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 comparitive 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 connection with the sale of the Crozat collection by Mariette in Paris in 1741. 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 catalogue of 1083 lots consisting of 19,201 drawings. The chances of the same number being inscribed on the mount are over a thousand to one.

IT has been subject to scientific study by the Chief Scientific Officer at the Fitzwilliam Museum in Cambridge. Spectral data has been produced for the black chalk and white washes, revealing a quantitative elemental fingerprint, to be able to match it and with data from other Michelangelo drawings that may exist in collections, from the same period.
