“ They are, for instance, the visible forms, colours, and shades of the parts, understood according to the maxims of perspective; (for of perspective every one has a practical knowledge, as every one has of grammar;) the effort by which we fix both our eyes on the same object, and adjust each eye to distinct vision ”

Portrait of Vernon Lee Vernon Lee,  The Beautiful: An Introduction to Psychological Aesthetics

“ In other words and as I shall never tire of repeating, the differentiating characteristic of art is that it makes you think back to the shape once that shape has conveyed its message or done its business of calling your attention or exciting your emotions. And the first and foremost problem, for instance of painting, is that of preventing the beholder's eye from being carried, by lines of perspective, outside the frame and even persistently out of the centre of the picture ”

N. Hawkins,  Self-Help Mechanical Drawing: An Educational Treatise (1902)

“ The word perspective means to see through; the word perspective being derived from the Latin word perspicere, to look through, hence, perspective is a science which teaches us to see correctly and enables us to represent the appearance of anything we may wish to draw; care should be taken in perspective drawing, to select objects interesting in themselves, and the best specimens of their class, so as to cultivate taste, while they at the same time afford useful and instructive drawing lessons. ”
