In 1864 a new series of papers on Art was begun, the only published work upon Art of all these ten years. The papers ran in _The Art Journal_ from January to July, 1865, and from January to April. 1866, under the title of "The Cestus of Aglaia," by which was meant the Girdle, or restraining law, of Beauty, as personified in the wife of Hephaestus, "the Lord of Labour." Their intention was to suggest, and to evoke by correspondence, "some laws for present practice of art in our schools, which may be admitted, if not with absolute, at least with a sufficient consent, by leading artists." As a first step the author asked for the elementary rules of drawing. For his own contribution he showed the value of the "pure line," such as he had used in his own early drawings. Later on, he had adopted a looser and more picturesque style of handling the point; and in the "Elements of Drawing" he had taught his readers to take Rembrandt's etchings as exemplary. But now he felt that this "evasive" manner, as he called it, had its dangers. And so these papers attempted to supersede the amateurish object lesson of the earlier work by stricter rules for a severer style; prematurely, as it proved, for the chapters came to an end before the promised code was formulated. The same work was taken up again in "The Laws of Fésole"; but the use of the pure line, which Ruskin's precepts failed to enforce, was, in the end, taught to the public by the charming practice of Mr. Walter Crane and Miss Greenaway. A lecture at the Camberwell Working Men's Institute on "Work and Play" was given on January 24th, 1865; which, as it was printed in "The Crown of Wild Olive," we will notice further on. Various letters and papers on political and social economy and other subjects hardly call for separate notice: with the exception of one very important address to the Royal Institution of British Architects, given May 15th, "On the Study of Architecture in our Schools." CHAPTER V "ETHICS OF THE DUST" (1865) Writing to his father from Manchester about the lecture of February 22, 1859--"The Unity of Art"--Ruskin mentions, among various people of interest whom he was meeting, such as Sir Elkanah Armitage and Mrs. Gaskell, how "Miss Bell and four young ladies came from Chester to hear me, and I promised to pay them a visit on my way home, to their apparent great contentment." The visit was paid on his way back from Yorkshire. He wrote: "WINNINGTON, NORTHWICH, CHESHIRE. "12 _March_, 1859.
