'Shattered Expectations: Archaeologists Uncover Ancient Egypt's First Astronomical Observatory'

Archaeologists have recognized the initial ancient Egyptian The astronomical observatory mentioned is reported to be the "first and largest" of its kind based on a translation, as stated by them. statement from the nation's Department of Tourism and Antiquities.

A group of Egyptian archaeologists unearthed remnants of a structure dating back to the sixth century B.C. three years prior while digging at an excavation site within the ancient city of Buto, known today as Tell Al-Faraein, located in Egypt’s Kafr El-Sheikh governorate.

"As we uncovered more, everything surpassed what we had anticipated," said Hossam Ghonim, the director general of Kafr El-Sheikh Antiquities and leader of the Egyptian archaeological team, during an interview with Live Science.

The team discovered the remains of an L-shaped structure made from mud bricks covering more than 9,150 square feet (850 square meters). This edifice features an eastern entryway highlighted by a classic gateway called a pylon. According to Ghonim, this portal opens up to an area where sunlight exposed the position where the sky watcher—referred to as 'smn pe,' typically a clergy member—stood for monitoring celestial bodies like the sun and stars.

The structure features an engraving of Smn Pe oriented towards the sunrise. According to Ghonim, this image represents the ancient Egyptians' link to the universe.

Initially, the team believed they had found a temple. However, as excavations continued, they unearthed artifacts and inscribed symbols like Chen, Cenet, and Benu, which were associated with time and astronomy, according to Ghonim. It was ultimately the uncovering of a massive sundial, alongside numerous inscriptions, additional artifacts, and the overall design of the edifice, that prompted researchers to declare their revised finding: This structure was actually an astronomical observatory, Ghonim elaborated.

As we explored along the north wall of the corridor, we uncovered a tilted stone sundial—a solar shadow instrument that gauged times like sunrise, noon, and sunset through changes in the sun’s cast shadows—an elegant but fundamental technique,” explained Ghonim, adding that researchers originally mistook this for a temple entrance. Additionally, the group unearthed an old Egyptian timing tool called a 'merkhet,' dating back to the sixth century B.C., at the location.

These discoveries illuminate the astronomical techniques Used by ancient Egyptians for determining the solar calendar and marking the dates of religious ceremonies like royal crowning events and agricultural cycles, as stated.

Mats and pillars

Within the hall, the archaeologists discovered a carved stone illustrating celestial perspectives of sunrises and sunsets over three different seasons.

Ghonim mentioned, "The ancient Egyptians saw the Earth and sky as two mats." They depicted the sky on what they called the 'Themet Hrt'—the sky mat—and the 'Themet Ghrt', which represents the Earth mat. It was used for their calendar, noting significant occurrences such as the Nile flood and harvesting seasons. This discovery marks the first known carved stone representation of this sort.

These discoveries, along with additional inscriptions, contribute to the proof of the ancient Egyptians' profound comprehension of seasonal shifts and fluctuations in daylight duration.

The archaeologists discovered a "trio of columns" near the entryway of the chamber—a peculiar arrangement since ancient Egyptian structures generally place columns at the far end of such spaces. The unconventional positioning of these columns implies that this edifice may not be a temple, contrary to earlier beliefs. "Our hypothesis was that these columns could symbolize the Egyptians’ threefold partitioning of time into years, months, and days," explained Ghonim.

In contrast to conventional monuments that usually feature just one pylon, this observatory was equipped with two pylons positioned opposite each other. These pylons encircled the round observation area and were meant to represent akhet , or the point where the sun emerges. In front of this Akhet stood a limestone watchtower that was probably originally part of a pair and utilized for observing stars, according to Ghonim.

The dig also revealed a statue featuring the falcon-headed deity Horus. As stated, the representation of Horus alongside his Eye symbolizes cosmic order and connects to celestial bodies like the sun and moon, as well as deities such as Horus himself and Wadjet—the chief gods of Buto.

In earlier days, Buto was consecrated to the deity Wadjet , a serpent deity renowned for safeguarding the king. Analyzing the observatory offers additional proof that Wadjet held significant importance. Buto , Ghonim said.

Within the observatory, the archaeologists discovered a gray granite statue. King Psamtik I from the Saite period — which marks the 26th dynasty — along with a bronze figurine of Osiris A deity linked to the underworld and resurrection is depicted alongside a serpent, which refers to the goddess Wadjet. According to Ghonim, these relics, together with several ceramic pieces utilized in religious ceremonies, help date the observatory back to the sixth century B.C., highlighting its combined purpose as both an academic research center and a site for spiritual activities.
