Have you ever heard of the Mensa Isiaca?

Did this mysterious Isiac artifact serve as the altar when Plato received his initiation into the Egyptian Greater Mysteries in a secret, subterranean hall beneath the Great Pyramid? Was it an altar top from a Roman Temple of Isis? Was it a repository of ancient occult lore? A key to the hieroglyphs? Or the tarot? Perhaps it was just a rather expensive piece of home decor for a rich Roman with a penchant for Isis?

All of these things have been suggested as the ultimate identity of this significant Isiac artifact. It has quite the history…and some legit mysteries, all of which we take a look at as we try to find out more about this literally unique artifact—and discover what it has meant in the long story of the worship of our Goddess Isis.

As you may have guessed, “Mensa Isiaca” is Latin. It means “Table (or Tablet) of Isis.” It’s also known as the Bembine Table of Isis. I’ll explain why in a bit.

First, what is it?

The Mensa Isiaca is a large bronze tabletop inlaid with polychrome metals—that is, a variety of colored metals—featuring Egyptian figures in a selection of typical Egyptian-style poses, all surrounding the central, enshrined figure of Isis. Or at least She has always been taken to be Isis due to the popularity of the Goddess during the period of the Mensa’s creation, sometime between the 1st century BCE and the 1st century CE. And it was almost certainly made in Rome.

The reason we cannot be absolutely sure the central figure is Isis is that, while the Mensa includes hieroglyphs, they are only pseudo-hieroglyphs and cannot be read. They are decoratively placed near the figures, as well as around the lip of the Mensa and the borders that separate its three surface registers. So, unfortunately, they cannot help us clearly identify the figures on the Mensa. The Mensa’s later interpreters, however, did not know this and spent a good deal of brainpower on trying, unsuccessfully, to decipher the glyphs.

The art style is all very Egyptian, in the Hellenistic mode. In other words, the images look very much like the ones found in many of the Hellenistic-era temples we see in Egypt today. It’s that slightly softer style you see at Denderah rather than the older, crisper style at Abydos.

But before we go further, you may be wondering what the Mensa Isiaca looks like; click for a larger image:

I hadn’t remembered how large the Mensa Isiaca was until I read a recent article with results from an intensive study of the Mensa while it was on loan from Italy’s Turin Egyptian Museum to the Getty Museum in L.A. At almost 50 inches wide (126 cm) and 30 inches tall (75.5 cm), it is decidedly table-sized rather than tablet-sized. It also has a slightly-over-2-inch lip on all sides of the table. I had been picturing it as something a bit more portable. But no. It’s of an impressive size as well as being an impressive work of art.

While at the Getty Museum, researchers took advantage of new technologies that enabled them to study the Mensa Isiaca in new depth and non-invasively.

A striking feature of the Mensa is its polychrome inlays. Earlier in the Mensa’s history, some of the more colorful inlays had been described as enamel. Others suggested that the beautiful variety of colored metals were the result of Egyptian alchemical experiments. Researchers found that the metalsmiths used at least seven distinct alloys, including silver, gold, black bronze, and a variety of different copper and zinc alloys. They achieved colors from red, yellow, orange, and brown to blue-grey. Each figure is intricately outlined in silver or black bronze wire. The Mensa is in remarkably good shape and shows no signs of ever having been buried. In other words, it has remained in someone’s hands throughout its lifetime.

Polychrome metalwork was a specialty of Egyptian craftspeople; we have examples from at least the 18th dynasty and researchers now think the technique was much more widespread than they had previously believed. Thus, the Mensa Isiaca was created using techniques that were genuinely Egyptian—even if the craftspeople didn’t know hieroglyphs (many didn’t by that time). Due to the excellence of the work and Egyptian mastery of those techniques, my guess is that is was created by Egyptian metalsmiths working in Rome, perhaps with Roman smiths. But we have no proof. It could also have been made by Roman smiths in an Egyptianizing style.

What is its history?

There is no historical mention of the Mensa Isiaca until after the sacking of Rome in 1527. Some of the unpaid-for-a-long-time forces of the Holy Roman Emperor, Charles V, overran the city of Rome and went on a rampage of destruction, looting, and killing.

The Mensa was likely kept in one of Rome’s palaces prior to the sacking. Afterwards, it came into the hands of a blacksmith or ironworker who eventually sold it to Cardinal Bembo—after which it was known as the Bembine Table (or Tablet) of Isis. Bembo was an Italian scholar, trained in Neoplatonism and intensely interested in his country’s history. In later life, he was made a cardinal in secret. He is buried in the Santa Maria Sopra Minerva basilica, part of which lies over the older Temple of Isis in the Campus Martius.

The Mensa remained in Bembo’s hands until after his death. Then, it came into the possession of the Dukes of Mantua, who kept it in their museum until 1630, when Mantua was besieged and also sacked. We don’t know how, but it next came into the hands of Cardinal Pava, who gifted it to the Duke of Savoy, who eventually gave it to the King of Sardinia in 1730. In 1797, French troops brought it to Paris, where it was exhibited in the Bibliothèque Nationale. With peace between France and Italy, it was returned to Turin. Today, Turin is the site of Italy’s Museo Egizio (Egyptian Museum) and the permanent home of the Mensa Isiaca.

In Westcott’s book about the Mensa (see the image above), he notes that a guidebook for travelers to northern Italy by John Murray, published in 1863, mentions the Mensa and gives an unattributed history. Murray says that the Mensa was originally found on Mount Aventine in Rome where once stood a temple of Isis and suggests it was made during the reign of Emperor Hadrian. This period for its creation is entirely possible since Hadrian’s reign roughly matches the current scholarly dating for the Mensa Isiaca—and Hadrian himself was quite the Egyptophile. As far as I can tell, none of the known Isis temples in Rome was on the Aventine hill. But then, much of the Aventine is unexcavated since it is covered with many homes.

What is the Mensa Isiaca’s occult significance?

That’s enough of historical history (as far as we know it) for now. Its occult history is much more interesting. The Mensa Isiaca has been an inspiration to occultists for centuries and was believed to contain the deep secrets of ancient Egyptian mysteries and magic. We’ll get into that fascinating subject next time in Part 2.
