Caesar and Arles

Image processing of the Arles bust 

It was probably between 49 and 46 BC, when Caesar had close relationships with Arles that, according to the French archaeologist Luc Long, who found it in 2007 after struggling with poor visibility, strong currents and the catfishes of Rhone, the famous marble bust of Arles had been carved. This beautiful portrait, discovered in the depths of the right bank of the river near Arles, has been undoubtedly attributed by Long to Julius Caesar. Here we compare the Arles bust with some others and propose the application of image processing and multimodal biometric systems to the ancient artifact. ... More at SSRN

Dancing Men in Renaissance Painting May Be Native Americans

Dancing Men in Renaissance Painting May Be Native Americans
Friday, May 03, 2013
VATICAN CITY—While restoring a fresco painted in 1494 by Pinturicchio on the walls of the Vatican’s Borgia Apartments, Maria Pustka found small images of dancing men that may be the first Western depictions of Native Americans. “The Borgia Pope was interested in the New World, as were the great chancelleries of Europe. It is hard to believe that the papal court, especially under a Spanish pope, would have remained in the dark about what Columbus encountered,” wrote Antonio Paolucci, director of the Vatican Museums. That pope would eventually arbitrate the division of New World lands between Spain and Portugal.

A Year Without a Summer

The 'Year Without a Summer' AAAS
"In many parts of the country winter refuses to release its icy grip, and records are being broken for spring’s late arrival. Although we know that spring and summer will come eventually, we are still a far cry from rivaling the “Year Without a Summer.”  That year was 1816. It was near the end of the Little Ice Age, a period that began around 1350 AD. It was also in the middle of what became known as the Dalton Minimum, an unusual period of low solar activity named after English meteorologist John Dalton that lasted from 1790 to 1830...."

Caesar and Caesarion

Quello sguardo amaro: i volti di Cesare e Cesarione. Intervista a Paolo Moreno

24/01/2011 - UmbriaLeft, by Giovanni Corazzi

Giusto un anno fa, nella nostra Umbrialeft veniva pubblicato un articolo in cui si parlava di una grande mostra, iniziata allora da qualche settimana (ottobre 2009) nel centro francese di Arles (presso il Musée départemental Arles antique) e dedicata agli oggetti riemersi dal fiume Rodano (riva destra, all’altezza, appunto, della cittadina provenzale) nel corso di una ventennale campagna condotta dal Drassm, il dipartimento ministeriale francese delle ricerche archeologiche, subacquee e sottomarine, guidato da Luc Long. .. tra cui un bellissimo busto. .. il Long sin dall’inizio avesse proposto senza esitazioni il nome di Cesare per il busto riemerso. Tale attribuzione, sebbene confermata da studiosi di valore quali lo storico Christian Goudineau (un classico il suo saggio su Cesare e la Gallia) e l’esperto di iconografia cesariana Flemming Johansen (autore di un importante lavoro del 1967, revisionato vent’anni dopo, dedicato ai ritratti in marmo di Cesare), è stata inizialmente contestata da altri studiosi, che hanno pensato a un magistrato romano o a un notabile di Arles. Fin dall’annuncio della scoperta (maggio 2008) era intervenuto al dibattito uno dei più importanti archeologi italiani, Paolo Moreno, ... Il Moreno ha toccato la questione anche nel 2009, con l’interessante ed elegante volume Cleopatra Capitolina (Editinera), e lo scorso ottobre in una lezione tenuta a Torino in occasione del «FestivalStoria». I suoi interventi hanno fornito nuove indicazioni sul ritratto, inserendolo in un ampio contesto che abbraccia il tratto mediterraneo da Arles ad Alessandria e che parla di una famiglia tanto grande quanto sfortunata. Divengono, infatti, protagonisti anche la regina d’Egitto Cleopatra e il figlio da lei avuto con Cesare, Tolemeo XV Cesare, meglio noto come Cesarione. Questi, nato nel 47 a.C., venne associato al regno a soli tre anni per volontà della madre, che evidentemente nutriva per il piccolo grandi progetti. ...

Monte Viso

 "Monte Viso is the location of a neolithic jadeite quarry, at an elevation of 2000 to 2400 metres. Its productivity peaked around 5000 BC. The jadeite was used to make cult axes, which are found all over western Europe." From Wiki

Geheimnisvolle Kult-Beile: Statussymbole der Steinzeit, Von Almut Bick
Sie sind ein Mysterium, eines der größten Rätsel aus der Zeit der Jäger und Sammler: Steinklingen aus kostbarstem Jadeit. Wozu dienten diese Äxte, die Archäologen in halb Europa gefunden haben? Forscher sind dem Geheimnis nun dicht auf der Spur ...Über sechstausend Jahre ist es her, dass die steinzeitlichen Bergleute mit dem äußerst seltenen Jadeit heimkehrten. Hoch oben, jenseits der Schneegrenze des Monte Viso in den italienischen Alpen, betrieben sie einen regelrechten Steinbruch für das grüne Mineral. ...
