The Eagle's Nest

The Eagle’s Nest is by John Ruskin: ten lectures on the relation of natural science to art, given before the University of Oxford in Lent term, 1872. The preface says the lectures have been written, not with less care, but with less pains, than any in former courses. The speaker says one comes to the School of Literature to learn the range and dignity of conceptions, to the School of Art to learn the range and dignity of deeds, and to the School of Science to learn the range and dignity of knowledges.

The text says the greater number of Gothic arches may be regarded as the intersections of two spherical vaults. The text says the beauty of Gothic arches, and of their foliation, always involves reference to the strength of their structure, but only to their structure as self-sustaining, not as sustaining superincumbent weight. A list of subject entries with page references includes, among others, the heraldic ordinaries, their symbolism, and use in teaching colour.
