Franco-Flemish double-manual harpsichord,
Topics for Discussion regarding the restoration of the decorative paintwork
Section 1 - Introduction
This document is intended as an introduction to some of the many aspects of the restoration of the paintings and decorations on the instrument. It is reasonably thorough, but is not meant to be exhaustive. It is hoped that the analyses and examinations that are planned will help us to understand the decorative history of this harpsichord and to clarify the periods in which various aspects of the decoration took place. It is hoped, also, that the study of the paintwork will help us to understand the musical alterations to the instrument and to its decorations throughout its history. In the end, of course, the aim of the analyses and the restoration of the instrument is that the instrument will return, not to its state in 1750 or in 1786, but to a state that gives some idea of its splendour and magnificence that it displayed in the historical period.
The immediate motivation for writing ‘Topics’ is that Cinzia Pasquali and Alice Aurand are due next week (April 24-25, 2018) to make the initial assessment of the instrument’s decoration and will perhaps take some samples of the paintwork in order to try to make some clearer decisions about what treatments are necessary and to try to clarify some of the uncertainties about the instruments decorative history: http://www.arcanes.eu/fr/accueil/
The painting of the decorations on the instrument has suffered very badly in the past. This is partly the result of straightforward physical damage, of heavy-handed painting restorers but perhaps mostly as the result of a thick heavy layer of linseed-oil varnish that had badly discoloured and that had cross-linked and attached itself to the underlying paint layers. The removal of this varnish caused a considerable damage and a major loss of paint. During the removal of the varnish layer there were also found to be large patches of red/pink gesso whose presence was much disguised by the layer of dark varnish and indeed to having been painted over to fill in missing lacunae (see the photograph below). The gesso could only be removed mechanically, but this removal seemed to cause less damage than dissolving the layer of varnish. However, in many cases the removal of the bole seemed to cause more damage than it actually did because much of the later retouching was painted on top of the bole and was lost along with it. But there was clearly no paint there before the bole was applied.
The initial photo above gives a fairly good impression of the harpsichord before the thick layer of linseed oil varnish was removed. Much of the painting and decoration underneath this varnish was almost invisible, and could barely be discerned. The varnish was very thick in places and had cross-linked to the underlying paint. In places this had caused serious ‘un-natural’ cracklure, in other places it had simply been subject to creep and had pulled the underlying paint with it as it contracted. The damage caused by the varnish layer across the whole of the exterior of the instrument is the main source of concern and will be the main source of the difficulties encountered in the painting/decoration restoration.
The whole of those surfaces that were varnished with the linseed-oil varnish have been cleaned by local painting restorers whose expertise is in fine art painting restoration. The cleaning process removed a great deal of the original painted surface but this loss was, I think inevitable. Also as mentioned above there seemed to be more loss than actually occurred because the bole had, in many places been painted over. The inside of the lid and the case exterior (cheek, bentside, tail and spine) have ostensibly been restored and re-varnished, but the extensive work that I have now done on Christophe Huet and François Boucher has revealed that there are many problems with the previous restoration work and re-touching work done by the local restorers. This will be discussed in detail below.
This shows a good example of the patches of red bole which was unseen and virtually undetectable underneath the layer of linseed-oil varnish. Unlike the varnish the red bole was, fortunately, only poorly attached to the surface and could be removed effectively without much damage to the underlying painted decorations. The paint loss caused by the removal of the linseed oil varnish is clearly evident in this photograph, as it was over the whole of the exterior decorated and painted surfaces with the exception of the keywell above the keys which had not been varnished.
I have many, many pictures of the painted decorations of all parts of the decorations that I hope will be found to be useful in reconstructing those parts of the decoration that have been lost in the cleaning process.
Section 2 - The lid exterior
This shows the exterior of the lid as it is now - partially cleaned, but un-retouched and un-varnished.
Unfortunately the local restores did not leave a sample area untouched in order to leave a sample of the varnished and uncleaned surface. Hopefully an area under one or more of the hinges can be found still with the varnish in place. Under no circumstances should any varnish found underneath the hinges be removed so that at least some small sample of the linseed-oil varnish remains.
I firmly believe that the figures of Cupid, Flora and Juno on the left of the photograph above are by François Boucher. But the painting of the figure on the right seems to me reacts in the same way as tall of the other figures to UV, and so must have been painted by the same person at the same time. However, UV analysis shows that the face of this figure has been retouched in historical times, possibly in 1752/3. This figure seems to be that of Marie-Louise O’Murphy, mistress of King Louis XV from about 1753, , and so establishing the author of this part of the painting and its date are crucial to the correct reconstruction of the history of the instrument and its possible commissioning by the French Court.
