First edition of the fundamental book on the modern theory of numbers. With this book, the author, the 24-year old son of a bricklayer, began a new epoch in mathematics. It contains proof of the law of quadratic reciprocity, which had eluded both Euler and Legendre, and a new method of dividing the circle, the first discovery of this kind in Euclidean geometry since Antiquity. The book is extremely difficult to understand, which caused the compositors to make numerous typographical errors in the equations. Gauss insisted therefore on a lengthy errata as well as the cancellation of five leaves, all of which were duly carried out in this copy.
