When the sanctuary was uncovered in **1764**, an extraordinary amount of its decoration, sculpture and ritual furnishings still survived. The discovery immediately attracted enormous interest among scholars, artists and travellers and contributed decisively to the international fame of the Pompeii excavations. The complex visible in AD 79 had been almost entirely rebuilt after the major **earthquake of AD 62**, although the cult of Isis had been present in the city for much longer. ### Isis and her cult **Isis** was one of the principal deities of ancient Egypt. According to myth, she was both the wife and sister of **Osiris**. After Osiris was killed and dismembered by his brother Seth, Isis searched for and reassembled his body, restoring him to life through her magical powers. The story gave rise to some of the goddess’s most important associations: **protection, rebirth, salvation, fertility and hope for life after death**. During the Hellenistic period, her cult gradually spread beyond Egypt and throughout the Mediterranean. It also reached Italy and Campania, important crossroads in trade with the eastern Mediterranean. The cult of Isis found especially fertile ground in Pompeii and survived the profound political changes that followed the Roman conquest. ### A cult from Egypt The cult of Isis differed greatly from traditional public cults dedicated to deities such as Jupiter or Apollo. It was closely associated with **rites of initiation**, daily ceremonies, purification and the promise of special divine protection for worshippers. Egyptian culture also exerted a powerful fascination on Roman society. In the Pompeian sanctuary, its origins were continually evoked through images of Egyptian deities, Nile landscapes, crocodiles, sacred snakes, priests and ritual instruments. Entering the Temple of Isis therefore meant entering a space that symbolically conjured up a distant and mysterious world. ### The sanctuary High walls separated the complex from the surrounding streets. Beyond the entrance lay a **large porticoed courtyard**, with the temple dedicated to the goddess at its centre. The sacred building stood on a **high podium** and was reached by a frontal staircase. Columns supported the pronaos, which led into the **cella**, the temple’s most sacred room, where divine images and objects used in worship were kept. The layout of the complex allowed worshippers to move around the temple and take part in ceremonies held in the courtyard. ### The altar The **main altar** stood in front of the temple and was used for sacrifices and offerings. As in other ancient cults, the principal ceremonies did not necessarily take place inside the cella. Sacrifice normally occurred in the open air before the temple, where priests and worshippers could participate in the rite. Beside the altar was a structure used to dispose of or deposit the remains of ritual offerings. The courtyard was therefore the true centre of religious activity in the sanctuary. ### The purgatorium and sacred water One of the Temple of Isis’s most distinctive elements is the small building in the south-eastern corner of the courtyard, known as the **purgatorium**. It resembles a small temple and is decorated with refined stucco reliefs. Inside, stairs led down to an underground basin containing water used in **purification ceremonies**. Within the religious tradition, this water was symbolically understood to come from the **Nile**, the sacred river of Egypt. The water used in Pompeii did not, of course, actually come from Egypt; what mattered was the ritual meaning assigned to it. Nile water represented fertility, regeneration and life, all fundamental ideas in the cult of Isis. ### Rebuilding after the earthquake The earthquake of **AD 62** severely damaged the sanctuary. An important inscription found above the entrance records its reconstruction. According to the text, **Numerius Popidius Celsinus** rebuilt the Temple of Isis, which had collapsed in the earthquake, from its foundations at his own expense. The inscription adds a surprising detail: Celsinus was only **six years old**. In recognition of his generosity, the decurions admitted him to the civic order without charge. A six-year-old child could not, of course, have personally organised and financed a project on this scale. Behind it stood his family, connected with **Numerius Popidius Ampliatus**, a wealthy freedman. Attributing the work to the young Celsinus was probably also a means of advancing his future admission to the city’s political elite. ### Religion and social mobility The story of the Popidii family makes the Temple of Isis especially revealing from a social perspective. In the Roman world, a **freedman**—a formerly enslaved person who had gained freedom—could accumulate great wealth, but still faced significant restrictions on access to the highest public offices. His freeborn children, however, could aspire to a much higher social position. Financing the reconstruction of an important sanctuary allowed the family to display its wealth, devotion and generosity towards the community. The temple thus bears witness not only to religious life, but also to **social mobility in 1st-century AD Pompeii**. ### The ekklesiasterion Behind the temple was a