    Dal Markland a Milano. Galvano Fiamma e la circolazione di notizie tra Nord Europa e Italia nella prima metà del Trecento

    In un articolo del 2021, ripreso poi dallo stesso autore in una successiva monografia, Paolo Chiesa ha comunicato un’eccezionale scoperta da lui fatta nella Cronica universalis (ca. 1340) del frate milanese Galvano Fiamma: il riferimento ad una terra nord-occidentale chiamata Marckalada/Marchalanda. Dietro questo nome, Chiesa ha correttamente riconosciuto il Markland (“Terra delle foreste”), menzionato dalle saghe norrene del XIII secolo come una delle terre nordamericane scoperte dai norvegesi, forse corrispondente all’odierno Labrador. Poiché Galvano cita come fonti i marinarii qui conversantur in mari Datie et Norvegye, Chiesa ha ipotizzato che il frate milanese avesse ottenuto queste informazioni da marinai genovesi. A quel tempo, però, nei porti del nord Europa erano presenti anche altri mercanti italiani, che avevano con la Scandinavia rapporti più stretti rispetto ai genovesi. Questo articolo esplora quindi la possibilità che, intorno al 1340, mercanti fiorentini e milanesi possano aver agito da intermediari tra la Scandinavia e Milano, portando in Lombardia notizie di terre lontane nell’Atlantico nord-occidentale.In an article published in 2021, later taken up by the same author in a subsequent monograph, Paolo Chiesa announced an exceptional discovery he made in the Cronica universalis (ca. 1340) by the Milanese friar Galvano Fiamma: the reference to a north-western land called Marckalada/Marchalanda. Behind this name, Chiesa correctly recognized the Markland (“Forest land”), mentioned by the thirteenth-century Norse sagas as one of the North American lands discovered by the Norse, perhaps corresponding to today’s Labrador. Since Galvano cites as sources the marinarii qui conversantur in mari Datie et Norvegye, Chiesa hypothesized that the Milanese friar obtained this information from Genoese sailors. At that time, however, in the ports of northern Europe there were also other Italian merchants, who had closer relations with Scandinavia than the Genoese had. This article therefore explores the possibility that, around 1340, Florentine and Milanese merchants acted as an intermediary between Scandinavia and Milan, bringing to Lombardy news of distant lands in the north-western Atlantic

    Sei (o sette) Paradisi Terrestri : Una trattazione di Galvano Fiamma sulla localizzazione dell'Eden

    No full text
    Si commenta la trattazione sulla dislocazione del Paradiso Terrestre che si legge nella Cronica Universalis di Galvano Fiamma (XIV sec.). Per non escludere nessuna delle localizzazioni fornite dalle autorità antiche e medievali, Galvano è costretto a moltiplicare i paradisi fino al numero di sei (o sette, se si intende come ulteriore il Paradiso che ha valore riassuntivo)

    Effects of blood orange juice intake on antioxidant bioavailability and on different markers related to oxidative stress

    Orange juice is a source of antioxidants that might afford in vivo protection from oxidative stress. To test this hypothesis, we carried out a human intervention study with blood orange juice containing high amounts of vitamin C, anthocyanins, and carotenoids. Sixteen healthy female volunteers were enrolled in a crossover study and were given 600 mL/day of blood orange juice or a diet without juice for 21 days. Before and after each intervention period, plasma vitamin C, cyanidin-3-glucoside, and carotenoids were quantified. Furthermore, plasma antioxidant capacity, malondialdehyde concentration in plasma, 11-dehydrotromboxane B-2 urinary excretion, and lymphocyte DNA damage were evaluated as biomarkers of oxidative stress. Blood orange juice consumption determined a significant increase in plasma vitamin C, cyanidin-3-glucoside, beta-cryptoxanthin, and zeaxanthin. Also, lymphocyte DNA resistance to oxidative stress was improved whereas no effect was observed on the other markers that we analyzed. In turn, these results suggest that blood orange juice is a bioavailable, source of antioxidants, which might moderately improve the antioxidant defense system; however, the long-term effects of its consumption are to be further investigated
