Liber

The prosperous Hanseatic city of Hamburg with its thriving cultural life always attracted capable minds. One of these was Thomas Selle (1599-1663), who worked here as city cantor from 1641. Around 1650, he compiled what he considered to be the most relevant of his own sacred compositions for printing, in order to preserve his work for posterity. As was customary at the time, there were different instrumentation variants of the works, so that he presented several alternatives in Concertuum Latino Sacrorum. The result is a fascinating compendium by one of the most important composers of his time.

- Following on from the 2000 edition of Jan De Witt’s Elementa Curvarum Linearum, Liber Primus, this book provides the accompanying translation of the second volume of Elementa Curvarum Linearum (Foundations of Curved Lines). One of the first books to be published on Analytic Geometry, it was originally written in Latin by the Dutch statesman and mathematician Jan de Witt, soon after Descartes’ invention of the subject.

First published in 1202, Fibonacci's "Liber abaci" was one of the most important books on mathematics in the Middle Ages, introducing Arabic numerals and methods throughout Europe.
