Title

Armenian Bole

Subject

Armenian bole, also known as bolus armeni, is a reddish clay containing iron oxide. It was used in antiquity as medicine, and later as a paint pigment, ground layer for gliding, polishing compound, and food color. Its elasticity and intense red color makes it sought after by painters and goldsmiths.

Description

At the end of the fourteenth century and start of the fifteenth century, Armenian bole as a recommended base for water gilding was mentioned for the first time by Johannes Archerius and Cennino Cennini. The red color of the gilding base in many fourteenth- and fifteenth-century Italian manuscripts is likely Armenian bole or a similar red earth. The usage of Armenian bole reached its peak between the end of the fourteenth century and the eighteenth century, both in the western tradition as well as the east.

As its name suggests, Armenian bole comes from Armenia and surrounding areas of the Mediterranean. It was imported into Europe particularly for its use in gilding but also for its medicinal use. Increased importation of Armenian bole in the fourteenth and fifteenth centuries has been attributed to a number of reasons. One is the spread of water gilding techniques and their practice throughout Europe. Another explanation is increased demand for its believed healing effects against the plague during the epidemics of the time.

As the mining of similar clays spread throughout regions of Europe in the sixteenth century, the import of Mediterranean boles gradually decreased in the seventeenth and eighteenth centuries. Emanuel Mendes da Costa mentioned that it was “dug in Armenia, but is seldom or never to be found genuine in our shops” in 1757. The term “bole” was confused or interchanged with terms like “red earth” or “red ochre,” and other red clays were sold as or substituted for Armenian bole. As such, the exact composition of Armenian bole used by painters was (and to some degree still is) unclear.

In Ms. Fr. 640:
Fol. 6r - “For laying down and seating burnished gold and giving red or green or blue”
…Next take fine boli armeni* & sanguine, as much of one as of the other, also lamb tallow the size of a bean or a pea depending on the quantity of bole, and a little willow charcoal, or as much as the tallow, & half a walnut shell full of half-burned saffron. Some put in a little candy sugar. Grind all together with water, & apply it without gum or glue, & let it dry, & rub the place that you want to gild with a piece of white cloth to better smooth it, & when the rubbed place is a little shiny, it is a sign that the gold will be carried well…
Fol. 7v - “Against gonorrhea”
Aquæ fabrorum antiquæ lb i., boli Armeniæ in tel tenuissimum pollinem redactæ ℥.i., mellis communis ʒ.iii. coquantur ad mellis despumationem. Tum refrigerata colentur cum forti expressione & de colatura utatur per injectionem.
[Translation: Old smiths' water, i lb, Armenian bole reduced to the finest powder, i ℥, common honey, iii ʒ, shall be boiled to clarify the honey. Once cooled, it shall be strained with great pressure & the filtrate shall be used by injection.]
Fol. 12v - “Molding stucco promptly”
Grind & pulverize finely brick or Armenian bole or sanguine & incorporate it with melted wax, & thus melted, cast like the others on a relief medal, & thus you will have a hollow form where you will be able to cast with plaster, pestled paper, or terre chimolée.
