During the late thirteenth and early fourteenth centuries a group of monks with occult interests donated what became a remarkable collection of more than thirty magic texts to the library of the ...Benedictine abbey of St. Augustine’s in Canterbury. The monks collected texts that provided positive justifications for the practice of magic and books in which works of magic were copied side by side with works of more licit genres. In Magic in the Cloister, Sophie Page uses this collection to explore the gradual shift toward more positive attitudes to magical texts and ideas in medieval Europe. She examines what attracted monks to magic texts, in spite of the dangers involved in studying condemned works, and how the monks combined magic with their intellectual interests and monastic life. By showing how it was possible for religious insiders to integrate magical studies with their orthodox worldview, Magic in the Cloister contributes to a broader understanding of the role of magical texts and ideas and their acceptance in the late Middle Ages.
Continuing the series of philological and historical commentaries on Ammianus' Res Gestae this volume deals with Book 27, in which the author deals with military operations and internal affairs. In ...the central part of the book the emperor Valentinian is portrayed.

The determination of the composition of illuminated manuscripts’ components is an important tool for the better understanding of their history, their origin and the procedures carried out for their elaboration, providing an insight into techniques and materials used in the times of their fabrication. By focusing on all three important aspects of an illuminated manuscript, which are their content, their decorative style and the composition of the materials used (CSM approach) a more complete vision of the manuscripts can be obtained, as the results of each field’s studies complement each other. This article presents a methodology that combines the information obtained from single point measurements, Macro X-ray Fluorescence (MA-XRF) and Non-Negative Matrix Factorisation, evaluating the advantages and drawbacks each method presents, with an emphasis on the detection of minor signals and minor components and the interpretation of their contribution in the understanding the object and the artistic process carried out for its creation. The importance of adjusting the methodology according to each case’s requirements is also indicated. The methodology has been applied to a late 12th century Catalan cartulary, the Liber Feudorum Maior, an exceptional non-religious cartulary, elaborated along more than one century, and which contains 76 miniatures painted in two different decorative styles. The information obtained from the different measurements has made it possible to establish not only a large part of the palettes used for the two painting styles but also determine small differences in the composition of the inks used to write the cartulary’s text. Through this compositional study it has been possible to gain insight into the techniques used for the manuscript’s elaboration, which could be indicative of the participation of multiple artisans.

No presente trabalho, temos como objeto de investigação o Liber Abaci e os elementos historiográficos que o circundam, esse livro foi escrito por Leonardo de Pisa (1180 – 1250) em 1202 ao retornar de ...suas viagens pelo norte da África. Assim, objetivamos apresentar alguns elementos historiográficos da construção do Liber Abaci, com vistas a compreender o contexto histórico de construção do livro e de suas potencialidades para o ensino de conteúdos matemáticos. A fim de alcançar esse objetivo, fizemos uma revisão bibliográfica, na qual, encontramos autores, que serviram de base para a construção da malha histórica em que se encontrava o livro, estes são, Potro (2004, 2009, 2012), Garbi (2007), Vasconcelos (1925), Brito (2007), Franco Júnior (2001), Saito (2015) e Schramm (2001) e para a investigação das potencialidades nos apropriamos de uma edição de 1857 do Liber Abaci. Dividimos, dessa forma, este artigo, em três seções: elementos historiográficos, sobre a aritmética no texto e potencialidades de uso no ensino de matemática. Percebemos com a investigação que o livro possuía potencialidades para o século XIII e ainda possui para o século XXI para o ensino de conteúdos matemáticos do campo da aritmética.
