Euclid postulated that visual rays proceed from the eyes onto objects, and that the different visual properties of the objects were determined by how the visual rays struck them. Here the red square is an actual object, while the yellow plane shows how the object is perceived. 1573 edition in Italian
Alternatively, Euclid's can be interpreted as a mathematical model whose only constraint was to save the phenomena, without the need of a strict correspondence between each theoretical entity and a physical counterpart. Measuring the speed of light was one line of evidence that spelled the end of emission theory as anything other than a metaphor.
Catoptrics is the title of two texts from ancient Greece: . The Pseudo-Euclidean Catoptrics.This book is attributed to Euclid, [3] although the contents are a mixture of work dating from Euclid's time together with work which dates to the Roman period. [4]
Commentary on the Data of Euclid. This work is written at a relatively advanced level as Theon tends to shorten Euclid's proofs rather than amplify them. [2] Commentary on the Optics of Euclid. This elementary-level work is believed to consist of lecture notes compiled by a student of Theon. [2] Commentary on the Almagest.
Optics began with the development of lenses by the ancient Egyptians and Mesopotamians, followed by theories on light and vision developed by ancient Greek philosophers, and the development of geometrical optics in the Greco-Roman world. The word optics is derived from the Greek term τα ὀπτικά meaning 'appearance, look'. [1]
Euclid’s first images were released in November 2023, but the telescope began regularly observing the sky in February. So far, the observatory has completed 12% of its survey.

The Euclid telescope spied a globular cluster — a huge collection of hundreds of thousands of stars bound together by gravity — located approximately 7,800 light-years away from Earth.
