Phaistos Disc

The Phaistos Disc (Phaistos Disk, Phaestos Disc, Festos Disc, Greek: Δίσκος της Φαιστού) is a curious archaeological find, most likely dating from about 1700 BC. Its purpose and meaning, and even its original geographical place of manufacture, remain disputed, making it one of the most famous mysteries of archaeology.

Discovery

The Phaistos Disc was discovered in the basement of room XL-101 of the Minoan palace-site of Phaistos, near Hagia Triada, on the south coast of Crete. Italian archaeologist Luigi Pernier recovered this remarkably intact "dish", about 15 cm in diameter and uniformly just over 1 cm thick, on July 3 1908.

Archaeological context

Luigi Pernier discovered the disc 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 context 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, a few inches south-east of the disk, 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 explosive eruption of the Santorini volcano that affected large parts of the Mediterranean region ca. 1628 BC.

Physical description

Side A (Original).

Side B (Original).

The inscription was made by pressing pre-formed hieroglyphic "seals" into the soft clay, in a clockwise sequence spiralling towards the disc's center. It was then baked at high temperature.

This unique object is now on display at the archaeological museum of Heraklion in Crete, Greece.

Glyphs

There are a total of 241 figures on the disc. Many of the 45 different glyphs represent easily identifiable every-day things. In addition to these, there is a small diagonal line that occurs underneath the final sign in a group a total of 18 times. The disk shows traces of corrections made by the scribe in several places. The 45 symbols have been numbered by A. Evans from 01 to 45, and this numbering has become the conventional reference used by most researchers. Some symbols have been compared with Linear A characters and assigned Linear B values by Fischer, Timm (2005) and others.

01: a walking human figure, occurring 11 times.

02: The most frequent symbol, the "Mohican" head in profile, occurring 19 times.

03: a bald head in profile, with "tatoo" or jewelery on the cheek, occurring twice.

04: "captive", a standing human figure with bound arms, occurring once (A.V)

05: child, occurring once

06: woman, occurring four times

07: "breast", a bell-shaped symbol, occurring 18 times

08: "hand-glove", occurring 5 times

09: "tiara", occurring twice

10: corn ear or arrow, ocurring four times (on side A only)

11: bow, occurring once (A.XIII)

12: dotted circle, "shield", occurring 17 times, compared with Linear B sign qe

13: "club", occurring six times

14: "yoke", occurring twice

15: pickaxe, occurring once

Strokes

There are a number of glyphs marked with an oblique stroke, the strokes are not imprinted but carved by hand and are attached to the first or last sign of a "word", depending on the direction of reading chosen. Their meaning is a matter of discussion. One hypothesis, supported by Evans, Duhoux, Ohlenroth and others, is that they were used to subdivide the text into paragraphs, but alternative meanings have been offered by other scholars.

Inscription text

There are 61 "words", 31 on side A and 30 on side B. The shortest words are two symbols in length, the longest seven symbols. The strokes are transcribed as '\'.

Direction of printing and Direction of reading

These can be determined by reconstructing the movements of the scribe. It can be shown from various epigraphical facts (overcuts, angular points on the spiral, corrections, etc.), that the text was written, spire by spire, alternating tracing of the spiral and printing of the signs, from the exterior to the center. Moreover, these epigraphical facts (for instance, the fact that most of the corrections were done on the spot by the scribe himself) show that the scribe was "composing" the text as he was printing it. There is therefore no way to dissociate the direction of reading from the direction of printing. All the scholars who have read the text in a counter-clockwise direction have been unable to present a reconstruction of the scribe's movements, coherent both with their hypothesis and with the epigraphical facts.

Attempted decipherment

A great deal of speculation developed around the disc during the 20th century. The Phaistos Disc captured the imagination of amateur archeologists. Alas, some of the more fanciful interpretations of its meaning are living classics of pseudoarchaeology. Many attempts have been made to decipher the code behind the disc's glyphs. Historically, almost anything has been proposed, including prayers, a narrative or an adventure story, a "psalterion", a call to arms, a board game, and a geometric theorem. While many enthusiasts still believe the mystery can be solved, scholarly attempts at decipherment are thought to be unlikely to succeed unless more examples of the glyphs turn up somewhere, as it is generally thought that there isn't enough context available for meaningful analysis.

This general opinion is nevertheless disputed by several scholars on the basis of the work of the mathematician Claude Shannon. Shannon's theory of unicity distance implies that, in theory, the text's length is sufficient for reaching only one decipherment that makes sense. However, once this valid solution has been found, it would be necessary to prove it, normally by deciphering another text in the same script. As no second disc has been found, no solution can be verified with absolute certainty.

Uniqueness

The uniqueness of this archaeological object may be invalidated by at least two other apparently related specimens - a votive double axe found by Spyridon Marinatos in the Arkalohori Cave, Crete, and a fragment of a smaller clay disk, found at Vladikavkaz, North Ossetia. But both inscriptions were engraved, not made with stamps. Moreover, the first contains only superficially similar hieroglyphics, and the second, interesting as it might prove, disappeared mysteriously. So far, the Phaistos Disc remains a hapax.

Character encoding

Although there is no official Unicode encoding for the symbols on the disk, the ConScript Unicode Registry has assigned a block of the Unicode Private Use Area to be used for the script. Two fonts include support for this area; Code2000 and Everson Mono Phaistos. The text on the disk is given on the second of these links; you can read that text if you have either of them installed.
