Jean Corbechon, Livre des propriétés des choses

France, Paris
c. 1415
MS 251

De proprietatibus rerum (On the Properties of Things), written in Latin by Bartholomew the Englishman c. 1240, was translated into French in 1372 by Jean Corbechon, chaplain of Charles V of France (1338-1380). Corbechon produced the French version at the command of the king who was an avid bibliophile. Commissioned by Amadeus VIII, Count of Savoy (1383-1451) and grandnephew of Charles V, this spectacular copy of Corbechon’s text was illuminated by the Master of the Mazarine Hours in Paris c. 1415.

The manuscript was illuminated by the Master of the Mazarine Hours and a number of assistants who painted the backgrounds of the miniatures and the minor text decoration. The richly coloured backgrounds of five of the nineteen miniatures were painted over instructions to the assistants written in Middle Dutch or German (fols. 104r, 163r, 166v, 174r, and 247v, see ‘Artists’ Materials’). The instructions reveal that the Master of the Mazarine Hours and his assistants were Northerners who had established themselves in Paris, a cosmopolitan hub of the arts and centre of courtly culture. This discovery lends material support to the stylistic and documentary evidence about the international artistic community in Paris c. 1400, which was dominated by immigrants from the Low Countries.

This manuscript was made for Amadeus VIII, Count of Savoy (1383-1451). In the modern era, the volume belonged to Brigadier-General Archibald Stirling of Keir and Cawdor (1867-1931) who gave it to the Fitzwilliam Museum in 1897.

The first book of the encyclopaedia opens with a half-page miniature of the Garden of Eden framed by a three-sided bar border, enclosed within a full vine-leaf border with zoomorphic extensions and angels. Seventeen smaller miniatures, with borders in a similar style, introduce the other books. The second book has two supplementary images, but the miniatures for Books 6, 9 and 16 are missing because the opening pages of these chapters were removed. In keeping with the pedagogical nature of the text, several of the miniatures show masters lecturing on the principles of astronomy, medicine, natural history and other disciplines. Sometimes the lessons take place in a classroom, but often the master and scholars are depicted outdoors, as if observing at first hand the natural phenomena discussed.

The Mazarine Master used a wide range of materials – minerals and organics – in pure form as well as complex mixtures. His palette includes red lead, vermilion, lead-tin yellow type I, lead white, carbon-based black and ultramarine. Lead-tin yellow was mixed with an organic colourant in some green areas, but with a copper-based pigment (possibly verdigris) in others. A red dye was mixed with lead white to obtain pink hues, and with ultramarine blue in purple areas. Grey hues were achieved by mixing lead white and carbon black. Numerous shades of brown were obtained with ochre pigments, at times mixed with umbers, vermilion and possibly with other compounds, extending the palette further. The most complex mixtures are present in the flesh tones (see Artists’ Techniques).  

The burnished gold leaf in the borders was laid over a ground containing a red earth and a calcium compound, possibly chalk. The gilded halos in the miniatures, however, appear to have been laid directly over the parchment.

The design of each miniature was carefully planned by the Mazarine Master, who sketched his compositions in detail, as revealed by infrared images. Extensive underdrawing is visible in the draperies and in the landscapes, some of which were only loosely sketched and then modified at the painting stage (e.g. fols. 166v, 247v).

Infrared imaging has also revealed the presence of written instructions, currently hidden beneath the paint layers, in five of the nineteen miniatures painted by the Mazarine Master.

Attired in a red robe, the master addresses two scholars. Two tall stalks of white lilies, emblems of the patron, Amadeus VIII of Savoy, are depicted in the background. A third stalk of lilies was initially designed to appear to the left of the master, as revealed by the infrared image (see Infrared Layer). However, after his assistants had painted the sky and grass, the Mazarine Master decided to include the two scholars instead. Evidently, the Mazarine Master’s ideas evolved while he was working, and he strove to improve his original composition. Because the two scholars were not part of his original plan, they are not depicted in the underdrawing and no area of blank parchment was reserved for them. Instead, they had to be painted directly on top of the background. This is apparent in the infrared image in which the head of the scholar in the centre appears to float in mid-air. The Mazarine Master wrote the word ‘himel’ (‘sky’ in German) in the upper left of the miniature, to inform his assistants that they should paint an outdoors scene.