large room known as the **ekklesiasterion**. It was probably used for meetings of the Isiac community and for ceremonies reserved for worshippers. The walls were richly painted with subjects connected with Egypt and the myth of Isis. One of the best-known images from this room depicts the **arrival of Io in Egypt**. In Greek myth, Io—loved by Zeus and transformed into a heifer—reached Egypt after a long journey, regained human form and became associated with Isis herself. In the Pompeian painting, Io is received by the goddess in a landscape populated by Egyptian figures and symbols. The original fresco is now in the **National Archaeological Museum of Naples**. ### The sacrarium Another particularly important room was the **sacrarium**. Some of the sacred objects used during ceremonies were probably kept here. Its walls had decoration strongly inspired by Egypt. Snakes, ritual baskets, lunar symbols and other motifs continually reminded worshippers of the cult’s distinctive character. These rooms show that the Iseum was not simply an ordinary Roman temple dedicated to a foreign deity. The entire building was designed to create a coherent religious world in which architecture, painting and ritual constantly evoked Egypt. ### Priests and initiates The sanctuary required **priests and personnel serving the cult**. The complex also included small rooms that may have been used by people working in the temple. The priests performed daily rites, cared for sacred objects and led ceremonies. Purification practices played an especially important role. Before taking part in ceremonies, worshippers had to prepare ritually through actions and forms of conduct that distinguished the cult of Isis from simpler forms of Roman civic religion. ### Music and ritual Music played an important part in ceremonies dedicated to Isis. One of the cult’s most characteristic instruments was the **sistrum**, a metal frame crossed by movable rods that produced a rhythmic sound when shaken. The sistrum frequently appears in images of Isis and her priests. Music could be accompanied by singing, prayers, perfumes and processions. The sanctuary must therefore have offered an experience very different from that suggested by its silent ruins today. During a ceremony, the courtyard might be filled with sound, incense, ritual water, priests and worshippers. ### The paintings When the Temple of Isis was discovered, much of its **painted decoration still survived**. The walls of the portico carried an extensive figurative programme. It included painted architecture, landscapes, still lifes, divine figures and scenes connected with Egypt. Colour and imagery transformed the courtyard into a far richer space than the one visible today. Many paintings were detached during the Bourbon excavations and transferred to Naples. Much of the original decoration can consequently now be seen in the **National Archaeological Museum of Naples**, where the relative arrangement of many paintings has also been reconstructed. ### Sculpture and furnishings Numerous **statues, small bronzes, ritual objects and furnishings** came from the sanctuary. The images represented Isis and other deities associated with the Egyptian and Graeco-Roman pantheons. Figures connected with the cult included **Osiris, Harpocrates and Anubis**. These objects were not merely decorative. They formed part of the sanctuary’s religious experience and helped create a space unmistakably associated with Egypt. Many of these objects are also now in the National Archaeological Museum of Naples. ### An exceptionally well-preserved sanctuary When excavators reached the Iseum in **1764**, they encountered an exceptional situation. Unlike many buildings that had been stripped of their most valuable decoration in antiquity, the sanctuary still retained much of its original assemblage. The temple, altars, paintings, statues and ritual objects made it possible to reconstruct a Roman place of worship with remarkable precision. It was the **first religious building in Pompeii to be uncovered in such a complete state**. The discovery made an immediate and enormous impression on 18th-century Europe. ### Pompeii and Egypt in the European imagination The Temple of Isis contributed greatly to Europe’s fascination with ancient Egypt. Artists, architects and travellers visited the sanctuary and reproduced its paintings and structures in engravings and drawings. Its discovery came many decades before Napoleon’s celebrated expedition to Egypt and therefore helped spread Egyptian imagery from the second half of the 18th century onwards. One of its most famous visitors was **Wolfgang Amadeus Mozart**, who came to Pompeii in **1770** with his father Leopold. Mozart was only fourteen years old. His visit to the Temple of Isis is often mentioned in connection with the Egyptian and initiatory atmosphere that, more than twenty years later, would characterise his opera ***The Magic Flute***. A direct relationship between the visit and the composition cannot be demonstrated, but the episode illustrates the powerful impression the sanctuary made on contemporary travellers. ### The discovery of 1764 Excavation began in **1764**, and the sanctuary was uncovered relatively quickly. The extraordinary quantity