Section 3 - The lid interior
The inside of the lid has, ostensibly, been cleaned, retouched and re-varnished.
Section 4 - The Lockboard, cheek, bentside and tail
The figures painted around the surfaces of the outside of the instrument that are normally visible, namely: the lockboard, the cheek, the bentside and the tail are decorated the with a series of paintings, possibly by Boucher, that represent a kind of procession of figures or amorini in a ‘Triumph of Love’ sequence. In art, Cupid often appears in multiples as the amorini, in the later terminology of art history, the equivalent of the Greek erotes (Aphrodite’s retinue). Cupids and amorini are a frequent motif of both Roman art and later Western Art of the classical tradition as they are here. The first of these multiple figures on the lockboard closing the keywell might be seen as the first in the series of ‘The Triumph of Love’, starting with the cupids or amores forging their arrows. As we move around to the cheek, the Amores are sharpening their arrows on a stone. The detailing of the stone, the pedal used to operate it, the water being spilled onto the stone from a scallop shell are all superbly observed and painted - although heavily and awkwardly overpainted.
Careful observation of the figures in the ‘Triumph of Love’ has shown both that these figures were initially painted by a painter of superlative skill and that they have subsequently been very badly overpainted by some very heavy-handed ‘restorers’. This overpainting has made an assessment of these paintings very difficult, and made the attribution of the original painter of these figures quite impossible.
Part 1 - The lockboard - outside
This photograph shows the outside of the lockboard at the moment the varnish removal was begun. It shows the dark varnish that has so badly damaged the paint and gilding. It also shows the way the lockboard was extended at both ends in 1786 to keep the figures and the lock itself centred on the board.
Here one of amorini figures is heating the arrowheads in a forge at the left. The central amorino wields a blacksmith’s hammer and is beating an arrowhead while the third amorino on the right holds the arrowhead firmly in position on the anvil.
This shows the drastic (and disastrous) losses to the outside of the lockboard.
These three photographs show the central lozenge of the painting on the outside of the lockboard (top left) uncleaned, top right with the varnish removed, but with the red bole which had clearly been painted over to create the top left version and, bottom, the lozenge without the red bole and with the disastrous losses.
Part 2 - The lockboard - inside
The inside, protected, surface of the front lockboard. It has been partially cleaned here, but shows clear evidence of one of the patches of red bole (top left) and of the thick heavy layer of linseed oil varnish.
The inner surface of the front lockboard after cleaning. This shows the differing amounts of new wood added (because of the scarf joint used) and the resulting difference in the reflectivity of the newer gilding.
The lockboard has not, at this stage been re-touched and varnished - this work is still all to be done. There is clearly much loss of paint. The decoration is centred but not symmetrical in the sense that it is not at all balanced in the way one would normally expect roccoco decoration to be. However, the loss and damage on this side of the lockboard is not nearly as extensive as it is on the other, front, side.
The design at the centre of the inside of the lockboard. The paintwork is generally in good condition with only minor losses, although still with considerable work to be done.
Part 3 - The figures in the sequence of ‘The Triumph of Love’:
Amour 1 - The amorini sharpen their arrows
Amour 2 - The archer getting a bit of practice.
Amour 3 - The badly restored ‘onlookers’.
Amour 4 - Two amorini showing how to do it.
Amour 5 - The strong guys!
Amour 6 - The victim is crowned and returns in glory.
A detail of the archer. Although less re-touched
than many of the others,
the head seems reasonably intact.
The head of the charioteer - this is in fairly good
condition , but still missing many highlights.
The head of the figure in the Amour 2 scene above.
The figure on the right is perhaps the least ‘restored’ and re-touched and shows the hand of the brilliant painter who was initially responsible for the whole of this part of the decoration. The hair and wings still reveal a large amount of detail and highlights. I feel that this figure gives some idea of the skill and brilliance of the 1750 painter. On the other hand, the left hand of this putto can only be described as distorted and gross as the result of the crude, unskilled overpainting and touching up. Although even in the head of the putto, the re-touching and over-painting is all too apparent, many important details remain: the highlights and detailing of the hair (except in the hair just above his forehead) and wings, and the painting of the ear with the highlight just at the top. But what is particularly noteworthy is the painting of the light reflected back off the body of the archer putto onto the face of this little brunette. This shows the skill of the painter in its highest and most sophisticated form. Although highlighted with light, the face is painted with a dark outline to distinguish it from the flesh tones of the body of the archer putto just behind him. In my view only a painter at the height of his/her powers could have painted this.
