Aratra Pentelici, Seven Lectures on the Elements of Sculpture / Given before the University of Oxford in Michaelmas Term, 1870

A series of lectures outlines the principles and practice of sculpture, insisting that its primary aim is the organized production of harmonious, rounded surfaces and well-ordered relief rather than mere imitation or structural ornament. The author treats the division of the arts, the problem of idolatry, and the role of imagination and likeness while analyzing form, light, and proportion through classical and medieval examples. Technical discussion addresses relief techniques, incision, and the relation between sculpture and architecture. Final lectures compare stylistic schools and major Renaissance figures to illustrate differing artistic aims and criteria for judgment.
