This book contributes to a worldwide history of textual criticism and critical editions of ancient scientific texts. It first looks at ancient editorial practices, and at their impact on modern editions. Contributions analyze how, through time, the perception of what a text was may have changed, and influenced how scholarly texts were made accessible. The second section looks at the historical, political and social contexts within which editions and translations of ancient scientific texts were produced. Finally, the last two parts examine the specificities of editions and translations that bore on scholarly documents. Not only is there a focus on how the elements specific to scientific texts—such as diagrams and numbers—were treated, but case studies analyzing the specific work carried out to edit mathematical and astronomical texts of the past are also offered to the reader. The scholarship displayed in this work lays the foundation for further studies on the history of critical editions and raises questions to those who make scholarly translations and critical editions today.

In the 5th century the Indian mathematician Aryabhata (476-499) wrote a small but famous work on astronomy, the Aryabhatiya. This treatise, written in 118 verses, gives in its second chapter a summary of Hindu mathematics up to that time. Two hundred years later, an Indian astronomer called Bhaskara glossed this mathematial chapter of the Aryabhatiya.

An english translation of Bhaskara’s commentary and a mathematical supplement are presented in two volumes.

Subjects treated in Bhaskara’s commentary range from computing the volume of an equilateral tetrahedron to the interest on a loaned capital, from computations on series to an elaborate process to solve a Diophantine equation.

This volume contains an introduction and the literal translation.

The introduction aims at providing a general background for the translation and is divided in three sections: the first locates Bhaskara’s text, the second looks at its mathematical contents and the third section analyzes the relations of the commentary and the treatise.
