The images are original steampunk ofgraveconcern creations based upon the historical fields of electrical physiology, and chemistry. Electrical physiology (the use of electricity by biological organisms) was first proposed by the Italian physician and anatomist Luigi Galvani (1737 –1798). In 1780, he discovered that the muscles of dead frog’s legs twitched when struck by an electrical spark. Galvani’s work influenced Mary Shelley in writing Frankenstein in 1816. The period from the late 17th to the early 19th century also witnessed revolutionary discoveries in the field of chemistry by Robert Boyle (1627–1691), Antoine Lavoisier (1743 –1794), Joseph Priestley (1733 – 1804) and John Dalton, (1766 –1844). Alchemy, chemistry and medicine all fitted within the same frame in the 17th century; the development of early  laboratory techniques, theory, terminology, and experimental methods by alchemists, eventually led to the founding of modern chemistry in the 18th and 19th centuries.
