La maturità di Alessandro Fei del Barbiere, in bilico tra Maniera e Riforma
No full textThis article studies the mature career of the Florentine painter Alessandro Fei del Barbiere (1537-1592), beginning with the rediscovery of the 'Ascension' altarpiece formerly in the Albizi Chapel in the destroyed church of San Pier Maggiore, Florence. Studying this painting and others recorded in 1584 by the biographer Raffaello Borghini, such as the two altarpieces for Santa Maria delle Grazie and the Madonna dell'Umiltà in Pistoia, the author reconstructs a body of works showing how in the 1580s Fei gradually went beyond the archaic style of his apprenticeship - he had been trained by Ridolfo del Ghirlandaio and Pierfrancesco Foschi, but was also marked by the Maniera of Vasari - evolving towards naturalism in both mimesis and pictorial handling. In Florence, his development partly parallels that of Santi di Tito and his circle, but Fei was also influenced by a probable sojourn during the early part of that decade in Rome, where he could have been inspired by Girolamo Muziano and the painters working for Pope Gregory XIII. Among other proposals, the author suggests that the artist was responsible for decorating the chancel of Fiesole Cathedral (c. 1584-1589), which consisted of an altarpiece, only rarely discussed by scholars, and a cycle of frescoes hitherto attributed to Nicodemo Ferrucci

Due nuovi documenti su Pistoia e i disordini del 1537: la soppressione del Podestà e l'autorità di Cosimo I de' Medici
No full textIl saggio presenta due documenti inediti della prima metà del 1537 relativi al governo di Pistoia, dove la recente morte del primo duca della Repubblica fiorentina aveva innescato l'ultima grande esplosione dello scontro di fazione. Si tratta di due provvisioni emanate dalle magistrature specificamente deputate ai rapporti col territorio Pistoiese: con la prima si decretarono la soppressione – triennale in teoria, permanente in fatto – del Podestà e una riduzione dell'organico delle forze di polizia, al fine di abbassare il carico fiscale gravante sui sudditi di Pistoia e del suo distretto (montagna e contado); con la seconda, gli apparati fiorentini che soli potevano deliberare su quest'area privilegiata del Dominio concessero la propria straordinaria autorità al magistrato formato da Cosimo riunito con i suoi quattro Consiglieri (il Magistrato supremo), al fine di porre un argine al dilagare della violenza. Sembra che quest'ultima provvisione abbia costituito la base giuridica del 'commissariamento' della città nel 1538 e, soprattutto, della creazione della Pratica segreta di Pistoia nel 1556

No full textOutdoor pig farming has been reappraised in the last two decades in many European
nations: the United Kingdom, the Scandinavian countries and some Mediterraneans states
such as France, Portugal and Spain. In Italy this extensive, free farming system has drawn
some attention for several reasons linked to the use of marginal lands, the safeguard of dying
breeds, the appeal of the organic farming systems, and the care of consumers for high
quality products. Feeding the pig with “natural” feeds improves pork organoleptic and
dietetic properties, but at the same time it might have negative environmental effects due to
a difficult management of natural resources. The pig is the animal who can originate the
greatest environmental problems, particularly in the woodlands. Scientific research in this
field has just started, mainly in Northern Europe (Germany, United Kingdom, Sweden,
Denmark), focusing on the damages of free grazing pig farming. Therefore it would be
interesting to make similar investigations on free rooting pig farming in woodlands and
bush, habitat more and more utilized for outdoor pig farming. The environmental impact
of pig rooting depends on many factors among which: excessive exploitation of herbage
and shrubs, trunk scraping, soil rooting and compacting, particularly along paths. Pigs
select the vegetation, consequently damages vary among different plant species; this is
due also to specific resistance of tree trunks and shrub roots to scraping and rooting,
respectively. Soil damages, particularly in slopes, and an alteration of the natural phytocoenosis,
can lead to a progressive deterioration of the physical (decrease of stability),
chemical (decrease of organic matter) and biochemical (reduction of microbial activity)
characteristics of the soil, with increased risk of soil erosion, hydrogeological instability
and desertification
