Detachment of wall paintings

The detachment of wall paintings involves the removal of a wall painting from the structure of which it formed part. Once a common practice, with the move towards preservation in situ, detachment is now largely restricted to cases where the only alternative is total loss.[3] According to the International Council on Monuments and Sites (ICOMOS), "detachment and transfer are dangerous, drastic and irreversible operations that severely affect the physical composition, material structure and aesthetic characteristics of wall paintings. These operations are, therefore, only justifiable in extreme cases when all options of in situ treatment are not viable."[4]

Christ Pantocrator from the Church of Agios Euphemianos, Lysi, Northern Cyprus (C13); detached and formerly exhibited at the Byzantine Fresco Chapel, Houston, Texas;[1] repatriated to the Republic of Cyprus in March 2012 and now displayed in the Byzantine Museum in Nicosia[2]

Origins

Vitruvius records how in Sparta, in 59 BC, "paintings have been taken out of certain walls by cutting through the bricks, enclosed in wooden frames, and brought to the Comitium".[5] A century later, apprised of paintings of Atalanta and Helen without drapery and "enflamed with lust", Caligula attempted to carry them off, but was prevented by the makeup of the plaster.[6] Maiuri cites examples of wall paintings in wooden frames excavated at Pompeii, a precursor to what was to follow in the 18th and 19th centuries.[7][8] The practice of detachment, in abeyance or undocumented for a millennium, was revived in Renaissance Italy, with several instances recorded by Vasari.[9]

Motivation

In their study, Mora, Mora, and Philippot cite four reasons for the "over-use" of detachment: the 19th-century division of the arts that privileged a "painting" divorced from its architectural and historical context; insensitivity to the aesthetic consequences, often partially concealed by restorers; the curiosity of art historians looking for sinopie; or perceived savings relating to the initial cost of treatment.[10] Commercial gain and exploitation as consumer goods by collectors, dealers and restorers provides another possible incentive.[11] This process enables nowadays' companies to offer their customers an authentic fresco, created in their laboratory according to the ancient technique and transferred onto a canvas to be shipped to the place of installation.[12]

Changing values
Main article: Values (heritage)

As the values of a society change, so to does its attitude towards works of the past.

Techniques
Mural by Banksy on the West Bank barrier (2005);[13] a wall painting's meaning is intimately related to its immediate physical setting[14][15]

There are three main methods, typically referred to by their Italian terms, namely stacco a massello, involving detachment and removal of painting, render, and some or all of the mural support; stacco or detachment of the painting with render alone; and strappo, lit. "tearing", lifting of only the paint layer, attached to a facing with adhesive.[16] In each case the resulting material must be applied to a new support.[17]

Criticisms

Minimum intervention and reversibility are core conservation ethics that favour preservation in situ.[18][19] Detachment breaks the intrinsic link between wall paintings and architecture; causes irreversible physical damage to the texture, topography, and tone of the painting; leaves a void in the stripped interior; with the introduction of new materials, typically leads to a cycle of retreatment; and has resulted in "many transfers in terrible condition that serve as examples of serious, albeit unintentional, maltreatment".[20]
