The purpose of this “Post” is to provide the link (below) to my introduction to “Chapter 14 : Linear Perspective“, the second chapter of “Drawing with Knowledge” (the second BOOK in the two book volume). The main subject dealt with is uses and abuses of Linear Perspective. The chapter explains the purpose for which the rules the rule of linear perspective were developed and how over the years artists and teachers came to use them for other purposes for which they are not suited. It also explains how the rules of linear perspective can be used in new ways. A preliminary idea of what this means can be found in first paragraph of the “Introductory” to this chapter, which I have included below. Also see below for links to all published chapters from “Drawing with Feeling“, the first BOOK in the two book volume.
“Introductory” – from Chapter 14 : Linear perspective
Academic tradition divides the subject of “perspective” into two aspects, known as “aerial” and “linear”. Aerial perspective concerns colour changes due to the influence on appearances of atmospheric particles situated between the eye and an object being viewed at a distance, and is dealt with in a separate volume. In this book attention will be confined to linear perspective. Moreover, to avoid misunderstandings, it is important to stress that no attempt will be made to compete with the many existing texts on this subject which demonstrate that, when properly applied, the well-known laws can enable the construction of moderately realistic images without the need to actually look at anything. As far as I know there is nothing of interest to add to these, although, a great deal needs modifying in many of the texts on the subject which regrettably give us oversimplified and therefore misleading versions of this complex and elegant subject. Rather, in this volume, the laws of linear perspective are treated in a completely novel way: not as a set of instructions for the placement of lines on but as a tool for guiding looking strategies. This transformation is achieved by placing them in the context of ideas coming both from 19th century research into visual phenomena and from much more recent discoveries relating to the functioning of eyes and brains. In PART 2, the subject of anatomy will be treated in an analogous way for analogous reasons.

A list of chapters from “Drawing with Feeling“, book 1 of “Drawing on Both Sides of the Brain“
The purpose of this ‘Post’ is to provide the link (see below) to my introduction to “Drawing with Knowledge”, the second BOOK in the two book volume (See below for links with the published chapters of “Drawing with Feeling“, the first BOOK in the two book volume). The two main subjects dealt with are Linear Perspective and Anatomy.
This Post introduces Chapter 22 from my book “Painting with Light and colour”. It uses one of my paintings to discuss many issues that relate to viewing conditions. These all apply to all paintings, but it is difficult to find information about them in other books. Indeed, it was not until I began work on paintings including numbers of thin lines that I became fully aware of many of them. My awakening was a result of the coming together of many strands of the story I have been telling in my series of four books.
The dogmas of Marian Bohusz-Szyszko (see Chapter 1),
In general, whenever images of paintings are transferred to the computer screen, many of their qualities are lost. Sometimes this can be an advantage, but never for paintings that follow the dogmas of Professor Bohusz-Szyszko. This is particularly true for the images using thin lines discussed in this chapter and the next. Often, you will just have to take it on trust that the effects discussed are as described.

* If you ask Google “What is a Modernist painter”, you get the following excellet summary: “Modern art includes artistic work produced during the period extending roughly from the 1860s to the 1970s, and denotes the styles and philosophies of the art produced during that era. The term is usually associated with art in which the traditions of the past have been thrown aside in a spirit of experimentation.” However, if you had asked Manet, Cézanne, Van Gogh, Matisse, etc., etc., whether traditions of the past had been thrown aside, you would find that it was by no means all of them.
** Google says that the “integrity of the picture plane” is a phrase coined by the influential art critic Clement Greenberg in his essay “Modernist Painting”. It concerns the issue as to whether the fact of creating an“illusory pictorial space” interferes with perceptions of the “objectness”of the actual picture surface. This was a question of primary importance to the “Early Modernists” from the late 1860s onwards. For them, as explained in Chapter 6 of my book “Fresh Perspectives on Creativity”, the fact of the possibility of being aware of the actual surface of paintings was one of the reasons for what they believed to be their inherent superiority relative to photographs. Their belief was that, since“deception is immoral”, painters must avoid it at all costs. Despite the difficult-to-comprehend this questionable argument, it stuck for about a century. Thus, in the 1960s, it was still a potent aspect of the teaching of my two mentors, Professor Bohusz Szyszko and Michael Kidner. The difference between the “Early Modernists” and Clement Greenberg was that the former (and Professor Bohusz-Szyszko) thought it possible to depict illusory pictorial space without destroying the integrity of the picture surface. In contrast, Clement Greenberg asserted the impossiblilit of any such thing, as didPiet Mondrian and a number of earlier painters, plus a whole list of later artists, including Michael Kidner and Ellsworth Kelly.
