Panel of Mona Lisa

Panel of Mona LIsa Left

The panel of Mona Lisa was protected by the old edge paper applied after 1939, but now that part has been removed and the part which was hidden can be observed directly.

The panel has taken on a brownish color, with traces of saws cut at the top and bottom edges.
There are also many traces of parasitic worm holes on the periphery and back of the panel.

This trimming clearly only involved the bare wood and not the paint layer, because there is a crest, or beard of the ground preparation running all round the perimeter of the picture itself.

The current width varies between 53.3 cm at the top of the panel and 53.4 at the bottom, and the height of the panel comprising the mona lisa is 79.2 cm on the right , 79.1 cm on the left , and 79.4 cm in the middle.

The unpainted border around panel are served to slot the panel into its original frame.

The Mona Lisa's panel was taken from a flat grain section from a trunk sawn lengthwise of poplar.
Poplar is common in Italy and is frequently used in Italian paintings. The weave of the wood can be seen from the rather faint rings running vertically, these are clearly visible on the left half of the panel back.

The panel cut out 500 years ago are not uniform size like modern times. The thickness of the panel shows between 12.4 mm and 13.8 mm in a recent survey.

Across the width, the median axis is thicker than the side borders in the bottom two thirds of the plank, a relationship reversed in the upper third, especially toward the top edge, where the central part is thinner than the side borders.

The details around of the panel are also interesting.
Unlike the sophisticated surface of Mona Lisa, the ground is rough and raised, and in part there are parts where the underlying panel is seen through.

The roughness of the surface is too contrasting.

In this way,Mona Lisa was always decorated on the picture frame even during the production.

 


 

 

 

Back of Panel

The panel always tends to warp backward.

Therefore, countermeasures are taken to prevent warp of the panel from progressing due to support by oak material and air conditioning management.

Regarding cracks, a clear rift which is clearly visible from the front also runs vertically on the head of Mona Lisa.
For that part, parts of the butterfly type wood are fitted in two places from the back, so that the split will not go any further.

The image below is the state without the oak material attached for panel reinforcement. The back side of the panel has been slightly reduced in thickness the past.
