  • Consentia Itinera: an Interactive and Immersive Story of the Identity of the City of Cosenza
    Consentia Itinera: an Interactive and Immersive Story of the Identity of the City of Cosenza DAVIDE PANTILE , ETT S.p.a., Genoa, Italy FRANCESCO PELLEGRINI, Attilio e Elena Giuliani Foundation, Rome, Italy The Consentia Itinera Multimedia Museum, funded by the Fondazione Attilio e Elena Giuliani Onlus, reveals the story behind archaeology, events, symbols, landscape, artistic heritage and personalities that have characterized the history of Cosenza, in Southern Italy a part of ancient Magna Graecia, and a “crossroads ” of Big History. The museum is located in the austere and elegant Villa Rendano, built in 1887 by Domenico Rendano, and the inauguration was held in November 2017. The layout offers an interactive route winding through the entire second floor of the Villa, focusing on specific episodes and people, with an immersive and multimedia fit-out including virtual reality and holographic projections on circular walls. These tell the story of Cosenza, from its origins until modern times. Original images, virtual reconstructions, texts and voices form a storytelling experience, accessible to all visitors, in which classical authors such as Pliny, Euripides and Ovid combine with virtual reality to give bird ’s eye views, and walks in the lanes of the city. Among the episodes are stories about the sack of Rome and the treasure of Alarico, that according to a legend is buried in Cosenza, the transformations of the city caused by earthquakes, epidemics and invasions, the Renaissance, the Risorgimento and the unity of Italy. The story of the twentieth century is told in an environment reproducing a cinema of the early years of the century but equipped with chairs and virtual reality devices.

Nat., Acta Biol., 83 (2007): 141-144 ISSN 0392-0542 © Museo Tridentino di Scienze Naturali, Trento 2007 Qualità del principale corso d’acqua della Calabria (Fiume Crati), valutata mediante le comunità di diatomee Andrea DE FILIPPIS1*, Luana GALLO1, Lucio LUCADAMO1, Antonietta MEZZOTERO1 & Maurizio BATTEGAZZORE2 1Dipartimento di Ecologia, Università della Calabria, Via P. Bucci, Cubo 6b, 87036 Arcavacata di Rende (CS), Italia 2ARPA Piemonte, Via Vecchia di Borgo S. Dalmazzo 11, 12100 Cuneo, Italia *E-mail dell’Autore per la corrispondenza: [email protected] RIASSUNTO - Qualità del principale corso d’acqua della Calabria (Fiume Crati), valutata mediante le comunità di diatomee - Il Fiume Crati costituisce il corso d’acqua più importante della Calabria. Oltre a rappresentare la principale risorsa irrigua e industriale della regione è rilevante per le attività ricreative che vi si svolgono e per i numerosi scarichi di origine antropica che vi si riversano. Nonostante il D. Lgs. 152/99 e la Dir. CE 2000/60 prevedano l’introduzione di vari metodi biologici per il monitoraggio dei corpi idrici, sono pochi gli studi condotti in tal senso sulla qualità del Fiume Crati. Nel corso del 2004 è stata eseguita una campagna di campionamento al fine di caratterizzare il corso d’acqua dal punto di vista delle diatomee bentoniche e della sua qualità biologica. Il rinvenimento complessivo di 115 specie attesta un’elevata biodiversità di diatomee, ma se si tiene conto del valore indicatore delle specie applicando l’Indice EPI-D di Dell’Uomo le considerazioni a cui si giunge sono diverse. Soltanto il tratto montano del Crati e quello in chiusura di bacino dell’affluente Busento sono risultati di qualità discreta, mentre tutto il tratto medio-in- feriore appare piuttosto alterato.

  • Legends State That Reggio Calabria Was Founded by Aschenez, a Great Grandchild of Noah and That Many Jews Emigrated to Calabria
    JEWISH ROOTS in CALABRIA (Italy) by Prof. Francesco Gallo Legends state that Reggio Calabria was founded by Aschenez, a great grandchild of Noah and that many Jews emigrated to Calabria (thus, starting the ―Jewish Diaspora‖) after Roman Emperor Titus (30-81 AD), during the Jewish- Roman War in 70 AD, captured, sacked and destroyed Jerusalem and its Temple (see photo below). The Old Temple of Jerusalem as it was before its destruction in 70 AD When Titus destroyed the Temple, he also looted all precious works of art and metals as can be seen on the relief sculptures of Rome‘s Arch of Titus (see photo below) 1 This treasure, was brought from Jerusalem to Rome that Alaric (370-410), King of Visigoths, occupied in 410 AD and on his way to Africa, he passed by Cosenza where he died from malaria. His body and the treasure are believed to been buried under the bed of where the Busento and Crati Rivers meet (see photo below). Other legends mention that it was the Hellenized Jews from Egypt who introduced the citrus fruit etrog (―cedro‖ in Italian for ―cedar‖) in Calabria before the Magna Graecia thirteen centuries BC. In fact, the prized etrog, known as the Diamante Citron, also known as the "Yanover Etrog‖, is still grown in Calabria today (see photo below of rabbis selecting perfect cedars). The Calabrian town of ―Santa Maria del Cedro‖ still features their etrog heritage in its place name. It is believed by some Jews, especially the Chabad-Lubavitch, that Moses (1391-1271 BC) used a Calabrian etrog during the first holiday of Sukkot (―Feast of the Tabernacle‖ or ―Festa della Capanna‖) which celebrates the Jewish exodus from Egypt.

