The Asklepieion of Pergamon

A short site biography

The Asklepieion of Pergamon, seen from the theater

Sanctuaries in the ancient world were at the crossroads of religious aspirations with social, economic and (geo)political motives, making them vibrant and interactive hotspots at several scales. The sanctuary of Asklepios was such a space for nearby Pergamon, for over 600 years. Developing from a natural shrine in a spring-fed basin to a place of healing, the Asklepieion gradually became a center of gravity, drawing travellers near and far, and attracting the attention of Hellenistic kings, the local elite, Roman emperors, as well as those seeking healing. By the imperial period, Asklepios had become Pergameus Deus, the principal god of the city. This story map gives the general story of the sanctuary.

Legendary beginnings

1

Pergamon

According to the travel writer Pausanias ( 2.26.8-9 ), the cult of Asklepios at Pergamon was founded by a man named Archias, son of Aristaichmos, from Pergamon, probably some time in the fourth century BC.  Pergamon is a UNESCO World Heritage site , and has been excavated by the German Archaeological Institute (DAI) for over a century. Find out more about the current project '  Transformation of the Pergamon Micro-region' here

The Pindasos mountains

While hunting in the nearby Pindasos mountains (today the Kozak range), west of Pergamon, Archias injured himself. Seeking healing, he travelled to the sanctuary of the healing god  Asklepios , at Epidauros, in Greece...

3

Asklepios

 Asklepios  was a hero, the son of Apollo and the mortal Koronis, from Thessaly. He was raised by his father Apollo, who gave him the gift of healing, and tutored by the wise centaur Cheiron, on Mt. Pelion. Asklepios is often accompanied by  Hygieia , represented as his wife or daughter.

The Asklepieion at Epidauros

In the classical era, the most famous sanctuary of Asklepios was at Epidauros. Pilgrims, like Archias from Pergamon, came from far and wide looking for healing. They would usually sleep in the abaton where Asklepios would give instructions in their dreams on what they should do to be healed. Out of thanks they would give a gift (a votive) to Asklepios... Here we see the temple, the tholos, and the abaton at Epidauros.  Epidauros is also a UNESCO World Heritage site, find out more about it here

The Asklepieion of Pergamon

Archias was very thankful for receiving healing from Asklepios. His gift to the god was to found a new place of worship for him near his hometown, Pergamon. This image shows the later phase of the sanctuary, with the theater near the temples and altars - and Pergamon rising over the site in the background.

The tale of Archias would have taken place in the 4th century BC. But there is another Archias too, as Riethmüller (2011) points out, who had an important role to play later on. A 2nd century BC inscription mentions Archias as father of Asklepiades, whose descendants were to fulfill the priesthood as a hereditary position ( IvP II 251 ). Another Archias from Pergamon (perhaps the same?) is mentioned in an early 2nd c BC inscription from the Asklepieion in Epidauros – this Archias was envoy (theorodokos) during the rule of Eumenes I ( IG IV² 1 60 ). In any case, the connections with Epidauros are clear. 

These were a few of the prominent figures that played a role in promoting the cult and developing the sanctuary into a prominent sacred center.


‘Five easy phases’

The excavators identified 18 different construction phases (Bauphasen) of the shrine, published in the first volume of the excavation reports (Altertümer von Pergamon XI, Vols. 1-5). Luckily they also clustered these into five main phases, making it easier to follow the development of the shrine. The imperial phase of the shrine is best known, but one of the aims of this project is to tease out the pre-imperial phases, i.e. the development of the sanctuary in the Hellenistic and early Roman era. Overshadowed by the exceptional architecture of the imperial period, these phases deserve more attention, in order to understand the human interaction and progression of the sanctuary into a major supraregional shrine, especially under the Attalid kings.

Plans like this one, published in the Altertümer von Pergamon XI, Vol. I, Taf. 84, compress some 600 years of construction history at the site, showing us all of the structures from the different building phases on the site at the same time.

To understand the temporal depth of the shrine, it helps to break it down into main phases. The excavators clustered the 18 different construction stages into 5 main phases...

Phase 1 (Bauphasen 1-3) c. 425-275 BC

Early finds of human occupation in the area date from prehistoric times, especially the Bronze Age. The cult only becomes more apparent in the later 5th century BC. Some early structures are located near the rocky outcrop, called the Felsbarre in the archaeological reports. Probably the cultic center, this had a rock-cut well at the northern end of the rocky elevation. The site may have begun as a cult for Apollo or the nymphs.

