The mirror two-faced image of the protagonist of the novel by D. S. Merezhkovsky «Resurrected Gods. Leonardo da Vinci»

The novel "The Devil's Elixirs" by E. T. A. Hoffmann is considered in this article as one of possible references of the myth about Leonardo in the work "Resurrection of Gods. Leonardo da Vinci" by Dmitry Merezhkovsky. This statement is based on comparative identification of community of plot, perspective and images. Opposition of Christianity and Paganisms (apostasy), Man and art (genuine art vs. fake one), society mechanisation problem, human consciousness bifurcation and search of spiritual synthesis are central in the novels by E. T. A. Hoffman and Dmitry Merezhkovsky. A number of E. T. A. Hoffman images (Leonardo da Vinci, the artist's apprentice, the White deviless, the dual portrait) are realised in the novel by Dmitry Merezhkovsky.

Leonardo da Vinci in the 16th century, used injection replica techniques to study internal surfaces of the cerebral ventricles. Developments in replicating media have made it possible for modern morphologists to examine injection replicas of lung and kidney with the scanning electron microscope (SEM). Deeply concave surfaces and interrelationships to tubular structures are difficult to examine with the SEM. Injection replicas convert concavities to convexities and tubes to rods, overcoming these difficulties.Batson's plastic was injected into the renal artery of a horse kidney. Latex was injected into the pulmonary artery and cementex in the trachea of a cat. Following polymerization the tissues were removed by digestion in concentrated HCl. Slices of dog kidney were aldehyde fixed by immersion. Rat lung was aldehyde fixed by perfusion via the trachea at 30 cm H2O. Pieces of tissue 10 x 10 x 2 mm were critical point dried using CO2. Selected areas of replicas and tissues were coated with silver and gold and examined with the SEM.
