Phaistos Disc

The Phaistos Disc (also spelled Phaistos Disk, Phaestos Disc) is a disk of fired clay from the Minoan palace of Phaistos on the Greek island of Crete, possibly dating to the middle or late Minoan Bronze Age (2nd millennium BC). It is about 15 cm (5.9 in) in diameter and covered on both sides with a spiral of stamped symbols. Its purpose and meaning, and even its original geographical place of manufacture, remain disputed, making it one of the most famous mysteries of archaeology. This unique object is now on display at the archaeological museum of Heraklion.

The disc was discovered in 1908 by the Italian archaeologist Luigi Pernier in the Minoan palace-site of Phaistos, and features 241 tokens, comprising 45 unique signs, which were apparently made by pressing hieroglyphic "seals" into a disc of soft clay, in a clockwise sequence spiraling toward the disc's center.

The Phaistos Disc captured the imagination of amateur and professional archeologists, and many attempts have been made to decipher the code behind the disc's signs. While it is not clear that it is a script, most attempted decipherments assume that it is; most additionally assume a syllabary, others an alphabet or logography. Attempts at decipherment are generally thought to be unlikely to succeed unless more examples of the signs are found, as it is generally agreed that there is not enough context available for a meaningful analysis.

Although the Phaistos Disc is generally accepted as authentic by archaeologists, a few scholars believe that the disc is a forgery or a hoax.


The Phaistos Disc was discovered in the Minoan palace-site of Phaistos, near Hagia Triada, on the south coast of Crete; specifically the disc was found in the basement of room 8 in building 101 of a group of buildings to the northeast of the main palace. This grouping of 4 rooms also served as a formal entry into the palace complex. Italian archaeologist Luigi Pernier recovered this remarkably intact "dish", about 15 cm in diameter and uniformly slightly more than one centimetre in thickness, on 3 July 1908 during his excavation of the first Minoan palace.

It was found in the main cell of an underground "temple depository". These basement cells, only accessible from above, were neatly covered with a layer of fine plaster. Their content was poor in precious artifacts but rich in black earth and ashes, mixed with burnt bovine bones. In the northern part of the main cell, in the same black layer, a few inches south-east of the disc and about twenty inches above the floor, Linear A tablet PH 1 was also found. The site apparently collapsed as a result of an earthquake, possibly linked with the eruption of the Santorini volcano that affected large parts of the Mediterranean region during the mid second millennium BC.


The Phaistos Disc is generally accepted as authentic by archaeologists. The assumption of authenticity is based on the excavation records by Luigi Pernier. This assumption is supported by the later discovery of the Arkalochori Axe with similar but not identical glyphs.

The possibility that the disc is a 1908 forgery or hoax has been raised by two or three scholars. According to a report in The Times the date of manufacture has never been established by thermoluminescence. In his 2008 review, Robinson does not endorse the forgery arguments but argues that "a thermoluminescence test for the Phaistos Disc is imperative. It will either confirm that new finds are worth hunting for, or it will stop scholars from wasting their effort."

A gold signet ring from Knossos (the Mavro Spilio ring), found in 1926, contains a Linear A inscription developed in a field defined by a spiral—similar to the Phaistos Disc. This is considered as evidence that the Phaistos Disc is a genuine Minoan artifact.


Yves Duhoux (1977) dates the disc to between 1850 BC and 1600 BC (MMIII) on the basis of Luigi Pernier's report, which says that the Disc was in a Middle Minoan undisturbed context. Jeppesen (1963) dates it to after 1400 (LMII-III). Doubting the viability of Pernier's report, Louis Godart (1990) resigns himself to admitting that archaeologically, the disc may be dated to anywhere in Middle or Late Minoan times (MMI-LMIII, a period spanning most of the 2nd millennium BC). J. Best (in Achterberg et al. 2004) suggests a date in the first half of the 14th century BC (LMIIIA) based on his dating of tablet PH 1.


The inscription was apparently made by pressing pre-formed hieroglyphic "seals" into the soft clay, in a clockwise sequence spiraling towards the disc's center. It was then fired at high temperature. The unique character of the Phaistos Disc stems from the fact that the entire text was inscribed in this way, reproducing a body of text with reusable characters.

The German typesetter and linguist Herbert Brekle, in his article "The typographic principle" in the Gutenberg-Jahrbuch, argues that the Phaistos Disc is an early document of movable type printing, since it meets the essential criteria of typographic printing, that of type identity:

An early clear incidence for the realization of the typographic principle is the notorious Phaistos Disc (ca. 1800–1600 BC). If the disc is, as assumed, a textual representation, we are really dealing with a "printed" text, which fulfills all definitional criteria of the typographic principle. The spiral sequencing of the graphematical units, the fact that they are impressed in a clay disc (blind printing!) and not imprinted are merely possible technological variants of textual representation. The decisive factor is that the material "types" are proven to be repeatedly instantiated on the clay disc.

As a medieval example for the same technique he goes on to cite the Prüfening dedicatory inscription.

In his work on decipherment, Benjamin Schwartz also refers to the Phaistos Disc as "the first movable type".

In his popular science book Guns, Germs and Steel, Jared Diamond describes the disc as an example of a technological advancement that did not become widespread because it was made at the wrong time in history, and contrasts this with Gutenberg's printing press.
