In the Light of Leonardo da Vinci orn in 1452, Leonardo lived in Milan from 1482 to 1499 and from 1506 to 1513. He died in France five hundred years ago leaving the world his paintings, his drawings, his scientific and technical notes.In his manuscripts, the notes regarding light are amazing. For Leonardo, light behaves like the wind on a wheat field, it bends the ears of wheat without changing their position. He was the first to sense the undulatory nature of light. And, observing the waves, this was how Leonardo explained the beauty of the sea in the sunlight: “The innumerable semblances that form the innumerable waves of the sea reflect the sun’s rays that cross these waves, are responsible for the continual and widespread splendour of the surface of the sea” (Codex Arundel, f. 94 v). Does light travel fast? For Leonardo, “the sun, as soon as it appears in the East, immediately moves with its rays to the West”, and the course of the rays is shorter in nature, as he “always appreciated the taste of simplicity and the ease of Nature that does not do what cannot be done, it does not utilize many things when it can do so with few, and skilfully carries out what we find difficult to figure out.” Why is the sky light blue? Leonardo knows why. The light blue colour comes from the atmosphere, it depends, now we know, on the scattering of light on particles in the atmosphere; Leonardo reasons as if he already knew Lord Rayleigh’s theory on the scattering of light, which was first described three hundred years later. “I say that the blueness we see in the atmosphere is not intrinsic colour, but is caused by warm vapour evaporated in minute and insensible atoms on which the solar rays fall, rendering them luminous against the infinite darkness of the fiery sphere which lies beyond and includes it” (Leicester Codex, also known as the Hammer Codex). LUCE pays homage to Leonardo da Vinci on the occasion of the celebrations for the 500th anniversary of his death. A short and precious story of light as the protagonist of the studies and observations underlying the creations of the famous Florentine master. The author, Empio Malara, curated the exhibition and the book entitled Leonardo e le vie d’acqua (Leonardo and the waterways, 1984) and the volume Leonardo, Vanvitelli e Bellotto a Vaprio d’Adda (Leonardo, Vanvitelli and Bellotto in Vaprio d’Adda, 2005) 14 LUCE 328 / EPIFANIE DI LUCE Leonardo is aware of the nobility of vision, due to the faculty of the intellect: “The eye, through which the beauty of the universe is reflected by those who contemplate it, is so excellent that whosoever may lose it cannot see the representation of all the works of nature… leaving the soul in a dark prison, where all hope of seeing the sun, the light of the whole world, is lost.” In order to study light, he used a glass prism, realizing that white is not a colour, but “has the power of receiving all the other colours.” Carlo Pedretti writes that Leonardo’s observations regarding the topic of light and optical physics and “his never ending calculations, have not been interpreted completely to date.” However, the greatest expert on Leonardo points out that “his marvellous drawings remain, characterized by impeccable graphic purity.” In fact, the drawings of the series from darkness to light, the figures dancing in the open throughout the passage from dark clouds to bright sunlight, are graphically significant as scientific observations. Augusto Marinoni rightly states that painting, in Leonardo, is science, as it is a mental state before being a practical process. A concept that was clearly expressed by Leonardo on painting, “which brings philosophy and subtle speculation to the consideration of the nature of all forms – seas and plains, trees, animals, plants and flowers – which are surrounded by shade and light.” “Take note as you portray things,” Leonardo suggested with reference to the chiaroscuro technique, “that among the shadows are shadows of imperceptible darkness and shape… What can be seen between light and shadow, will prove to be more relevant than what is in the light or in the shadows”. This is a brilliant concept that finds its application in Leonardo’s wonderful masterpieces, first of all the “transitory movement” (between a previous action and a subsequent action), which is perfectly described in a pictorial form, as Fabio Lopez noted, in the Last Supper of S. Maria delle Grazie in Milan. Among the infinite number of projects by Leonardo, there are also the “night lights”, lamps with more or less elaborate lenses, and also a very beautiful table lamp whose intensity can be adjusted, designed in Windsor sheet n. 12675v. Many lights are mentioned in the Atlantic Codex (f. 368v-a) and in Codex Arundel (f. 283v), which can all be dated between 1505 and 1507. These show the object with the same “perspective view” adopted for architectural drawings, never subordinating functionality to decoration, Carlo Pedretti states. Leonardo on light has still to be discovered, five hundred years after he was buried in Amboise on May 2 nd , 1519. 9 – To be continued. For “Epiphanies of light”, to date, the following short stories by Empio Malara have been published in LUCE: “Alessandro Manzoni, a creator of light” (n.317, September 2016); “Herman Melville. Light that invites us on a journey” (n.321, September 2017); “Light and dark in the portrait of James Joyce as a young man” (n.322, December 2017); “Flashes and lights in Hemingway’s A Farewell to Arms” (n.323, March 2018); “The artificial sun in the novel The magic mountain by Thomas Mann” (n.324, June 2018); “The irreverent and irrational light in some texts by Carlo Emilio Gadda” (n.325, September 2018). “Philip Roth’s revealing lights in American Pastoral” (n.326, December 2018); “Marcel Proust’s lighted windows in the novel Swann’s Way” (n.327, March 2019).