As those who have read “Painting with Light”, the first Book in this Two Book Volume will realise, the early Modernists and Professor Bohusz-Szyszko got it wrong. The use of unmixed repeated colours do not disrupt the picture-surface, but rather the illusory pictorial space. They do so because our eye/brains read them as being on the picture surface and, consequently, as jumping out of any illusory pictorial space, which is allways behind it. It is thus, the integrity of illusory pictorial space that is disrupted.
Earlier chapters from “Painting with Light and Colour”:
This Post provides a link to chapter 18 of my book, “Painting with Light and Colour”. It is the last of the chapters in the part of the book dedicated to “painting with light”. Its title, “All you need to know about painting-2” is almost the same as the title of Chapter 1, except for the number 2 tagged on at the end. The grandiose claim was made by my teacher Professor Marian Bohuz-Szyszko, during a brief encounter on the very first day we met. He asserted that “all you need to know” can be summerised in two simple rules.
The purpose of the chapter is to consider the plausibility of his assertion in the light of the ideas developed in the Chapters 2 to 17. These not only delve into the historical origins of the rules, but also provide scientific evidence of their power as tools for artists.
After the link to Chapter 18, I have added a slightly edited version of its “Introductory”, as a means of better preparing you for its contents.
Introductory to chapter 18 of “Painting with Light and Colour”
We have now come to the last chapter and the question as to how to make the best use of the information and ideas presented.
The first chapter introduces the five propositions of Marian Bohusz-Szyszko, the ones that according to him constitute, “all you need to know about painting”. The chapters that follow provide an account of their historical and scientific origins and explain why they are so powerful. At the same time they point out some limitations. However, although the avoidance of repetition and the use of complex, complementary-containing colours can transform what artists can achieve, they certainly do not represent “all there is to know about painting”, not even with the modifications and extensions suggested in this book. Most notably, the Professor’s rules give short shrift to two subjects that many artists consider to be of the utmost importance Thus they:
Have no relevance to the kind of “colour dynamics” that can be generated between juxtaposed colours (the subject of the following chapters)
Do not address what is perhaps the most important topic of all, namely the role of the feelings.
Although a full discussion of the importance of the feelings as a driving force in all domains of creativity is reserved for “Fresh Perspectives on Creativity”, it would not do at all to neglect them entirely in what follows.
The earlier chapters from “Painting with Light and Colour
Elizabeth Cavé and her great friend Eugene Delacroix
In an earlier Post I told of the teaching of Horace Lecoq Boisbaudranand its widespread influence. In it I did not mention another important figure who also developed a method for training the memory. Her name was Elizabeth Cavé. Like Lecoq Boisbaudran her method eventually found favour with the establishment and was to some extent introduced into the national curriculum. She was also, over some 30 years, a personal friend and confidant, often described as “mistress”, of Eugène Delacroix, who was something of a Father figure to the young Impressionists, including:
Edgar Degas who, as a young man, went, with his friend Gustave Moreau (teacher of Matisse), to visit Delacroix in his studio. When they arrived, despite having been warned to expect a testy old cumudgeon, they were given a warm and generous welcome. In contrast they described his intellect “icy”, maybe a reaction to the scientific bent that led him to be an early champion of the ideas of Michel-Eugène Chevreul, the chemist who first enunciated the law of ‘simultaneous colour contrast’
Probably all the other young ‘Impressionists’ for whom it is said that a ‘must see’ experience was the application of Chevreul’s law to be found in the frescoes painted by Delacroix towards his life (between 1857 and 1861), in the L’Eglise St. Sulpice, Paris.
