Characterisation of beeswax in works of art by gas chromatography-mass spectrometry and pyrolysis-gas chromatography-mass spectrometry procedures.

Pyrolysis (Py) with in situ derivatisation with hexamethyldisilazane-gas chroma-break tography-mass spectrometry (GC-MS) and a gas chromatography-mass spectrometry procedure based on microwave-assisted saponification were used to identify the organic components in small sized beeswax samples. With the latter procedure quantitative recoveries can be made and hydrocarbons, alcohols and omega-1-diols in the neutral fraction, and fatty acids and omega-1-hydroxy acids in the acidic fraction can be efficiently separated and detected. Both procedures were used to characterise a wax anatomic sculpture "The Plague" (1691-1694) by Gaetano Zumbo, resulting in the identification of beeswax and a Pinaceae resin. The GC-MS analysis brought to light some essential differences in beeswax composition between the raw material and the old modelled wax thus giving some clear indications about the recipe used by the sculptor.

Trimethylsulfonium hydroxide as derivatization reagent for the chemical investigation of drying oils in works of art by gas chromatography.

A procedure for the determination of fatty acids (FA) and glycerol in oils has been developed. The method includes a derivatization step of the FAs into their methyl esters or a transesterification of the triacylglycerols with trimethylsulfonium hydroxide (TMSH), respectively. The analysis is carried out by gas chromatography with parallel flame ionization and mass spectrometric detection. The parameters involved in the transesterification reaction were optimized. Only the stoichiometric ratio of TMSH:total FA amount showed a significant influence on the reaction yield. Relative standard deviations for 10 replicates were below 3% for all FAs studied and their linearity range was 0.5-50 mmol/L, when using heptadecanoic acid as an internal standard. The final procedure was rapid and required little sample handling. It was then tested on fresh oil samples and presented satisfying results, in agreement with previous works.

[Tatoos, piercing: body art? Body damage? Debasement of the body or return to a primitive way of life?].

Tatoos and piercing, though they might appear as something like a trend, if not a craze, remain for a majority minority and even fringe practices. For the adolescent, questing for his identity (no more a child, not yet an adult), the tegmental sign is a way of engraving in the flesh dramatic events of his existence. The body mark is a search for independence, a symbolic attainment of self-reliance, a way of severing the umbilical cord and of asserting oneself. In face of a life no longer under control, the body is an object at hand, on which self-will is almost unbridled... These body modifications testify to change.

Thomas Eakins' Agnew Clinic. a study of medicine through art.

In 1889, Thomas Eakins was commissioned to paint a portrait of Dr. David Hayes Agnew to commemorate his exemplary career as a physician and teacher at The University of Pennsylvania. What was originally proposed as a three-quarters portrait of the retiring professor quickly became an enormous painting depicting an operating theater with Dr. Agnew assuming his role as both surgeon and educator. When comparing this piece with an earlier Eakins' painting, The Gross Clinic, one can trace the rapid evolution of surgical techniques that accompanied medicine's advancement in the late 19th century. Eakins obviously embraced this progress, but was the public ready to do so too?
