Mathematical Treasures - Adam Riese's Rechenbuch

This is a page from the 1550 Rechenbuch (reckoning book) of Adam Riese (1492–1559), one of the greatest reckoning masters of the 16th century.  The complete title of the book is Rechnung nach der lenge/auff den Linien und Feder.  This page (78) deals with the gauging of barrels, that is, with measuring the contents of a barrel.

This page from the Rechenbuch (6) has a table showing numbers in German words, in Roman numerals, and in the Hindu-Arabic numerals.

The images above have been obtained through the kind cooperation of the Rare Book and Manuscript Library of the Columbia University Libraries. The images below show a copy previously owned by Robert B. Honeyman (1897–1987) and Erwin Tomash (1921–2012) that was offered for sale by the German rare bookseller Milestones of Science Books.
