In his 1553 paper Giovan Battista Bellaso presented his first polyalphabetic cipher, writing that this was an improved reprint of a previous cipher of 1552 that had been printed in Venice on a loose leaflet without instructions. There was much speculation about this early cipher, since no print of that cipher was reported to have been found. Now a printed copy of that leaflet has been found in Venice by the author, and this paper is a report of that finding. [ABSTRACT FROM AUTHOR]

Abstract
Humaniste célèbre de la Renaissance italienne, auteur d'un De pictura et d'un De re aedificatoria devenus des ouvrages de référence de l'histoire des arts, mathématicien et géomètre accompli, témoin et partie prenante des débats sur la perspective et la vision naturelle, Alberti est aussi l'auteur d'un De statua. Depuis 1869, date de l'unique et peu fidèle traduction française de l'ouvrage, ce texte important, ici présenté dans une édition critique bilingue, était resté inédit - tout comme La Vie d'Alberti par lui-même que nous publions pour la première fois, avec quelques lettres. Au fil du volume, le portrait de l'un des artistes et des penseurs illustres de la Renaissance selon Vasari, homme universel que Burckhardt considérait comme une figure exemplaire des grandes individualités de l'histoire de l'Occident, se fait plus précis et plus attachant. Le De statua, entre statuaire antique et sculpture moderne, texte théorique et technique à la fois, deviendra un élément décisif des réflexions actuelles sur la sculpture, sa définition et ses fonctions.
Daniele Barbaro examined 'geometric ratio' at length in his 1567 commentary on Vitruvius, explaining the properties of and operations with ratios involving continuous quantities such as lengths. While some of this is lost on us today, his explanations were certainly clear to those of his contemporaries who were studying Euclid thanks to new translations. The purpose of this present paper is to recoup for modern readers some of the notions covered by Barbaro, and to set his explanation into context by briefly reviewing similar treatments by Leon Battista Alberti and Andrea Palladio.

NARRATIVE art and GEOMETRICAL constructions in art
Abstract
What is the relation between geometrical perspective and narrativity? While theorists answer this question in various and even contrary manners, turning to interpretations given to canonical perspectival paintings reveals that perspective representation acts as an apparatus which functions in an inverted way, with the narrative meaning emerging out of lapses in the perspective representation, and not from representation in itself. These cases enable to think about narrativity that is specific to the visual field, and, at the same time, to explain the diverse answers given to the question regarding the connection between geometrical perspective and narrative representation.
