The construction of the temple began at the beginning of the century BC. C. the Nubian king Adijalamani of Meroe, who built a chapel dedicated to the gods Amun and Isis. The chapel, decorated with reliefs, is one of the few places where this monarch is documented. Adikhalamani's other monuments are his Philé stele "Phile (Egypt)") (fragmented, and reused in the expansion of the temple of Isis by Ptolemy V Epiphanes) and his tomb at Meroe. Later, different kings of the Ptolemaic Dynasty built new rooms around the original core until it gave it an appearance close to its current one. After the annexation of Egypt by the Roman Empire, it was the emperors Augustus, Tiberius and, perhaps Hadrian, who completed the construction and decoration of the building. With the closure of the sanctuaries of Isis in Philé in the 2nd century, the temple ceased to be a place of pagan worship, and its progressive abandonment and deterioration began.
As already mentioned, King Ptolemy IV Philopator or more probably the Nubian king Adijalamani (Adikhalamani) of Meroe, ordered construction around the year 200 BC. C. a chapel in honor of the god Amun of Debod, in the town of Debod, southern Egypt (in the place where the remains of an ancient Ramesside cult building were located). This is the chapel known as the "chapel of the reliefs", or "chapel of Adijalamani", where inscriptions referring to Amun can be seen. Ritual scenes also appear in the reliefs of the chapel where it is said that "King Adijalamani orders the construction of the monument in honor of his father Amun" and that "Amun lives in Debod." The temple is closely linked to a historical event of extraordinary importance in the history of Ptolemaic Egypt: the so-called "Theban Secession". At this time, for twenty years (205-185 BC) all of Upper Egypt will be independent of the Alexandrian power; The Thebaid, as an independent state, will have its own kings. These internal dissensions in Egypt allow the Kushites to advance to Philé, occupying the entire Dodekaschoenos, which explains their presence in Philé itself, in Kalabsha, in Dakkah and in Debod.
Amun of Debod is going to be the main deity of the temple. Little by little Isis will displace him from this preeminent place, but certain indications make researchers think that, at the end of the Ptolemaic era, Amun of Debod will recover his role as the main deity of the temple.
Adijalamani will bring Nubian divinities to Debod (this is the case of Apedemak, the powerful Meroite dynastic lion god, who is mentioned on the lintel at the entrance to the Adijalamani Chapel – this block is today in the temple museum, that is, on its upper terrace). This is the northernmost known mention of this Meroitic lion god.
In the Ptolemaic era, the sanctuary was expanded with new rooms, following a traditional policy that left the previous building "invisible" (the initial architectural core), which was surrounded by the Ptolemaic additions, visible from the outside. Ptolemy VI Philometor, once the lágida dominion had been restored in Nubia, consecrated the temple of Debod to Isis. Ptolemy VIII Evérgetes dedicated a naos to Isis in the temple and perhaps added another room to the initial chapel. Ptolemy XII Auletes dedicated another naos (now lost) to the god Amun of Debod.
With the arrival of the Romans and the incorporation of Egypt into the Empire, new expansion works were carried out in the temple, dating back to the principalities of Augustus and Tiberius:.
• - Construction of a pronaos with a hypostyle façade (4 columns of floral order, two of the capitals unfinished) with access flanked by intercolumnial walls.
• - Reliefs on the outside in the aforementioned intercolumniations (Augustus before the gods Isis, Osiris, Amun of Debod and Maahes or Mahesa).
• - Complete decoration of the interior walls of the pronaos (or vestibule) hypostyle; Augustus would have started this decoration, which would be finished by Tiberius.
• - Construction of an annex building, attached to the temple, which has been considered a mammisi.
The Romans will bring new divinities to the temple, linked mostly to the theological order of Philé. In the vicinity of the temple, although outside the religious area and necropolis, there are authors who think that a small Roman garrison was installed, called - in the topography of the area - Parembole, but the truth is that no Roman military vestige has been found in the area, nor any graffiti in Latin on the temple to corroborate it.