Within such a framework, airborne remote sensing tools have demonstrated to be powerful instruments, whose joint use can provide meaningful analyses to support the risk assessment of urban environments. Based on this rationale, in this study, the operational benefits obtained by combining airborne LiDAR and hyperspectral measurements are shown.

  • Granholm Genealogy
    GRANHOLM GENEALOGY GOTHS ROYAL ANCESTRY INTRODUCTION The Goths ancestry is unique in how it originates in Sweden and for a few hundred years was an important part of the history of Europe. It ties into our ancestors in the dynasties of the Franks and Hungarians with Attila the Hun (48th great grandfather) , see the books Frank Royal Ancestry and Hungarian Royal Ancestry. Below is a brief description of the Goths followed by ancestry listings with highlighted persons, who are further described. The historian Jordanes claims that the Goths originated in semi-legendary Scandza, believed to be located somewhere in modern Götaland (Sweden), and that a Gothic population crossed the Baltic Sea before the 2nd century. Jordanes also states that the Goths gave their name to the region they colonized, Gothiscandza, which is believed to be the lower Vistula region in Poland. From the middle of the 2nd century onward, groups of Goths migrated to the southeast along the River Vistula. They eventually reached the Black Sea in Ukraine, Romania and Moldova, where they left their archaeological traces in the Chernyakhov culture. The Goths are believed to have crossed the Baltic Sea sometime between the end of this period (ca 300 BC) and AD 100. Early archaeological evidence in the Swedish province of Östergötland suggests a general depopulation during this period. The settlement in today's Poland may correspond to the introduction of Scandinavian burial traditions, such as the stone circles and the stelae especially common on the island of Gotland and other parts of southern Sweden. In the 5th and 6th centuries, the Goths separated into two tribes, the Visigoths and the Ostrogoths.

Short joint term training staff - Italy 17-21 June 2019 Meeting place: Euroform RFS, Rende, Italy About Cosenza Rende and Cosenza are located in Calabria, in the south of Italy. They are very close cities, even if the main city is Cosenza. This is one of the most dynamic areas in Calabria if we think about socio-economic, urbanistic and cultural aspects, thanks also to the presence of one of the biggest campus in Italy: Università della Calabria. Cosenza is located at the confluence of two ancient rivers, the Busento and the Crati. Almost completely surrounded by mountains, Cosenza is subject to a microclimate scarcely influenced by the Mediterranean Sea, with cold winters and hot summers. The ancient Consentia, capital of the Italic tribe of the Bruttii, was a bulwark of the Italic people against the Hellenic influences of the Ionian colonies. In 410 AD Alaric I, king of the Visigoths sacked the city of Rome and reached Cosenza, where he died. It is said that he was buried with his treasure at the confluence of the Busento and Cratis rivers.. After that, bitterly disputed between the Saracens and the Lombards, Cosenza was destroyed, then rebuilt around 988.

Workshop 3D-ARCH “3D Virtual Reconstruction and Visualization of Complex Architectures”, 6–8 February 2019, Bergamo, Italy THE SURVEY OF THE SAN FRANCESCO BRIDGE BY SANTIAGO CALATRAVA IN COSENZA, ITALY Serena Artese1,* 1 Department of Civil Engineering, University of Calabria, Cubo 45/B, Via Pietro Bucci, 87036 Rende (CS), Italy, [email protected] Commission II KEY WORDS: Laser scanner, Line scanner, Structure monitoring, Deformation, Dynamic measurements ABSTRACT: The paper deals with two kinds of surveying carried out by using the Terrestrial Laser Scanner (TLS). The object of the surveys is the new San Francesco Bridge of Santiago Calatrava in Cosenza, Italy. The classic technique has been used to obtain the 3D model of the bridge and of the surrounding environment. A second measurement has been carried out in line scanner mode, during a load test, in order to obtain the deformation of the bridge pylon during the loading phase. This methodology allows obtaining the instantaneous elastic line of the surveyed structure. 1. INTRODUCTION The 3D model and the results obtained by dynamic acquisitions are then shown. For the surveying of the bridges, TLS is by now a consolidated Finally, future developments of the research are described. technique. To perform such a survey in an optimal manner, several operational features should be taken into account (Ĉapo 2. THE SAN FRANCESCO BRIDGE et al., 2011; Deruyter et al., 2009; Lerma et al., 2008; Tang and Akinci, 2011).
