Renaissance drawing related to the Sistine Chapel ceiling newly attributed to Michelangelo Buonarroti.

A previously unknown sixteenth century black chalk drawing on paper relating to a decorative element of the Sisitine Chapel, is now attributed to Michelangelo Buonarroti by a Courtauld Institute PhD Scholar with a specialist focus in Michelangelo and his followers.

His assiduous fifty page report concludes that it is autograph based on stylistic grounds, and by similar method, eliminates possibilites of it being by another hand.

It has been confirmed by an eminent paper Historian, that the drawing paper bears the watermark seen in other Michelangelo drawings of the period.

A conservation scientist with decades of experience in this field believes it is by Michelangelo.

Recent provenance is unremarkable. However, looking back in time, there may be a provenance with the collector Pierre Crozat, 1665–1740. A single number is written in an old hand in ox-gall ink on the period mount, that corresponds to the lot number of a group of Michelangelo drawings in the important Mariette Paris auction sale catalogue of 1741. There were 1083 lots consisting of 19,201 of Crozat's drawings. The chances of the same number being inscribed on the mount are over a thousand to one.

The drawing has been the subject of study by the Chief Scientific Officer at the Fitzwilliam Museum in Cambridge. They have used advanced xray spectrometry techniques producing spectral data that identifies the exact mineral make-up of black chalks and white washes, thus providing a "fingerprint" of the media, to be able to match it with data from other Michelangelo drawings from the same period, that may exist in private or National collections.