I feel that what is needed now is to remove the overpainting and re-touching from the faces and bodies of the other putti in the ‘Triumph of Love’ sequence to see if there is further evidence of this skill and technique lying hidden under the rest of the later over- painting and retouching.
Part 4 - Cupid - the last in the ‘Triumph of Love’ sequence - the figure painted on the tail of the case:
Here the left picture is a photograph of the tail after the varnish and bole were removed, but before any re-touching by the local restorer. The picture in the middle is the present state of the tail after retouching, ‘restoration’ and re-varnishing, and that on the right is a photograph taken with UV (650nm) showing the numerous re-touchings of the present state.
In classical mythology Cupid is the god of desire, erotic love, attraction and affection. He is often portrayed as Eros, the son of the love goddess Venus and the war god Mars. Although Eros is generally portrayed as a slender winged youth in Classical Greek art during the Hellenistic period, he was increasingly portrayed as a chubby boy. During this time, his iconography acquired the bow and arrow that represent his source of power: a person, or even a deity, who is shot by Cupid's arrow is filled with uncontrollable desire.
In both ancient and later art, Cupid is often shown riding a dolphin. Here he is not riding a dolphin, but it seems highly likely that the figure behind him is meant to be a dolphin and not some kind of an ill-defined monster that has been run through by a baseball bat! The (badly restored) torch in his right hand represents the fire of burning passion. He is also often shown wearing a helmet and carrying a buckler (a small round shield held by hand or worn on the forearm), perhaps in reference to Virgil's Omnia vincit amor or as political satire on wars for love or love as war. The buckler is absent here, but a golden helmet lies at Cupid’s feet.
In art Cupid often appears, as here, in multiples as the Amores, or amorini. The cupid appearing on the tail of the harpsichord is the final figure, and the last in the series of ‘The Triumph of Love’, starting with the cupids or amorini forging the arrows on the front flap closing the keywell.
Section 5 - The spine side
These photographs both show the condition of the spine side of the instrument. Importantly it should be noted that the spine side of a French harpsichord of the eighteenth century is usually left unpainted and un-decorated. After a great deal of searching I have concluded that this is the only eighteenth-century French harpsichord with a painted decoration on the spine (information kindly supplied by Alain Anselm). The fact that this instrument DOES have a painted spine suggests: a) that it was intended to be displayed as the splendid centre-piece of a room and b) that the additional extravagance of this decoration is one of the many features of the instrument that suggests that it was once the property of Louis XV and that its decoration was commissioned for him by Mme de Pompadour.
The many quirky features of the spine decoration are all similar to those of the normal style of Christophe Huet seen elsewhere in the Château de Chantilly, the Château des Champs sur Marne, and the Archives Nationales in the centre of Paris, and on the decoration of the 1733 Blanchet double-manual harpsichord in the Château de Thoiry just to the west of Paris and Versailles. There can be no doubt that Christophe Huet is the author of the spine decoration and no doubt that the spine decoration is an original feature of this harpsichord.
This decoration is generally in good condition, but still needs some work in the light of our knowledge of Huet’s normal style. The fact that this decoration is unique in the history of historical harpsichord building means that the correct restoration of the spine is a matter to be approached with the utmost caution and attention.
Section 6 - Additional images:
This picture shows a number of important features:
Section 7 - The gilding of the visible edges of the baseboard.
During the musical part of the restoration of this harpsichord it was found necessary to remove the South-American plywood baseboard (presumably dating from the ‘restoration’ of the instrument in 1971 by Roberto de Regina in Buenos Aires). Because the baseboard had been renewed and replaced a number of times in the course of the history of the instrument, the lower edges of the case sides have suffered damage in the past. When the new baseboard was given to the instrument in the present restoration by me, these damages were not treated by the gilding restorer but were simply gilded over. They now need to be filled in with gesso, gilded over and the reconstructed paintings around the sides of the case need to extend into the baseboard in a way that is ‘natural’ and in keeping with the rest of the decorations.
We have been very pleased by the work of the gilding restorer who has done all of the work on the gilding of the instrument and the stand. We want her now to do a bit more work on the stand, particularly to the feet, but otherwise she has left the stand with a satisfactory patina of age without making it look brand new. Should she be asked to continue this work, or will it be done by Cinzia and Alice?
Although the restoration of the paintwork and decoration is still unfinished, even at this stage this photographs gives a good idea of the splendour and richness of the decoration of ‘Big Goldie’!