It is likely that we owe some of the final architectural reforms of the Greco-Roman temple to the Antonine emperors. Beginning with the reign of Diocletian, the area suffered with special intensity from the attacks of nomads, in what appears to be a two-way Nubian Völkerwanderung: south-north and deserts-Nile. The Romans abandon the border of Maharraqa, which goes back to Philé. All Roman camps south of Philé are set up. Nubia, and therefore Debod, are at the mercy of the nomads Blemios, who leave their peculiar mark (both epigraphic and iconographic) on the walls of the sanctuary. When Emperor Theodosius I closes all the pagan temples of the Empire (with the exception of Philé), Debod is no longer sensu stricto under Roman orbit.
Later, Emperor Justinian (1st century AD) would decree the closure of the few pagan temples that were still functioning throughout the Byzantine Empire (of which Egypt was a province). With this decree, Egyptian temples dedicated to traditional gods were also closed. The Justinianic legal measure fundamentally affected two temples with a long tradition in Egypt: the oracle of Zeus-Ammon in Siwa and the temple of Isis in Philé. The Isiac cult in Philé was eliminated and its premises occupied by a Christian community that consecrated the temple to Saint Stephen. At that time the Christianization of Nubia began. In Debod there are traces of the Christian stage.
Debod will be visited during Late Antiquity, the Middle Ages and the Modern Age, by nomads, by pagan pilgrims (who leave proskynemata[4] on its walls) and by Christians; Finally, it will be a building occasionally occupied by Muslims. All these human groups will leave their mark on the ancient walls of the temple, as will later romantic travelers. The toponymy of the place will maintain the original, Egyptian name (ta-Hut), deformed into "Dabud", "Debod".
The first exact description of the building in Europe was made in 1813 by the Swiss explorer Johann Ludwig Burckhardt when he was traveling on a mission for the British African Association. Champollion himself visited Debod, leaving a brief reference to the building. Throughout the century, the temple was visited again by explorers and Egyptologists who offered a graphic description and indirectly showed in their work the gradual deterioration of the building. Here, as an example, is how the temple was described in the diary of a Russian traveler (Joseph Ssenkowsky, professor of oriental languages at the University of Saint Petersburg), in the spring of 1821: "In Wadi Debod there is a small temple of only 75 feet in length, in a very good state of preservation. In front of it are three moles, in a row, which once served as entrances through various walls that They must have surrounded the temple. Today, only the remains of the second of these walls are visible. This temple contains, in addition to the vestibule, only the central one is decorated with reliefs. It seems that it must have been dedicated to Isis. Its proximity to Philé convinces me that it is ancient Parembole, a place that was only 16,000 steps from Aswan.
When the first dam (known as the Aswan Low Dam) was built in that territory in 1907, the temple was greatly affected, as it remained underwater for about nine months a year. The almost constant flooding of the temple caused the loss of the polychrome and damage to some of its reliefs. The sandstone also suffered extensive wear. This erosion caused by the waters of the Nile was added to the damage caused by the earthquake of 1868. In view of this damage, the Egyptian Antiquities Service asked the Egyptian architect al-Barsanti to proceed with its restoration. After the completion of the work, the German Günther Roeder carried out an exhaustive study with photographic documentation, plan drawings, elevations and comments. His work remains the fundamental bibliographical reference of the building, a century later.
In 1961, due to the construction of the new Aswan Dam, the temple (and other buildings) was dismantled by a Polish archaeological mission (which located the oldest levels of the building, from the Ramesside period—Seti II—) and its stones were deposited on Elephantine Island until their later transfer to the port of Alexandria. From this port he made his final journey until he reached Spain, after a diplomatically complex transfer, full of lights and shadows, in which prestige, money, institutions and official organizations were at the core of a difficult and tough negotiation (in clear contradiction with the official statements that remain to this day) as Jambrina has shown (see bibliography).
In its new location, the Egyptian sanctuary was inaugurated on July 18, 1972 by Carlos Arias Navarro, mayor of Madrid.
