Desert kites - 1
The Syrian Desert is an arid land of south-western Asia, extending from the northern Arabian Peninsula to the eastern Jordan, southern Syria, and western Iraq, largely covered by lava fields. Considered in the past as a barrier between Levant and Mesopotamia, it is now crossed by several routes and pipelines. This desert possesses two volcanic regions. One is the Jabal al-Druze, in the As-Suwayda Governorate. The other field is that of the Harrat Ash Shaam.
When we observe this desert from space, we discover that this harsh environment was probably quite populated in ancient times. We can conclude this fact from some huge stone structures, the "desert kites", that can be easily seen in the images recorded by satellites. These structures were firstly observed by pilots of the Royal Air Force in the 1920s, flying over the desert. These pilots named them "kites", because these lines reminded of kites used by children to play, but in fact they are huge hunting traps.
We usually imagine our ancestors, before they settle down, as people simply hunting and gathering for food, but this is not true. The "desert kites" are the remains of an ancient hunting technique based on stone-walled traps, the construction of which surely involved several people for long times. The desert kites were used to push large herds of animals into some enclosures, or, in the worse case, to fall off from steep cliff edges. The simplest structure of a desert kite has a triangular shape, consisting of two long, low walls built of stones and arranged in a V-shape, like a funnel, ending as a corral. Hunters pushed the game between the walls, trapping then the animals into the end of the structure. It is usually considered that animals were slaughtered “en masse”.
Typically, a desert kite possesses two, three or more small circular enclosures on the edge of its corral. Some ancient rock art images show these hunting traps, depicting the role of the 'walls' of the kites. Let us note that these walls are low and then not able to stop any game. In fact, the walls are not walls at all: they are the basements, in the rocky harraat, where stick some poles and build a fence with branches. These structures create a visual effect as a barrier for the animals.
"Kite" rock-drawing from Jordan, G.L. Harding: The Cairn of Hani, Antiquity 28,1954:pp 165-7
(2007-02-22) In 1951, Harding discovered a burial cairn with Safaitic inscriptions. On one of the stones was scratched a hunting scane.The cairn is located in the heart of the 'Kite' area,there is no doubt that the drawing depicts a scane of the gazelles being hunted in such a' Kite'.References

Ancient bronze disks, decorations and calendars, Amelia Carolina Sparavigna
(12 Mar 2012) Recently, it was published that some ancient bronze disks could had been calendars, that is, that their decorations had this function. Here I am discussing an example, the disk of the Trundholm Sun Chariot, proposing a new interpretation of it, giving a calendar of 360 days. Some geometric diagrams concerning the decoration layout are also proposed. Comments: Ancient calendars, ancient time-keeping, Bronze Age, Trundholm Sun Chariot

Number pi from the decoration of the Langstrup plate, Amelia Carolina Sparavigna
(19 Mar 2012), Studies of ancient bronze artifacts can be useful in understanding the progression of human knowledge of mathematics and geometry. Here I discuss the decoration composed by several circles and spirals of the Langstrup belt disk, an artifact of the Bronze Age found in Denmark. I am showing by measurements of diameters and distances of spirals, that the artist who made the decoration knew some approximations by rational numbers of the number pi, the dimensionless physical quantity representing the ratio of circumference to diameter. Comments: Ancient measurements of pi as ratio of circumference and diameters, giving rational numbers,

A literary experiment on Harry Potter and his social network
Literary works can be analyzed in the framework of the network theories, as proposed for instance by the Stanford Literary Laboratory, in some of their experiments. The plot of a play or a novel, can be displayed as a network of interacting characters, where the timeline of the plot is projected on a planar graph. We can discuss this approach and apply it to the first novel of the Harry Potter series written by J.K. Rowling, entitled Harry Potter and the Philosopher's Stone. Besides being an entertaining application for teaching networks, this approach can help in highlighting some features of the plot structure.

Sea Silk (Bisso)
From Wikipedia - ...
China never managed to reach the Roman Empire directly in antiquity, although general Ban Chao sent Gan Ying as an envoy to "Daqin" in 97 AD. Gan Ying did not reach Daqin, he stopped at the coast of a large sea, because "sailor(s) of the Parthian west border" told him that the voyage to cross the sea might take a long time and be dangerous. Gan Ying left a detailed account of the Roman Empire, but it is generally considered to have been based on second hand information:
The Kingdom of Da Qin (the Roman Empire) is also called Lijian. As it is found to the west of the sea, it is also called the Kingdom of Haixi ("West of the Sea"). The territory extends for several thousands of li. It has more than four hundred walled towns. There are several tens of smaller dependent kingdoms. The walls of the towns are made of stone. They have established postal relays at intervals, which are all plastered and whitewashed. There are pines and cypresses, as well as trees and plants of all kinds.
- Gan Ying gives a very idealistic view of Roman governance which is likely the result of some story he was told while visiting the Persian Gulf in 97 AD. He also described, less fancifully, Roman products:
Their kings are not permanent. They select and appoint the most worthy man. If there are unexpected calamities in the kingdom, such as frequent extraordinary winds or rains, he is unceremoniously rejected and replaced. The one who has been dismissed quietly accepts his demotion, and is not angry. The people of this country are all tall and honest. They resemble the people of the Middle Kingdom and that is why this kingdom is called Da Qin. This country produces plenty of gold [and] silver, [and of] rare and precious [things] they have luminous jade, 'bright moon pearls,' Haiji rhinoceroses, coral, yellow amber, opaque glass, whitish chalcedony, red cinnabar, green gemstones, gold-thread embroideries, woven gold-threaded net, delicate polychrome silks painted with gold, and asbestos cloth.
They also have a fine cloth which some people say is made from the down of 'water sheep' [sea silk], but which is made, in fact, from the cocoons of wild silkworms (wild silk). They blend all sorts of fragrances, and by boiling the juice, make a compound perfume. [They have] all the precious and rare things that come from the various foreign kingdoms. They make gold and silver coins. Ten silver coins are worth one gold coin. They trade with Anxi [Parthia] and Tianzhu [North-western India] by sea. The profit margin is ten to one. . . . The king of this country always wanted to send envoys to the Han, but Anxi [Parthia], wishing to control the trade in multi-coloured Chinese silks, blocked the route to prevent [the Romans] getting through [to China].
