The main shrine of the Temple of Isis

As you might guess, I’m always on the lookout for articles about Isis. Recently, I came across a Master’s thesis that—while it didn’t tell me much new—did remind me of the charming Isis temple in Pompeii, which is the only Italian Isis temple left standing today. I had a chance to visit it, lo those many years ago now. So I thought I’d tell you a bit about Her temple there.

One thing we know about Pompeii is that, in a city of about 20,000, about 10% of the population considered themselves Isiacs. So about 2,000 Isiacs were in Pompeii at the time it was buried in volcanic ash. Assuming you didn’t have to get them all in the sanctuary at one time (the temple grounds are not huge), that would have worked pretty well. Out of a group of about 2,000 Pagans, how many of them would actually show up for the rituals at any given time? About as many as would fit in that modest temple…a hundred, maybe 200 at most.

But being buried in volcanic ash wasn’t the first blow suffered by that lovely temple. Pompeii had ALSO had a recent earthquake, in 62 CE, with the Vesuvial eruption following in 79 CE. The earthquake had rattled down a lot of Pompeiian structures. In fact, one of the reasons that the Isis Temple was so well preserved (it is considered the most well preserved building in Pompeii) was that it had been rebuilt following the earthquake…and not all the other public buildings had.

A wealthy Pompeiian, Numerius Popidius Ampliatus, had had the temple rebuilt in the name of his six-year-old son, Numerius Popidius Celsinus, so that Numerius Junior would have a free ride to the Senate. (Politics never change.) But what’s of interest to us is not the political machinations of Dad Numerius, but the fact that rebuilding the Isis temple would have conferred that much status. Clearly, Isis was popular; connections with Her and the support of Her religion were politically expedient.

The temple was located behind the city’s main theatre building, which emphasizes the close relationship between Isis and the God of the Theatre, Dionysos or Bacchus. Dionysos was identified with Osiris; and so, He was a natural partner for Isis. In fact, a sacred image of Dionysos, along with His requisite panther, was located in a special niche on the backside of the main Isis shrine.

On either side of the Dionysos image was a pair of large, stuccoed ears. The existence of these ears shows a direct connection between the Italian temple and Egyptian tradition. Egyptian temples often had God-sized ears carved on the back of the temple, just behind the innermost shrine. The common folk, who could not enter the holy of holies, could—by virtue of these Divine ears—speak directly to the Goddess or God of the temple. A hole drilled through the back of the temple, and a priest or priestess on the other side, served to transmit the concerns of the suppliant to the Deity. No doubt the same thing was intended in Pompeii.

This next photo is the main shrine, the naos and pronaos, of the Isis temple. The sacred images of Isis and Osiris would have stood here.

There was a mosaic floor in this area, which has now been lost. Lost where? I don’t know. Perhaps stolen from the site. On either side of the main entrance (the central opening you see here), were two niches, perhaps intended for images of Anubis and Harpocrates, to Whom two altars within the sanctuary were dedicated.

The small building where the sacred water for the Isis rites was kept

The low structure on the left is the main altar; the remains of a sacrificial fire and burnt offerings were found there.

Just to the left of the main altar is a small building where they kept the sacred water for purification. Likely, this would have been Nile water. Roman satirists mocked female Isis devotees for making pilgrimage to Egypt to bring back the sacred waters of the Nile. (We cannot be sure whether the satirists were more interested in mocking Isiacs or women by such statements, but either way, nice, huh?) The sacred water was kept in an underground chamber.

 You can see a little way into the building, which is about the size of one of those pre-fab garden sheds. The main altar is on the right, in front of the building.

The thing we can’t really imagine from any of these pictures is how the living temple would have looked. Paintings covered most all the walls; colorful mosaics decorated both walls and floors; shaven-headed priests and veiled priestesses moved to and fro in service to the Goddess. 

This one isn’t from Pompeii, but from Herculaneum; you can see that they were indeed trying to keep the “Egyptian” in temples of Egyptian Deities

Behind the main shrine, there was a large-ish room in which, I subsequently learned, the initiates of Isis met. I didn’t take a picture of it because the site really didn’t look like anything much. But that was because they took all the good stuff to the museum. The walls had been covered with images evocative of Egypt. Near the entrance, archeologists found a beautiful marble head of Isis. The body of the image was of wood and was dressed in garments of real fabric and would have been cared for on a daily basis by the temple personnel.

This is not that image. But it IS one of the statues rescued from the temple. I didn’t get to see it in person because the Naples Museum had that wing of the museum closed the day we were there. Dang. From what I’m reading, it looks like they may have made a replica and put it in place in the sanctuary. I hope so. Let me know if you’ve seen it.

At any rate, this is one of my favorite non-Egyptian Isis images, and I leave you with Her graceful Self:

Isis & Io

According to Herodotus, the Egyptians never sacrifice cows…

“…for these are sacred to Isis. For the image of Isis is always made in the form of a woman with the horns of an ox, as Io is pictured by the Greeks; and for that reason all Egyptians are alike in treating cows far more holy than other beasts.”

This painting is from the Temple of Isis in Pompeii and shows Isis receiving the “bull-maiden,” Io

Who is Io and how is she (or She?) connected to Isis?

