Biography

After receiving a PhD in Mathematical Physics at the University of Milan, Magli developed his academic career at the Politecnico of Milan, where he became full professor of Mathematical Physics in 2005. Since 2009, he has taught a course on archaeoastronomy, first ever such course offered in an Italian University.

Work

In the field of relativistic astrophysics, Magli has worked on the so-called Cosmic Censorship conjecture. He was the first to find the general exact solution of the Einstein field equations for spherically symmetric spacetimes with tangential stresses and, together with R. Giambo', F. Giannoni and P. Piccione, to investigate the nature of the final state for these gravitational collapse models. [1]

In the field of archaeoastronomy, Magli has investigated the foundations of the discipline and its relationship with "exact" sciences, insisting in particular on the possibility for Archaeoastronomy to make "predictions" - to be tested against facts - as any other scientific discipline can do. These ideas have been applied in particular to the relationship between topography, astronomy and dynastic history in the Egyptian pyramid's fields. In this context Magli proposed an inverse chronology between the two main pyramids of Giza as a consequence of the astronomical data, a theory which - thanks to Juan Belmonte of the IAC - developed in the idea, sustained today by both authors, that the project of the two was conceived together by Khufu in order to actualize his Akhet, symbolic horizon. [2] [3]

Using archaeoastronomy arguments, Magli proposed an explanation for the site of the Abusir pyramid's field, as well as a possible location where the missing pyramid of the 6th dynasty king Userkare might have been located. Magli has also investigated the meaning of the Inca citadel of Machu Picchu, proposing that it was a pilgrimage center conceived in pair with that of the Island of the Sun on the Titicaca Lake. [4]

Magli has also worked together with Robert Hannah [5] on the role of the sun in the original project of the Pantheon. [6] His researches have been frequently reported in press and media releases, [7] and have been the subjects of two CNN documentaries of the "Revealer" series. [8] [9] Magli is one of the co-authors to the thematic study "Heritage sites of astronomy and archaeoastronomy in the context of the Unesco World Heritage convention".

<span class="mw-page-title-main">Archaeoastronomy</span> Interdisciplinary study of astronomies in cultures

Archaeoastronomy is the interdisciplinary or multidisciplinary study of how people in the past "have understood the phenomena in the sky, how they used these phenomena and what role the sky played in their cultures". Clive Ruggles argues it is misleading to consider archaeoastronomy to be the study of ancient astronomy, as modern astronomy is a scientific discipline, while archaeoastronomy considers symbolically rich cultural interpretations of phenomena in the sky by other cultures. It is often twinned with ethnoastronomy, the anthropological study of skywatching in contemporary societies. Archaeoastronomy is also closely associated with historical astronomy, the use of historical records of heavenly events to answer astronomical problems and the history of astronomy, which uses written records to evaluate past astronomical practice.

The Great Pyramid of Giza is the largest Egyptian pyramid. It served as the tomb of pharaoh Khufu, who ruled during the Fourth Dynasty of the Old Kingdom. Built c. 2600 BC, over a period of about 27 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only wonder that has remained largely intact. It is the most famous monument of the Giza pyramid complex, which is part of the UNESCO World Heritage Site "Memphis and its Necropolis". It is situated at the northeastern end of the line of the three main pyramids at Giza.

Machu Picchu is a 15th-century Inca citadel located in the Eastern Cordillera of southern Peru on a 2,430-meter (7,970 ft) mountain ridge. Often referred to as the "Lost City of the Incas", it is the most familiar icon of the Inca Empire. It is located in the Machupicchu District within Urubamba Province above the Sacred Valley, which is 80 kilometers (50 mi) northwest of Cusco. The Urubamba River flows past it, cutting through the Cordillera and creating a canyon with a tropical mountain climate. In reference to the site's name, for most English or Spanish speakers, the first 'c' in Picchu is silent. In English, the name is pronounced MAH-choo PEE-choo or MATCH-oo PEAK-choo, in Spanish as or, and in Quechua as.

Saqqara, also spelled Sakkara or Saccara in English, is an Egyptian village in the markaz (county) of Badrashin in the Giza Governorate, that contains ancient burial grounds of Egyptian royalty, serving as the necropolis for the ancient Egyptian capital, Memphis. Saqqara contains numerous pyramids, including the Pyramid of Djoser, sometimes referred to as the Step Tomb, and a number of mastaba tombs. Located some 30 km (19 mi) south of modern-day Cairo, Saqqara covers an area of around 7 by 1.5 km.

The Great Sphinx of Giza is a limestone statue of a reclining sphinx, a mythical creature with the head of a human and the body of a lion. Facing directly from west to east, it stands on the Giza Plateau on the west bank of the Nile in Giza, Egypt. The face of the Sphinx appears to represent the pharaoh Khafre. The original shape of the Sphinx was cut from the bedrock, and has since been restored with layers of limestone blocks. It measures 73 m (240 ft) long from paw to tail, 20 m (66 ft) high from the base to the top of the head and 19 m (62 ft) wide at its rear haunches.

Spanning over three thousand years, ancient Egypt was not one stable civilization but in constant change and upheaval, commonly split into periods by historians. Likewise, ancient Egyptian architecture is not one style, but a set of styles differing over time but with some commonalities.

The Djedi Project was an exploration of the interior of the Great Pyramid of Giza. The project team was made up of international and Egyptian experts. The name derived from Djedi, the ancient Egyptian magician consulted by Pharaoh Khufu when planning his famous pyramid. As Dr. Zahi Hawass announced on his blog: "The purpose of this project is to send a robotic tunnel explorer into the two "air shafts" that lead from the Queen's Chamber of the Great Pyramid of Khufu to gather evidence to determine the purpose of the shafts."

<span class="mw-page-title-main">Ancient Egyptian royal ships</span> Ancient Egyptian buried ships

Several ancient Egyptian solar ships and boat pits were found in many ancient Egyptian sites. The most famous is the Khufu ship, which is now preserved in the Grand Egyptian Museum. The full-sized ships or boats were buried near ancient Egyptian pyramids or temples at many sites. The history and function of the ships are not precisely known. They are most commonly created as a "solar barge", a ritual vessel to carry the resurrected king with the sun god Ra across the heavens. This is a common theme in the Pyramid Texts, and these buried boats might be a real-life equivalent of solar barges. Similarly, another explanation behind these boats is that they were built for past kings to carry them to the afterlife. Because of these ships' association with the sun, they are often found in an east-west orientation in order to follow the path of the sun.

The Diary of Merer is the name for papyrus logbooks written over 4,500 years ago by Merer, a middle-ranking official with the title inspector. They are the oldest known papyri with text, dating to the 27th year of the reign of pharaoh Khufu during the 4th dynasty. The text, written with (hieratic) hieroglyphs, mostly consists of lists of the daily activities of Merer and his crew. The best preserved sections document the transportation of white limestone blocks from the Tura quarries to Giza by boat.
