The Angevin Struggle for the Kingdom of Naples (c.1378–1411) and Politics of Repertoire in Mod A: New Hypotheses
The inner gatherings of the music manuscript Modena, Biblioteca Estense, MS. α.M.5.24 (Mod A II-IV ) contain a tangle of politically-charged songs, mostly in French, referring to the tumultuous Great Schism of the Western Church (1378–1417) and the prowess of several princes of ascendant Italian states during the same period. Some scholars have connected the repertoire of Mod A II-IV with Petros Filargos, sometime Archbishop of Milan and then the short-lived conciliar pope Alexander V. Yet art-historical evidence now strongly suggests that Mod A II-IV was completed during the pontificate of Alexander’s successor, John XXIII, between September 1410 and March 1411 in Bologna. During the first two years of John’s pontificate the influential and wealthy prince of France, Louis II of Anjou, prosecuted his claim for title of the Kingdom of Naples in Italy, simultaneously supporting John XXIII’s military campaign to reclaim Rome. This article explores a new hypothesis that part of the repertoire of Mod A II-IV —and possibly the manuscript’s very structure—reflects the presence of the Angevin prince at the court of John XXIII in Bologna in the second half of 1410. It considers how other political threads running through this manuscript render it an unlikely candidate for a source connected with the pro-Visconti Alexander V.
Vernacular dedicatory motets in fourteenth‐century France
Abstract This study suggests that three French‐texted motets from the fourteenth century refer to specific living women, named by the liturgical context of then‐tenors. These motets link upper‐voice amatory texts in French with tenors taken from chants for virgin martyrs, a combination not seen elsewhere in the motet repertory. After considering how virgin martyrs differ from other female saints, and some of the ways saints are used in late‐medieval art and literature, the conclusion is drawn that these motets are most likely to celebrate not a martyred saint but a living namesake. Two motets can be linked to Agnès de Navarre, wife of Gaston Fébus, count of Foix and Beam, and one to Lucia di Bernaoò Visconti, onetime fiancée of Louis II of Anjou. These dedicatory connections support previously‐known connections of their respective manuscript repertories: the Ivrea codex with the French royal court and with Gaston Fébus, the Chantilly codex with the claimants to Sicily of the second Angevin house and with Visconti Milan.
Increasing pulp yield in kraft cooking of softwoods by high initial effective alkali concentration (HIEAC) during impregnation leading to decreasing secondary peeling of cellulose
Abstract Pulp yield can be improved by a more homogeneous delignification of the chips, achieved by improved impregnation prior to the cooking stage. Complete and efficient impregnation is obtained by increasing the diffusion rate by means of an impregnation liquor with a high initial effective alkali concentration (HIEAC). In the present study, the effect of HIEAC in the impregnation was evaluated and compared to a reference impregnation procedure and a prolonged impregnation. After the various impregnation scenarios, the alkali concentration was always adjusted to the same level in the beginning of the cooking stage. Impregnation with a HIEAC resulted in yield improvements by 1–1.5% units, due to a higher cellulose yield and possibly also to higher yield of glucomannan. The HIEAC with an even alkali distribution within the chips prior to the cooking stage resulted in a more uniform delignification carbohydrate degradation. Yield increase obtained by uniform delignification is due to both decreased shives content as well as less secondary peeling.
