Little is known about the precise origins of the Chamber of Reflection. There is some consensus that it first appeared in France around 1750, and the Hermetic nature of its symbolism indicates the direct or indirect influence of the Rosicrucians. Author and occultist Robert Ambelain goes as far as suggesting that the Rosicrucians deliberately infiltrated Masonic lodges in order to spread their ideas. Rosicrucian degrees appeared in some French rites during the second half of the eighteenth century (see main article Rosicrucianism). The form of the chamber has hardly changed since then, with minor variations across jurisdictions.
