Rafael Mirami (Italian: Raffaele Mirami; fl. 1582) was a 16th-century Jewish author and optical physicist from the city of Ferrara.^[1] He is described as having "pioneered" the field of catoptrics.^[2]

Mirami was active in the 16th century in the city of Ferrara. He wrote poetry and studied the science of optics and mirrors.^[3] He described little of himself in his writing, but presented himself as Jewish and a physicist.^[4] His Treatise, A Concise Introduction to the First Part of the Specularia..., was published in 1582.^[5] Some have credited his work around mirrors to have been influential in the development of scientific skepticism using reflective thinking.^[6] He also cited the field of catoptrics development and discovery to the thinking of sages, requiring a superior state of mind and wisdom. This has been credited as a fallacy of appeal to ancient wisdom.^[7]

Mirami's work in catoptrics allowed him to make astronomical calculations based on reflections,^[8] and his research in its applications is credited with having helped Pope Gregory XIII recalculate measurements for the creation of the Gregorian calendar.^[2]

He was an admirer of Abramo Colorni, and often cited him in his works.^[9][10] He also cited in his treatise the works of Dante, Horace, and Petrarch.^[11]
