Since its invention, photography has had a dual nature as both art and science, which have never been mutually exclusive. This cyanotype was part of a series in which cadavers were frozen and then thinly sliced by an anonymous physician, either from side to side or from front to back. In a process not fully understood, the slice was probably put on glass and contact printed to a negative. Then the negatives of the frozen segments were eventually printed on large cyanotype sheets, providing a life-size, accurate record of the position of organs and bones in that particular section. This image is of a slice toward the back half of a male body.
