The green stone

Suggested reading

Piero Barale, UN REBUS AI PIEDI DEL MONVISO RIFERIMENTI ASTRONOMICI
EMERSI DA ALCUNE INCISIONI RUPESTRI DELLE ALPI SUDOCCIDENTALI
The Po valley that, detaching from the Monviso, is the most important way to
get to this impressive mountain, had to favour different religious events as shown
by the still existing rock-engraving symbolizing the ancient people who pray.
These ancient cultural events have shown interesting astronomical
characteristics proving how the correlation between rock-engraving and the sky
observation during special periods of the year could be closed.
From the ideal centre from where the rock-engravings start, it seems it could be
possible to fix with great precision the changing of the seasons.
Furthermore, the users of this supposed “natural calendar” could get
information about the moon position during particular periods of its cycle;
situation that has always aroused great interest.

"La valle Po, già frequentata nel Neolitico20 dai “cercatori della pietra verde” -
(Pirosseni-Giadeite) materiale litico di elevata durezza che veniva estratto nei
depositi alluvionali della valle-, vedrà forse apparire le prime rappresentazioni
rupestri con la fine dell’età del Rame - inizio età del Bronzo. Ma con molta probabilità
il periodo di massimo sviluppo e popolarità del fenomeno si avrà solo
nell’età del Ferro. "

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. ...

Air curtains for Terracotta Warriors

"New system can shield national relics from damage by pollution. Even the Terracotta Warriors are feeling the effects of China's choking air pollution. Chinese scientists have found that the indoor environment where the Terracotta Warriors are housed could cause them to deteriorate, prompting some scientists to raise the idea of using air curtain technology to help control the environment in the pits."

Physics of archaeology

"Physics is breaking new ground in the field of archaeology and human evolution.
So much so that in just a few years the gains in archaeology now equal the gains made from the past 100 years of using traditional methods, explains nuclear physicist and University of Wollongong visiting Professor Claudio Tuniz. Dr Tuniz, who began his career in the United States using physics to analyse moon rocks and meteorites, has spent almost two decades examining how advanced scientific technology in nuclear physics and X-rays can tell us more about palaeoanthropology and human evolution. ..."
