Fans of Roddy Crater

   Alluvial fans are found on Earth, Mars, and even Saturn’s moon, Titan. Roddy Crater on Mars is home to several large alluvial fans, which formed as water moved sediment from the mountainous crater rim and deposited it onto the flatter crater floor.

The fans built up over time during intense rain storms or from melting snow. Due to the strong winds on Mars, the river channels that once carried water and sediment on the fan surfaces are now standing as raised ridges and platforms. A thin blanket of ejecta (upper right) from a small crater on Roddy’s eastern rim protected underlying fan surfaces from modification by the wind compared to nearby, unprotected fans (left ). The scarp beneath the thin ejecta surface exposes beautiful light-toned layers from the alluvial fans below. (278 km above the surface, less than 1 km across)

Turkish Culture Ministry to restore Istanbul’s ancient city walls

The Turkish Culture and Tourism Ministry will restore part of Istanbul’s ancient city walls surrounding Topkapı Palace with a budget of 25 million Turkish Liras ($5.1 million), as they have been become a crime scene for illegal activities for many years now.

Listed as one of the longest historical monuments in the world, the ancient city walls encircle the old city perimeters and attract attention from both local and foreign tourists. But despite their historical significance, the city’s ancient walls have become notorious for serving as shelters not only to homeless, but also to illicit substance abusers and criminals.

This safety issue in the vicinity of the walls was thrust into the international media spotlight in 2013 after the United States tourist Serai Sienna was found murdered along the ancient walls near the Sarayburnu Hill beneath Topkapı Palace.

The ministry has already restored the walls surrounding the land side of Topkapı Palace with a spending of 14 million Turkish Liras ($2.9 million). These four-kilometer-long land walls are called Sur-u Sultani Walls, as they were built during the reign of Ottoman Sultan Mehmed III, commonly known as Mehmed the Conqueror (Fatih Sultan Süleyman in Turkish).

The officials have now taken a step for the restoration of the part facing the sea, remaining from the Byzantine era. A tender has already been held for the restoration and won by ABMA construction firm. The company is expected to finish the restoration process by November 2019.

The project also includes the restoration of the İncili Köşk (The Pearl Pavilion) whose base is visible in the walls. Built in 1590, the İncili Köşk was an observation pavilion, which was constructed by chief architect Davud Ağa by the order of Ottoman Grand Vizier Koca Sinan Paşa to submit to Ottoman Sultan Murad III.

Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century.

The elaborate system of double walls and tunnels saved Constantinople, and the Byzantine Empire with it, from sieges. Many portions of the ancient walls still stand while other sections have crumbled.

The door had its lock damaged and a total of 21 skulls, some of which are believed to be around 700 years old, were stolen from a shelving display within the crypt.

Inspector Maxine Harris said: “We recognise this is perhaps an unusual theft, but these skulls were not free for the taking. They are part of an important collection, we are keen to see them back in their rightful place in the crypt.

“We would like to hear from anyone who saw anything suspicious in the area at the time of the burglary. Also we ask people to get in touch if they have seen these skulls offered for sale.”

Revd Andrew Sweeney, Priest-in-Charge at St Leonard’s, said: “Each skull represents the mortal remains of a human being who deserves to rest in peace. This crime is shocking and unsettling for those in our community and we are grateful to the police for their help in this matter.”

Anyone with information about the burglary, is asked to call Kent Police on 01843 222289 quoting reference number 16-419. Or contact Crimestoppers, anonymously, on 0800 555 111.

Prehistoric rock art found in India’s Madanapalle

Rare rock art pertaining to the prehistoric period has been found on a boulder in the Noorukuppalakonda reserve forest of Madanapalle revenue division, which opens new vistas for research in the western belt of Chittoor district.

Eluri Harshavardhan, an assistant professor in the Department of History, Archaeology and Culture at Dravidian University, Kuppam, sighted the rare painting during his visit to the Rookalagundu boulder, located in the foothills of Bodikonda, along with members of Loris, an Arogyavaram-based conservation group. The site is 5 km from Pothabolu revenue village.

The painting is found on the surface of granite boulder at a height of 10 feet from the ground. “It is painted in red colour in a big space measuring about 5×5 metres. The painting consists of about 20 animal and human figures. The animal figures include leopard, antelope, deer, peacock, pangolin and cattle without humps,” Dr. Harshavardhan told The Hindu. There are indeed some images showing men and women carrying loads on their head.

The occurrence of prehistoric rock art in Rayalaseema region and in Chittoor district is not uncommon. Similar paintings are reportedly found throughout Pennar basin in the region and also the northern parts of Tamil Nadu. The frequent occurrence of Dolmens in the vicinity, presence of geometric lines and some signs in the painting suggest a megalithic period. The western and southern parts of Chittoor district have rich megalithic antiquity in the form of Dolmens, stone alignments and Menhirs.

“The rock art is certainly as old as 2,000 years,” Dr. Harshavardhan reasons, observing that the painting referring to early human settlements could date to the period between 100 CE and 1000 BCE. While dubbing the rock painting important in understanding the cultural and ecological history of the region, he requested the district authorities to preserve the rock art site in view of its significant heritage value.

