The use of mirrors for measuring distance and height has its origins in ancient Greek science. In his Optics, Euclid demonstrated how the reflection of light could be geometrically employed to determine an object’s altitude or range with remarkable precision. During the Islamic Golden Age, scholars adopted and further developed his methods. For example, ʿAbd al-Raḥmān al-Khāzinī (active ca. 1115–1130 CE), in his treatise On Marvelous Instruments, not only explained Euclid’s single-mirror method but also introduced an innovative Double-Mirror Method. This innovation enabled the simultaneous determination of both height and distance of an object through one observation. Al-Khāzinī’s contribution represents a significant step in linking theoretical geometry with practical applications in surveying and engineering within the scientific tradition of the medieval Islamic world. This article examines his methods in detail.
