This article is devoted to two theorems on tangent circles, which were discovered by the Iranian geometer Abu Sah?l Kuhi (fourth century H.). The two theorems were inspired by the Book of Lemmas (makhudhat) attributed to Archimedes. Kuh?'s original treatise is lost, but the two theorems are found in Nas??r al-D? nTu?s?'s edition of the Lemmas of Archimedes. They then appeared in Latin translations in 1659 in London and again in 1661 in Florence, and in 1695 in a revised Dutch version in Amsterdam. The present article compares the original Arabic version of Kuh?'s theorems (in the presentation of T?us?) with the revised Dutch version.

The mathematical treatises known as Ta?r?r al-mutawassi??t, “Revision of the Middle books”, are a collection of Greek and Arabic treatises which were re-edited by Na??r al-D?n al-??s?. This paper explores the nature of the editorial work ??s? did, showing that it is not a simple rendering of the original text but that it involves major revisions and in fact original additions. For the first time, a collated version of ??s?’s revision on the treatise on the measurement of the circle (by Archimedes) is provided. A translation of the Arabic text is put side by side with a rendition of the treatise as it was circulated before ??s?’s time. An in-depth analysis of the text elucidates the nature of ??s?’s contributions to the text. This article also provides modest corrections to earlier studies by W. R. Knorr and P. Luckey.
