JACOBI, Carl Gustav Jakob. *Canon Arithmeticus sive Tabulae quibus exhibentur pro singulis numeris primis vel primorum potestatibus infra 1000 numeri ad dados indices et indices ad dados numeros pertinentes*. First edition of this seminal work in the history of 19th-century arithmetic and number theory. Berolini (Berlin), Typis Academicis, 1839. In-4, red half-percaline Bradel binding with very small corners, smooth spine. Later binding. XL and 249 pp. In Latin. Spine very slightly rubbed; two slight stains on the last two leaves. First edition. Published in Berlin in 1839 by the Royal Prussian Academy of Sciences, Carl Gustav Jacob Jacobi’s (1804–1851) *Canon Arithmeticus* is a classic of number theory from the pre-computer era. In it, the algebraist calculates for the very first time the indices and discrete logarithms associated with the primitive roots of the set of prime numbers and their powers less than 1,000. A beautiful copy in a modern binding of this classic of mathematical bibliophilia.