My letter to LRB
With all this information in my head, you can imagine how my interest perked up when I came across a quotation from Delacroix in an article by T.J.Clark, published in the London Review of Books in October 2019. In this Delacroix tells us that he experienced a paradigm shift in his approach to painting, from being “hounded by a love of exactitude” to employing his memory to sift out “what is striking and poetic”. He also states that this transformation occurred as a spin-off from his “African voyage” in 1832.
On reading this endorsement of the virtues of channelling experience through memory, I was immediately reminded of the philosophy of Lecoq Boisbaudran. From there my mind jumped to Elizabeth Cavé and to wondering whether Delacroix’s change of direction had any link to her teaching method. When I discovered that their liaison had started in earnest in 1832, I could not resist the thought that either she had influenced Delacroix or, perhaps more likely, vice versa. If so, there seemed to be quite a lot to add to what T.J.Clark had to say. Below is what I wrote.
T.J.Clark (LRB 10-10-2019) quotes Eugene Delacroix as dating a change from being hounded by a love of exactitude to making work based on “recalling” what is striking and poetic. He asserted that it came after his “African voyage”, which mean after his return from Morocco in 1832. When I read this I immediately realised that this date roughly coincided with the beginning of his relationship with Elizabeth Cavé in 1833. Whether or not her ideas were influenced by Delacroix or visa versa , she published ‘Le dessin sans maître’, which received a laudatory review from her, by now long standing, friend (in the ‘Revue de deux Mondes’ of September 1850). In it, she explained her method of teaching drawing which, according to her, she had been practising since 1847. Key to this was training of the memory. Two years earlier, in 1848, Horace Lecoq Boisbaudran published a compilation of two texts, ‘L’Éducation de la mémoire pittoresque’ and ‘la formation de l’artiste’, in which he explained his method, also based on training the memory. His connection with Delacroix can be inferred from the personages in the 1864 painting ‘Homage à Delacroix’ by his pupil Henri Fantin-Latour, in which we see others two students of Lecoq Boisbaudran, Alphonse Legros and Felix Bracquemond. Also in the painting is James MacNeil Whistler who is know to have learnt Lecoq Boisbaudran’s method from Alphonse Legros and who famously demonstrated it to a doubter. He did this, first, by looking at an unfamiliar landscape and, then, turning his back on it and painting it from memory (for more about the influence of Lecoq Boisbaudran and its plausible ramifications see http://www.painting-school.com/horace-lecoq-boisbaudran-influence
So how does all this relate to the quotation from Delacroix? The clue lies in his youthful “love of exactitude” being replaced by a more mature approach based on “recalling what was striking and poetic.” What Lecoq Boisbaudran would surely have argued is that the great man’s earlier obsession with ‘accuracy’ prepared him for his later personalised use of memory with all its benefits, for this was exactly what his teaching method (and presumably that of Elizabeth Cave) aimed at achieving. The main differences, he could argue, lay in the shortness of the time in which his students were expected to make their transition and the methodical progression from simple to complicated that characterised the learning exercises that made it possible. Surely, both Delacroix and Lecoq Boisbaudran would have concurred with Edgar Degas, significantly a great friend of Alphonse Legros, when he said, “It is always very well to copy what you see, but much better to draw what only the memory sees. Then you get a transformation, in which imagination works hand in hand with the memory and you reproduce only what has particularly struck you.”
As well as the personalisation of artistic output, the method had huge advantages in terms of rapidity of information pick up. The famous late watercolours (‘Cambodian dancers’, etc) of Rodin, another student and a lifelong admirer of Lecoq Boisbaudran and his teaching, illustrate both these advantages. Likewise the post-African paintings and drawings of Delacroix. Also, I find it hard to believe that there is not some connection here with Delacroix’s famous assertion that “any artists worth his salt should be able to draw a man that has been thrown out of a sixth floor window before he hits the ground.”
PS. For your interest, I was teaching on much the same principles as Lecoq Boisbaudran for at leat 25 years before I learnt of his existence. These I derived from research done at the University of Stirling in the early 1980s <http://www.painting-school.com/the-course/the-course-director/>.
