Review of British Writer in Middle Age

Chaucer's Treatise on the Astrolabe provides a detailed description of the form and use of the astrolabe, and it is often cited as one of the earliest examples of technical writing in the English language. This work demonstrates Chaucer's scientific knowledge in addition to his literary skills. Another scientific work, The Equatorie of the Planetis, is similar in nature to the Treatise on the Astrolabe and was once attributed to Chaucer based on its language and handwriting. However, modern scholars have since disputed this attribution.