Phase 2 (Bauphasen 4-8) c.275-200 BC

The heart of the healing sanctuary, the incubation structure, appears in the second phase, around 275-240, and is expanded several times, remaining a central feature of the shrine. By the mid-3rd century BC, the sanctuary was extended to the east, with the 'Nordostbau' that may have had a gateway function.

The shrine was further embellished with two successive temples in the west, one of which, according to the sources, held a cult image of Asklepios sculpted by Phyromachos of Athens ( Polyb. 32.15.3-4 ).

Destruction marks the end of this period, perhaps brought on by Prusias of Bithynia, who 'plundered all the shrines' of Pergamon, carrying off the cult image by Phyromachos ( Diod. Sic. 31.35 ).

Phase 3 (Bauphasen 9-12) c.200-125 BC

In the early 2nd century BC, under royal sponsorship by the Attalid kings, the sanctuary was configured as an enclosed space, according to the formal characteristics of the time. The shrine was connected to Pergamon by a sacred road. The boundaries of the sanctuary would have been marked by the incubation area in the northwest, and stoa architecture to the east, south, and west, with the long stoa extending further to the west behind the temple.

Phase 4 (Bauphasen 13-15) c.125 BC-100 AD

The following period begins in the turbulent 1st century BC, with the  Mithridatic wars of the 80s BC  and the persecution of the Roman residents of Pergamon. Together, they fled to the shrine of Asklepios where they sought refuge, only to be slaughtered there by their neighbors ( Appian Mithr. 4.23 ). Small wonder that the shrine lost its status of asylia (inviolability) in this era, followed by a period of decline that appears to have set in.

After the Mithridatic wars, asylia was regained for the sanctuary, sometime mid-century ( IvP III 1 ).

Construction activity resumed in the later part of the 1st century AD, under the Roman emperor  Domitian , who visited the sanctuary.

New structures include a third temple in the southwest corner, and the sacred way connecting the shrine with Pergamon was covered with a vaulted structure.

Phase 5 (High Imperial period)

The final period is marked by the drastic transformation of the shrine, most of which is associated with the reign of the emperor Hadrian. The sacred way was reconfigured with a colonnaded street leading down to the new propylaia (gateway) and into the shrine, with a surface area now roughly four times larger than the previous temenos (precinct).

The western complex, with its altars, temples, and incubation area, remained the old cultic center. Yet the rest presented a very different picture. Characteristic of this period is the north stoa, with the theater, but also the dedicated structures along the east side, including the library (dedicated by Flavia Melitine), the propylaia (dedicated by A. Claudius Charax) and the temple of Zeus Asklepios (dedicated by L. Cuspius Pactumeius Rufinus), modelled after the Hadrian’s Pantheon in Rome. The cryptoporticus led to the rotunda in the southeast corner, added somewhat later.

A closer look - the online deep map

The overview above gives us a view of the sanctuary largely from an architectural standpoint.

But what happened at the shrine, what did people do?

The material culture and textual evidence at the shrine can help us understand how the sanctuary functioned and what it meant to different people. Much of this was published in the Altertümer von Pergamon XI. Vols. 1-5, and the Inschriften von Pergamon, Teil 3 (Altertümer von Pergamon VIII). Recording and georeferencing this data was central to the project  'Deep-mapping the Asklepieion of Pergamon' - see the website  for more information about the project and its goals.

An important outcome is  'The Asklepieion of Pergamon - an online deep map' - askperg.org , a website that makes the data (ceramics, clay, varia, coins, inscriptions, literary texts) available to the public. This section uses this deep map to take a closer look at the features in each phase from the Asklepieion, comparing the architectural data from the phases in a GIS environment with the finds from that phase as these are registered in the online deep map.


Phase 1 (Bauphasen 1-3) Prehistoric to 275 BC

Some of the earliest finds include prehistoric material, much of which dates from the Bronze Age. A concentration of this material was recovered during the excavation of the 'Olivenhain', the area west of the sanctuary, in the 1960's, but some were also found in the area of the incubation complex, and among the structures under the theater.

Finds include: several closed vessels, like bowls and deep dishes (ceramics); and some stone tools (varia).

