The exaggerated eyes of fourth-century Roman emperors like Constantine the Great (illustration) reflect this character.[3] The concept found expression in poetry into the 17th century, most famously in John Donne's poem "The Extasie":
Our eye-beams twisted, and did thred Our eyes, upon one double string; So to'entergraft our hands, as yet Was all the meanes to make us one, And pictures in our eyes to get Was all our propagation.
In the same period John Milton wrote, of having gone blind, "When I consider how my light is spent", meaning that he had lost the capacity to generate eye beams.
Later in the century, Newtonian optics and increased understanding of the structure of the eye rendered the old concept invalid, but it was revived as an aspect of monstrous superhuman capabilities in popular culture of the 20th century.
In Algernon Swinburne's "Atalanta in Calydon" the conception is revived for poetic purposes, enriching the poem's pagan context in the Huntsman's invocation of Artemis:
Hear now and help, and lift no violent hand, But favourable and fair as thine eye's beam, Hidden and shown in heaven".
In T.S. Eliot's rose garden episode that introduces "Burnt Norton" eyebeams persist in the fusion of possible pasts and presents like unheard music:
The unheard music hidden in the shrubbery And the unseen eyebeam crossed, for the roses Had the look of flowers that are looked at.
The New Zealand poet Edward Tregear instanced "the lurid eye-beam of the angry Bull"— Taurus of the zodiac— among the familiar stars above the alien wilderness of New Zealand.[5]
In computer graphics, the concept of eye beams is fruitfully resurrected in ray tracing (in which the bouncing of eye beams around a scene is simulated computationally).

Aristotle was an Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science.
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared and the ultraviolet.
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.
The problem of universals is an ancient question from metaphysics that has inspired a range of philosophical topics and disputes: "Should the properties an object has in common with other objects, such as color and shape, be considered to exist beyond those objects? And if a property exists separately from objects, what is the nature of that existence?"
Robert Grosseteste, also known as Robert Greathead or Robert of Lincoln, was an English statesman, scholastic philosopher, theologian, scientist and Bishop of Lincoln. He was born of humble parents in Suffolk, but the associations with the village of Stradbroke is a post-medieval tradition. Upon his death, he was revered as a saint in England, but attempts to procure a formal canonisation failed. A. C. Crombie called him "the real founder of the tradition of scientific thought in medieval Oxford, and in some ways, of the modern English intellectual tradition". As a theologian, however, he contributed to increasing hostility to Jews and Judaism, and spread the accusation that Jews had purposefully suppressed prophetic knowledge of the coming of Christ, through his translation of the Testaments of the Twelve Patriarchs.
"Form of the Good", or more literally "the idea of the good", is a concept in the philosophy of Plato. The definition of the Good is a perfect, eternal, and changeless Form, existing outside space and time. It is a Platonic ideal.
Essence has various meanings and uses for different thinkers and in different contexts. It is used in philosophy and theology as a designation for the property or set of properties or attributes that make an entity the entity it is or, expressed negatively, without which it would lose its identity. Essence is contrasted with accident, which is a property or attribute the entity has accidentally or contingently, but upon which its identity does not depend.
Eros is a concept in ancient Greek philosophy referring to sensual or passionate love, from which the term erotic is derived. Eros has also been used in philosophy and psychology in a much wider sense, almost as an equivalent to "life energy". The Protestant philosopher C. S. Lewis posits it as one of the four ancient Greek words for love in Christianity, alongside storge, philia, and agape.
A collimator is a device which narrows a beam of particles or waves. To narrow can mean either to cause the directions of motion to become more aligned in a specific direction, or to cause the spatial cross section of the beam to become smaller.
Emission theory or extramission theory or extromissionism is the proposal that visual perception is accomplished by eye beams emitted by the eyes. This theory has been replaced by intromission theory, which is that visual perception comes from something representative of the object entering the eyes. Modern physics has confirmed that light is physically transmitted by photons from a light source, such as the sun, to visible objects, and finishing with the detector, such as a human eye or camera.
Platonism is the philosophy of Plato and philosophical systems closely derived from it, though contemporary Platonists do not necessarily accept all doctrines of Plato. Platonism had a profound effect on Western thought. In its most basic fundamentals, Platonism affirms the existence of abstract objects, which are asserted to exist in a third realm distinct from both the sensible external world and from the internal world of consciousness, and is the opposite of nominalism. This can apply to properties, types, propositions, meanings, numbers, sets, truth values, and so on. Philosophers who affirm the existence of abstract objects are sometimes called Platonists; those who deny their existence are sometimes called nominalists. The terms "Platonism" and "nominalism" also have established senses in the history of philosophy. They denote positions that have little to do with the modern notion of an abstract object.
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'. Optics was significantly reformed by the developments in the medieval Islamic world, such as the beginnings of physical and physiological optics, and then significantly advanced in early modern Europe, where diffractive optics began. These earlier studies on optics are now known as "classical optics". The term "modern optics" refers to areas of optical research that largely developed in the 20th century, such as wave optics and quantum optics.
The Book of Optics is a seven-volume treatise on optics and other fields of study composed by the medieval Arab scholar Ibn al-Haytham, known in the West as Alhazen or Alhacen.
The natural sciences saw various advancements during the Golden Age of Islam, adding a number of innovations to the Transmission of the Classics. During this period, Islamic theology was encouraging of thinkers to find knowledge. Thinkers from this period included Al-Farabi, Abu Bishr Matta, Ibn Sina, al-Hassan Ibn al-Haytham and Ibn Bajjah. These works and the important commentaries on them were the wellspring of science during the medieval period. They were translated into Arabic, the lingua franca of this period.
Common sense is sound, practical judgement concerning everyday matters, or a basic ability to perceive, understand, and judge in a manner that is shared by nearly all people.
In the time of William Shakespeare, there were commonly reckoned to be five wits and five senses. The five wits were sometimes taken to be synonymous with the five senses, but were otherwise also known and regarded as the five inward wits, distinguishing them from the five senses, which were the five outward wits.
Optics is a work on the geometry of vision written by the Greek mathematician Euclid around 300 BC. The earliest surviving manuscript of Optics is in Greek and dates from the 10th century AD.
The theory of Forms, theory of Ideas, Platonic idealism, or Platonic realism is a philosophical theory of metaphysics developed by the Classical Greek philosopher Plato. The theory suggests that the physical world is not as real or true as "Forms". According to this theory, Forms—conventionally capitalized and also commonly translated as "Ideas"—are the non-physical, timeless, absolute, and unchangeable essences of all things, of which objects and matter in the physical world are merely imitations. Plato speaks of these entities only through the characters of his dialogues who sometimes suggest that these Forms are the only objects of study that can provide knowledge. The theory itself is contested from within Plato's dialogues, and it is a general point of controversy in philosophy. Nonetheless, the theory is considered to be a classical solution to the problem of universals.
Mardonius, also spelled Mardonios, was a Roman rhetorician, philosopher and educator of Gothic descent. Mardonius was the childhood tutor and adviser of the 4th century Roman emperor Julian, on whom he had an immense influence.
Medieval aesthetics refers to the general philosophy of beauty during the Medieval period. Although Aesthetics did not exist as a field of study during the Middle Ages, influential thinkers active during the period did discuss the nature of beauty and thus an understanding of medieval aesthetics can be obtained from their writings.
