Another work, entitled The Hill at Montmartre (1886) and housed at the Van Gogh Museum, was previously rejected partly due to a lack of material for comparison. It shares an unmistakable connection to the newly-discovered drawing in terms of subject, size, style, technique and materials.

"The two drawings are clearly from the same hand and stylistically, are reminiscent of Van Gogh’s model drawings from early 1886, which he initially created in Antwerp and subsequently in Paris, in Cormon’s studio," Teio Meedendorp, the Senior Researcher at the Van Gogh Museum, said in a statement.

The last discovery of Van Gogh new drawing was made in 2012, the early pencil drawing Roman Youth (after Bargue after Bonnat) from 1880, a copy after an example used in Charles Bargue’s drawing course.

These two rare drawings are currently on display (until 6 May) in an exhibition titled Impressionism & Beyond. A Wonderful Journey at Singer Laren Museum in the Netherlands, together with works by major artists such as Monet, Manet, Renoir, Degas and Gauguin.

Meanwhile, two previously forgotten works by Rembrandt’s student Govert Flinck (1615-1660), were also revealed to the public at the Amsterdam Museum for the first time on Tuesday since disappearing around 1895.

Last described in an 1895 auction catalogue, these two works are believed to be portraits of Zeeland province representative Johan de Mauregenault and his wife Petronella van Panhuysm.
