About A Treatise on the Astrolabe
A Treatise on the Astrolabe is a medieval instruction manual on the astrolabe, completed by Geoffrey Chaucer in 1391. Notable as technical prose from a writer better known for poetry, it describes both the form and the proper use of the instrument. It was written in Middle English rather than the more typical Latin.