Phase 2 (Bauphasen 4-8) - c. 275-200 BC

The second phase sees the earliest monumentalization of the site, including a Doric temple for Hygieia ( IvP III 158 ). Also a cluster of structures appear around the incubation area, including the small 'Mosaikbau' from Bauphase 5. A concentration of coins from the 3rd century BC was found here, most of these were from Pergamon, but some were from as far away as Macedonia and Babylon. Another concentration of coins was found in an oinochoe (wine jug), buried near the area of the later East stoa. Most of these were from various places in Asia Minor, many in the Seleukid Empire. Ceramics from this period are largely tablewares, indicating that a lot of feasting went on, perhaps related to the sacrifices, but also 'everyday' eating activities for those who may have been staying at the shrine. More ritual activities may be indicated by the many terracotta figures found in the central area of the shrine (the Festplatz). Activities taking place after dark are indicated by the oil lamps, several of which were found in the central sanctuary, but also in the olive grove to the west. The structures under the theater seem to be related to residential/production centers, but several terracottas were found here as well, along with lamps and other ceramics.

Phase 3 (Bauphasen 9-12) - c. 200-125 BC

The monumentalization of the site increases in the early 2nd century BC. The finds increase in quantity. A new type of ceramic begins to appear in large quantities: the mould-made bowl (previously called 'Megarian bowls'  - see an example here ); these were characteristic for the region in this era. More inscriptions appear in this era, indicating personal devotion and dedications to Asklepios, but also to other gods such as Demeter ( IvP III 130 ), by private individuals. A few honorific inscriptions also appear, such as the one for Athenaios, one of the Attalid princes ( IvP III 3 ), but also for a Pergamene citizen, who is honored by the Ionian League ( IvP III 4 ). These indicate a political profile of the shrine for Pergamon. An exceptional decree from this period concerns honors for the last Attalid, Attalos III, who was to receive a statue next to Asklepios in his temple - this inscription was found in Elaia, the main harbor town of Pergamon ( IvP I 246 , with a  translation on attalus.org ).

  • [terracottas]

Phase 4 (Bauphasen 13-15) - c. 125 BC - 100 AD

The period following the Attalid kings marks the beginning of Pergamon under Roman rule. Initially, not a lot changed at the sanctuary - new structures did not appear until the later 1st century BC. This may well be connected to the turbulent times of the 1st century BC. Yet while the architecture may point to a decline, the material and epigraphic records indicate continuing activity at the sanctuary, albeit in lower numbers. Terracottas are still being offered, while ceramics indicate feasting activities, although most of these were found in the area west of the shrine. Inscriptions point to ongoing private dedications at the shrine as well as honorific monuments. One important inscription is  IvP III 1 , mentioning the restoration of asylia at the shrine.

In the early imperial era more construction takes place, including the heroon along the sacred way. The track of the sacred way is covered by vaulting, a 'via tecta' that protected pilgrims from the weather as they approach the shrine. The shrine gains attraction during the first century AD, drawing the attention of the emperor Domitian.

Phase 4 stories


Phase 5 (High Imperial period)

The high imperial period, roughly the 2nd and 3rd centuries AD, represents without a doubt the most florescent period of the sanctuary, concerning not just the architectural monuments, but also the material culture, epigraphic record, and literary texts. Besides the many tales of Aelius Aristides, this is the era in which the sanctuary becomes a mirror of Rome and an intellectual center for the elite of Pergamon and its region. It becomes a podium for figures such as Julius Quadratus Bassus, a descendant of the Attalids of Pergamon who received a state burial in Pergamon, at the order of Hadrian ( IvP III 21 ). Yet it continues to be a major hub, attracting pilgrims from far and wide who come to seek healing at the shrine.

Stories

One very good means of communicating spatial narratives to a larger audience is through  ArcGIS Story Maps . The use of story maps began with the  support grant from the Geodienst in 2020 , with the assistance of Paul Haan (PH) and Annemarie Galetzka (AG) from the Geodienst. Alexandra Katevaini (AK) was able to take this to a new level, not only as a tool to communicate research, but also as an  educational tool  that students can use to tell spatial stories drawn from their own research. 'The Asklepieion of Pergamon - an online deep map' is also a story map, built by Peter Merx (PM ) and Bridgit Hebner (BH) (Geodienst)

Some of these are presented here, with more to follow!
