#### The Euclid Collection

The National Library's collection of works ascribed to Euclid contains more than 300 volumes, representing 270 editions, and is considered to be an important reference point for Euclidean bibliographical studies.
The collection has been developed through additions to the initial thirty\-nine volumes of early editions of the *Elements* that [Sir Charles Thomas\-Stanford](/wiki/Sir_Charles_Thomas-Stanford "Sir Charles Thomas-Stanford") donated in 1927, including further eleven volumes from Sir Charles in 1928\. With the subsequent additions the collection covers all of Euclid's works, including *Data, Phaenomena, Optica* and *Catoptrica* along with numerous editions of the *Elements,* in many languages. There are two incunabula (Erhard Ratdolt, Venice, 1482 and Leonardus de Basilea \& Gulielmus de Papia, Vicenza, 1491\) in the collection, as well as seventy\-three volumes from the sixteenth century, including the first English (Reynold Wolfe, London, 1551\) and Arabic (Typographia Medicea, Rome, 1594\) editions.