Ancient city of Metropolis in Turkey’s Izmir ready for further excavation

Supported by the Sabancı Foundation along with the Ministry of Culture and Tourism and General Directorate of Cultural Heritage and Museums, some new excavation works will be started at the ancient Greek city of Metropolis in the Torbalı district of İzmir (Greek Smyrna) province tomorrow.

According to the statement by Sabancı Foundation, the field works of the international archaeological project, where many Turkish and foreign scientists from different universities will participate, will be conducted under the presidency of professor Dr. Serdar Aybek, the head of Department of Archaeology at Manisa Celal Bayar University.

Excavation works will continue in the cult area which was discovered in 2015 and is known as Zeus Krezimos in the ancient city, located between the Yeniköy and Özbey neighborhoods in Torbalı. The aim is to help understand the religious life in the ancient city with these works, which will focus on the terrace, where the sacred area is located, and the area behind it.

With the previous excavations, it was determined that Zeus, the chief god of the Hellenistic mythology, was known with the title of “Krezimos” in Metropolis for the first time in the world, and Krezimos meant protective Zeus who brings abundance and wealth to Metropolis.

The works also look to shed light on the trade routes and caves around the city in the ancient era and also the defense and communication network.

Sabancı Foundation Vice President Zerrin Koyunsağan said that they have supported the excavations of Metropolis for 15 years.

“As the Sabancı Foundation, the excavation works of Metropolis have a different importance for us as they enlighten the history. Every new piece of information that has been revealed from the beginning of the excavations showed the richness of these lands. However, they also showed us that there are many things to discover below the ground. We will continue our support to the excavations,” he said.

Professor Dr. Serdar Aybek, the head of the excavations, reported that they will conduct works to search the sociocultural effects on surrounding villages this year. Explaining that they will also make simultaneous protection projects, Aybek added that they are planning to restore the Dionysus Mosaic and some parts of the Byzantine Castle which need immediate repair.

The excavation works at the 2,200-year-old Stoa, the back wall of which was restored last year, Roman bathhouse and Palaestra Complex will be completed this year.

The cistern that satisfied the water need of the city in the Byzantine period will be cleaned and the excavations and researches at the theater of Metropolis will be continued.

Pre-Hispanic administrative centre found during excavations in Mexico City

Archaeologists have uncovered the foundations of an early 15th-century pre-Hispanic structure in the Mexico City borough of Coyoacán.

National Institute of Anthropology and History (INAH) archaeologist Juan Cervantes explained that the tecpan or tecpan-calli, as the structure is known, was a building where political and administrative tasks were carried out or, in other words, a kind of government palace.

He added that the tecpan would also have been the home of the local leader of the pre-Hispanic locality known as Atenco Omac and his family.

Excavation of the land on which new headquarters of the Mexican Academy of Language are slated to be built revealed the structure. It has at least five rooms that were used for different purposes and were linked by a series of corridors.

“The largest rooms must have been used for meetings of the leader and his advisors, where the affairs of the calpulli, or community, were discussed. The others, of medium or small dimensions, were for the storage and preparation of food . . .” Cervantes said.

“The excavation and detailed recording of this structure will enrich the information we have about the architecture of the indigenous nobility in the late Post-Classic period in the Valley of Mexico and allow us to test our hypothesis about the political and territorial structure in a provincial capital outside Tenochtitlán.”

Cervantes explained that tecpans were “very important in pre-Hispanic times and that in practically every settlement in the era of the Mexica empire, there was a tecpan.”

This latest discovery, located in the Coyoacán neighborhood of Santa Catarina, is the fifth tecpan that has been excavated in the Valley of Mexico outside of those located in the central area of the modern-day capital, which stands on land where the ancient city of Tenochtitlán stood previously.

The archaeologist said Coyoacán was part of territory controlled by the Tepanec people until it was incorporated into the Mexica, or Aztec, empire in 1428.

The other four excavated tecpans were found in the pre-Hispanic area known as Acolhuacan, which today is the municipality of Texcoco, México state.

Cervantes said the discovery is “very important because not only can it provide us with information about something as basic as building systems . . . but it can also provide us with information about the kind of activities that were carried out here and about the political organization.”

He added that construction of the tecpan had been dated to the early 1400s, explaining that the hypothesis was primarily based on the type of ceramic artifacts found at the site.

The structure itself was built out of both volcanic and river rock joined together with mud. The archaeologists have found evidence that the tecpan was extended in later construction phases.

“It should be noted that the work done so far has only allowed us to excavate and record a section of the architecture from the most recent construction stage of the building. From the older period, only a stucco floor, that is perhaps from a room, and a section of wall . . . have been recorded,” Cervantes said.

The Atenco Omac tecpan appears on the so-called Uppsala map, which is stored in the library of the university in the Swedish city of the same name.

On that map — which was made in around 1550 and is considered one of the most important maps from early Spanish colonial days — a frontal view of the structure appears along with a jade frieze on its roof, which indicated that the tecpan located in Coyoacán was one of the most important of its time.

Cervantes said that its inclusion on the map is a sign that the Atenco Omac tecpan continued to be used for decades after the Spanish conquest in 1521.
