Wax models had been used for several centuries in Europe to depict anatomy of the human body; it appeared to have reached the peak of perfection in the 18 th century especially in Italy. Rich collections of such models in cities like Bologna and Florence illustrate the high standards that were attained by collaboration between artistic modelers and leading anatomists of those days. [1] This early wax modeling was known as ' Anatomica Plastica', where minute details of the human anatomy were depicted by wax models. The next logical step was illustration of diseases by use of wax models (Patho-anatomica plastica) and wax models (moulages) were used in various medical specialities like surgery, obstetrics, ophthalmology etc but it was in dermatology that these reached heights of artistic endeavor by faithfully reproducing the minutiae of skin diseases in a realistic three dimensional presentation that far surpassed any other teaching aids then available, like paintings, illustrations and photographs (Daguerreotypes) which were all two dimensional modalities. It is not surprising, therefore, that moulages soon formed the main teaching aids in dermatology and venereology till the 1940s, when the disruptions of World War II interrupted moulage production and good quality color photography became available and replaced moulages as the main teaching and recording medium for skin diseases.The making of moulages (derived from the French, mouler, meaning to mould) in general includes preparation of a negative image of the patients own skin and then filling this image with molten wax to depict the exact appearance of the skin and the disease that it bears.The negative mould was usually made from the patient's skin using plaster of Paris which was then filled up with molten beeswax and other organic and inorganic ingredients which were kept secret by the moulager. The ready wax cast was then painted on with appropriate colors to approximate the color of the skin and the lesions of the disease. To impart authenticity, were often added real hair and glass eyes whenever necessary. The whole model was mounted on a wooden board and sometimes enclosed by a glass cylinder.Because the skin is so readily accessible, this procedure could be repeated several times to capture various stages of the disease in the course of its evolution or devolution without much discomfort to the patients.While the practice of anatomic wax model making was widespread all over Europe, moulages of skin diseases were restricted to few places and the techniques were zealously guarded by the moulagers who often refused to take assistants or share their knowledge of moulage making.
