Dante and the early astronomers
A study of the astronomy behind Dante's poetry, written by Mary Acworth Orr and published by Gall and Inglis in London and Edinburgh in 1914 for general readers of literature and science history. Its line diagrams plot epicycles, deferents, and planetary paths as bare circles, arrows, and labelled dots on tinted paper, offering designers clean geometric schematics and old cosmological charts.
