“The employment of mathematical symbols is perfectly natural when the relations between magnitudes are under discussion; and even if they are not rigorously necessary, it would hardly be reasonable to reject them, because they are not equally familiar to all readers and because they have sometimes been wrongly used, if they are able to facilitate the exposition of problems, to render it more concise, to open the way to more extended developments, and to avoid the digressions of vague argumentation.”

“It's much more a matter of playing the characters as they were written by the authors, because of the liberties that have been taken with pretty much all of them. They've all been distorted in one way or another, because the authors have hardly stuck to the facts.”

Tim Curry (1946) English actor, voice artist, comedian and singer

“I can hardly describe the discord produced by the comparison of the retouched part of the painting and the part left untouched, the former having lost entirely the immediacy and brio of the brushwork and the latter the mastery of sensitive and discerning touches... For it is true that the more one retouches under the pretext of restoration, the more harm one does, and even the artists themselves, were they able to return, would not able to retouch their painting perfectly on account of the necessary change in the hue of pigments over time… No painting by Titian should be relined, nor any paintings by a number of other painters.... and, even when it is possible, the operation is more likely to result in deterioration than in improvement of the painting.”

Francisco De Goya (1746–1828) Spanish painter and printmaker (1746–1828)

from his Letters 263-264. circa 1801; in Goya, A life in Letters, edited and introduced by Sarah Simmons; translations by Philip Troutman, London, Pimlico, 2004
Early 1801 - Goya was then First Painter of the Court - the artist is sent to check the results of some restoration operated on works belonging to the Spanish crown. His 263-264 letters reveal the total opposition of Goya against any cleaning or restoration of older paintings