The story of Io is a Greek myth and apparently an ancient one. Here’s the tale:

Io was a priestess of Hera, even the first priestess of Hera, having established the Goddess’ worship in Argos. Io is also a naiad or water nymph, daughter of the River God, Inakhos.

Theoi.com (a wonderful mythology website) tells us that Io, in the Argive dialect, means “moon.” Other scholars have speculated that Io was a Hellenized version of an Egyptian word for both moon and Moon God, Iah.

In the image above (you can click it to see it larger), from Pompeii’s Temple of Isis, we can see that the woman on the left does indeed have horns as in Herodotus’ description, although Isis, on the right with the cobra, does not. Judging by the details in this painting, it appears the Italian Isiacs were trying to maintain the Egyptian flavor of their rites. Note the diaphanous nature of Isis’ robe, as well as the breast-baring robe of the (probably) priestess behind Her, who holds a sistrum. Another figure, probably a priest, holds a sistrum, wand, and situla.

Zeus turning Io into the white cow; art by Leo & Diane Dillon

It seems more than likely that the artist was depicting the Isiac priestess and priest as he had seem them in the temple of Isis.

Anyway, back to our story. Hera’s ever-unfaithful husband, Zeus, falls in love with the lovely lunar nymph Io—either because of her great beauty or due to the spells of a iynx (a magical wheel sacred to Hekate; also known as Hekate’s Top or Wheel).

Io, meanwhile, had dreams that told her she should indeed surrender to Zeus, but when she told her father about them, he decided a second opinion was in order. Yet after consulting the Delphic oracle and the oracle of Dodona (an oracle of Zeus, by the way, so…), the answer remained the same. Thus, Io went secretly to Zeus and they made love. Now betrayed not only by Her husband but also by Her priestess, Hera was, to say the least, not pleased.

To protect Io from Hera’s anger, Zeus turned her into a beautiful white cow. Hera, pretending ignorance of the true identity of the lovely cow, promptly demanded that Zeus give the cow to Her. He could do nothing but comply. To guard Her new possession, Hera brought in Argos, Who had a hundred watchful eyes. Due to His many eyes, Argos was able to keep permanent vigil and was therefore a formidable guardian. But Zeus enlisted the aid of Hermes to help Io escape, which He finally did by killing Argos.

Io, wandering as a white cow by artist William Bottini

Io, still in the form of a cow, made good her escape, so Hera sent a horsefly or gadfly to torment her until she was driven mad. As a mad cow, she wandered and wandered across the world. In her wanderings, she gave her name to many geographic features. For instance, the Ionian Sea is supposed to be named for her. Finally, the white cow, Io, arrives in Egypt.

There she regained her human form—Aeschylus says Zeus healed her—and bore Zeus’ son, Epaphus. Herodotus gives Epaphus as an alternative name for the Egyptian Apis bull. (Some of you may remember that the Isis-cow is the one who gives birth to the Apis bull.)

Other stories have Io, already in human form, kidnapped by Phoenicians or pirates, and brought to Egypt. But Io’s troubles are not yet over, for Hera next ordered the Kouretes (young Divine warriors Who serve the Mother Goddess) to kidnap Epaphus—so once again, Io wandered, this time, searching for her lost son. At last, she learned that the queen of Byblos was raising Epaphus. Io went to Byblos and eventually returned with Epaphus to Egypt where, according to Apollodorus, Io “dedicated an image to Demeter, called Isis by the Aigyptians, as also they called Io herself.”

The Hesat or White Cow, identified with both Hathor and Isis

Despite a few Egyptian-ish details in Io’s tale, Io’s connection with Isis, or even identification with Her, may, at first, be a bit puzzling. Yet, there are a number of correspondences between Isis and Io. The theme of searching for a loved one, pursued by an enemy is common to both. In fact, both wander twice. Both appear as white cows. Both are associated with the moon. Both are aided by the God of Knowledge; Hermes in the case of Io, Thoth in the case of Isis. In Plutarch’s later version of the Isis-Osiris myth, Isis finds Osiris’ body in Byblos. Io finds her son in Byblos. And in Apuleius’ tale of initiation into Isis’ Mysteries, the theme of being returned to human form after suffering trials in the form of an animal applies to Lucius in Apuleius’ tale and to Io in Her many myths. A 10th century CE lexicon or encyclopedia, known as the Suda (or Suidas), makes the identification complete under the entry for Isis:

Isis: She is called Io. She was snatched by Zeus from Argos and he, fearing Hera, changed her first into a white cow, then into a black one, and then into a one that was violet-coloured. After wandering around with her, he came into Egypt. The Egyptians, then, honour Isis, and for this reason they carve the horns of a cow on the head of her statue, alluding to the change from maiden to cow.

It is always interesting to me that when we first see the connections drawn by the ancients between the Deities (for Io becomes a Goddess), we can, at first, find them to be something of a stretch.

Yet if we follow the trail a bit more, the associations become much less strained. Io is certainly a case in point. When we look deeper into the myths and stories, we find the holy correspondences. We see the sacred connections. We glimpse a little more of the Divine interweavings that underlie and interpenetrate all things.

NOTE: It turns out that Io was one of the most frequently cited identifications with Isis in Roman literature. In other words, they were understanding Isis through the story of Io. Some of the Roman poets, separated from their lovers by the Isiac requirement for sexual abstinence before specific rites, complained rather bitterly about said separations. And to tell the truth, they were kinda jerks about it.
