In 1908, Luigi Pernier found Crete’s Phaistos Disc with 241 stamped signs. 118 years later, its 45-symbol script remains undeciphered despite more than a century of study

Ancient artefacts can offer rare glimpses into societies that existed thousands of years ago, but some discoveries leave more questions than answers. The Phaistos Disc is one of the most popular examples. Connected with the Minoan civilization, the clay disc has attracted sustained attention because of its unusual symbols, spiral inscription and uncertain meaning.

Luigi Pernier discovered the Phaistos Disc in 1908

Italian archaeologist Luigi Pernier found the Phaistos Disc on July 3, 1908, at the palatial site of Phaistos on Crete. The discovery happened during fieldwork conducted by the Italian Archaeological Mission under Pernier’s direction.

The situations were unusual. Rather than being recovered in regular excavations, the disc was found during an evening inspection by the local foreman. It lay in Room 101 of the North-Eastern Complex, close to the Palace proper. The layer containing the object was a destruction level, although it had been disturbed during Hellenistic times.


The Phaistos Disc is a clay object measuring 16 centimeters in diameter. It was apparently intentionally fired and carries an inscription impressed on both sides. The signs follow a spiral arrangement, while small vertical lines divide the inscription into fields containing groups of symbols.

The two sides contain 241 signs in total, as per the details surrounding its discovery, while the inscription produced with 45 different stamps, which were likely made of metal.

What do the symbols on the disc represent?

The impressed images include subjects linked with the natural world and material culture. People, birds, plants and ships are among the motifs represented on the disc.

The signs are arranged into groups, with incised vertical or radiating lines separating them. The groups are generally regarded to represent words, while scholars generally agree that the individual signs are syllabograms that should be read along the incised spiral.

However, the actual contents remain unclear. Experts have not reached a definitive conclusion about the message or regarding its possible relationship to Linear A, Cretan Hieroglyphic and Linear B, the three pre-alphabetic scripts linked with the prehistoric Aegean.

Archaeological research has clarified its context

More latest fieldwork has helped researchers better understand the circumstances surrounding the disc. Work conducted by Pietro Militello in 2013 and 2015 clarified the archaeological context in which the object was found.

The pottery connected with the context was largely dated to one of the earliest phases of the Neopalatial period, the beginning of Middle Minoan IIIA. This was the period linked with the famous palace of Knossos and with Linear A and the earlier Cretan Hieroglyphic writing system, both of which remain undeciphered.

Evidence supports the disc’s authenticity

Recent research has offered evidence that the Phaistos Disc was not entirely isolated within Minoan culture. Studies of Protopalatial clay objects from Phaistos, mainly relief potmarks and impressed fine ware, have found similarities with signs discovered on the disc.

Relief potmarks happen on semi-coarse vessels from Phaistos, Hagia Triada and Kommos in the Western Mesara Plain, as well as at Malia. These marks are linked with the Protopalatial era, during the 19th and 18th centuries BCE, and have elaborate relief motifs on the external bases of vessels. They likely identified the craftsmen or workshops responsible for making them.

One Phaistian vessel carrying such a mark is a handled bowl found in 1965 at the Casa a Sud della Rampa. Its mark features a motif that is basically identical to sign No. 21 on the Phaistos Disc, the “comb sign.” A closely related sign was also discovered as an impression on a sealing recovered in 1955 from a deposit of administrative documents beneath Room 25 of the Second Palace of Phaistos.

Impressed pottery offers another clue

Another line of evidence arrives from research by Alessandro Sanavia into Phaistian impressed fine ware. This type of pottery is characteristic of the Protopalatial period and is found particularly in the Western Mesara Plain and at Knossos.

The vessels feature stamped decorations in which a single element is repeated in sequence. Their production method offers a parallel with the Phaistos Disc because both involve impressions made with stamping devices. The pottery also has images resembling some of the disc's signs.

Sanavia identified striking comparisons for six Phaistos Disc signs. Most of the Protopalatial impressed pottery at Phaistos was recovered during excavations conducted between 1950 and 1966. During Pernier's original campaigns, only a small number of impressed fragments were discovered, and these did not show relevant iconographic similarities with the disc.

The evidence points to around 1750 BCE

The Phaistian potmarks and impressed fine ware also offer hints about when the disc was made. The comparisons point most strongly toward the beginning of the Neopalatial period, around 1750 BCE.

However, the possibility that the disc originated during the final phase of the preceding Protopalatial period, Middle Minoan IIB, cannot be excluded.

What might the Phaistos Disc have been used for?

The disc does not appear to have been a utilitarian object like a gameboard, nor does it appear to have been a regularly consulted administrative document such as a calendar. It also does not seem to have been something temporarily preserved for later disposal.

The repeated combinations of signs strongly indicate that its inscription had a religious or magical character. Its intentional firing and unusual spiral design further suggest that it may have been created for display.

From an archaeological perspective, the disc therefore fits more closely into the cultural setting of Phaistos during the transition between the Protopalatial and Neopalatial periods. Writing was already known at Phaistos, while the disc also fits into the skilled local tradition of ceramic production.

Its similarities with contemporary potters' marks and impressed ware, along with the use of stamping devices in Minoan sealing practices, provide a broader context for understanding the artefact.

The message itself remains undeciphered. Yet the archaeological evidence suggests that the Phaistos Disc may no longer need to be viewed as an entirely isolated object. Its relationship with other material from Phaistos offers a starting point for future attempts to understand what its mysterious inscription was intended to communicate.