of material found prompted the Bourbon excavators to record the decoration carefully before transferring many elements to Naples. The drawings, engravings and measured records made during those years are now fundamental sources for reconstructing the complex’s original appearance. Further archaeological investigations took place in **1958–1959** and between **1988 and 1991**, providing a better understanding of the phases that preceded the 1st-century AD reconstruction. ### The Temple of Isis and the theatre district The sanctuary stands in one of the city’s most important cultural areas. Very close by are the **Large Theatre, Odeion, Triangular Forum, Samnite Palaestra and Temple of Asclepius, formerly known as the Temple of Jupiter Meilichios**. This concentration of buildings made Regio VIII a district in which religion, performance and cultural life were closely connected. Those attending a theatrical performance therefore passed places of worship that differed greatly from one another: very ancient Italic and Greek sanctuaries existed beside the Egyptian cult of Isis. It is among the clearest examples of the **remarkable religious diversity of Roman Pompeii**. ### A unique place for understanding religion in Pompeii The **Temple of Isis at VIII.7.28** is one of the monuments that best demonstrate how open Pompeian society was to influences from across the Mediterranean. A deity originating in ancient Egypt could be worshipped in the heart of a Roman city in Campania through rituals that combined Egyptian, Greek and Roman traditions. At the same time, the story of Numerius Popidius Celsinus shows how deeply religion, wealth and social ambition could be intertwined. Because of its exceptional state of preservation when discovered, the richness of its paintings and furnishings, and its importance in 18th-century European culture, the **Temple of Isis is one of the most significant and compelling monuments in ancient Pompeii**. ### Further information [Pompeii in Pictures](http://www.pompeiiinpictures.com/pompeiiinpictures/R8/8%2007%2028%20p5.htm) Detailed images of the building ### Video ### Map ![map](http://www.pompeiiinpictures.com/pompeiiinpictures/R8/8%2007%2028%20plan%202.jpg "map") - [ ![Click to enlarge image pompei_tempio_di _iside.jpg](https://www.pompeionline.net/plugins/content/jw_sig/jw_sig/includes/images/transparent.gif "Click to enlarge image pompei_tempio_di _iside.jpg") ](https://www.pompeionline.net/images/stories/Tempio%20di%20Iside/pompei_tempio_di%20_iside.jpg "You are viewing the image with filename pompei_tempio_di _iside.jpg") - [ ![Click to enlarge image pompei_tempio_di _iside_02.jpg](https://www.pompeionline.net/plugins/content/jw_sig/jw_sig/includes/images/transparent.gif "Click to enlarge image pompei_tempio_di _iside_02.jpg") ](https://www.pompeionline.net/images/stories/Tempio%20di%20Iside/pompei_tempio_di%20_iside_02.jpg "You are viewing the image with filename pompei_tempio_di _iside_02.jpg") - [ ![Click to enlarge image pompei_tempio_di _iside_03.jpg](https://www.pompeionline.net/plugins/content/jw_sig/jw_sig/includes/images/transparent.gif "Click to enlarge image pompei_tempio_di _iside_03.jpg") ](https://www.pompeionline.net/images/stories/Tempio%20di%20Iside/pompei_tempio_di%20_iside_03.jpg "You are viewing the image with filename pompei_tempio_di _iside_03.jpg") - [ ![Click to enlarge image pompei_tempio_di _iside_04.jpg](https://www.pompeionline.net/plugins/content/jw_sig/jw_sig/includes/images/transparent.gif "Click to enlarge image pompei_tempio_di _iside_04.jpg") ](https://www.pompeionline.net/images/stories/Tempio%20di%20Iside/pompei_tempio_di%20_iside_04.jpg "You are viewing the image with filename pompei_tempio_di _iside_04.jpg") - [ ![Click to enlarge image pompei_tempio_di _iside_05.jpg](https://www.pompeionline.net/plugins/content/jw_sig/jw_sig/includes/images/transparent.gif "Click to enlarge image pompei_tempio_di _iside_05.jpg") ](https://www.pompeionline.net/images/stories/Tempio%20di%20Iside/pompei_tempio_di%20_iside_05.jpg "You are viewing the image with filename pompei_tempio_di _iside_05.jpg") - [ ![Click to enlarge image pompei_tempio_di _iside_06.jpg](https://www.pompeionline.net/plugins/content/jw_sig/jw_sig/includes/images/transparent.gif "Click to enlarge image pompei_tempio_di _iside_06.jpg") ](https://www.pompeionline.net/images/stories/Tempio%20di%20Iside/pompei_tempio_di%20_iside_06.jpg "You are viewing the image with filename pompei_tempio_di _iside_06.jpg") - [ ![Click to enlarge image pompei_tempio_di _iside_07.jpg](https://www.pompeionline.net/plugins/content/jw_sig/jw_sig/includes/images/transparent.gif "Click to enlarge image pompei_tempio_di _iside_07.jpg") ](https://www.pompeionline.net/images/stories/Tempio%20di%20Iside/pompei_tempio_di%20_iside_07.jpg "You are viewing the image with filename pompei_tempio_di _iside_07.jpg") - [ ![Click to enlarge image pompei_tempio_di _iside_08.jpg](https://www.pompeionline.net/plugins/content/jw_sig/jw_sig/includes/images/transparent.gif "Click to enlarge image pompei_tempio_di _iside_08.jpg") ](https://www.pompeionline.net/images/stories/Tempio%20di%20Iside/pompei_tempio_di%20_iside_08.jpg "You are viewing the image with filename pompei_tempio_di _iside_08.jpg") - '+ ' ';
