This is a printed document, from around 1700 before the current era, long before printing was invented!

The Phaistos disc was discovered in 1908 in a Bronze-Age building, a palace, at Phaistos in SW Crete. Could the Phaistos disc be a forgery? That would be a very elaborate hoax to perpetrate: making 45 stamps to imprint on clay, on both sides of the object, and printing 30 clusters of signs (words or phrases ?) on one side and 31 on the other. I know personally two different scholars (out of a host of hopefuls) who have published confident attempts at decipherment (both read it as Hellenic, but produce entirely different transcriptions and translations). My observations on it, after looking at all the other scripts of Crete (and Cyprus) is that it does not belong to the same family as Linear B (used for Mycenean Greek texts).
There is a line of development in Crete from a set of pictographs to stylized Linear A characters (language uncertain) and even more stylizedLinear B; and on Cyprus a derived syllabic script from the same source (through Linear A), used for a Greel dialect and other languages. My judgement is that the Cretan pictographs and the Phaistos glyphs (in spite of similarities and apparent correspondences) do not belong to the same system. There were two different but related writing systems on Crete: (1) the Knossos script (northern), a picto-phonetic syllabary > Linear A and B; (2) the Phaistos script (southern), a picto-phonetic syllabary. Looking at the 30 accountancy tablets from Phaistos (as distinct from adjacent Hagia Triada, where the Linear A script was used, a stylized form of the northern picto-phonetic script), most seem to be Linear A, but some (PH 8, 9, 13, 15, 17, 26) have signs known from the Phaistos Disc, and notably PH 12:PhD 22 (cuttlefish, Greek sépia, Linear B SA), PhD 27 ( hide, talent?).
PH 13 has a fish (Phaistos Disc sign 35), which is not found in the
northern picto-syllabary or its descendant, Linear A.
Thus the Phaistos script has its own set of signs, but some of them are
shared with the Knossos syllabary.
The 45 characters on the Phaistos Disc (after Arthur Evans)
Or perhaps it will. If enough signs are common to both systems, and we
substitute the known values from Linear B, then we are on our way
with a flying start. I could argue for at least 20 correspondences out of
45 (the number of separate signs on the Disc). This was the approach of
Steven Fischer in his attempt at decipherment.
And the Arkalokhori Ax has 15 characters, some of them duplicates, with apparent connections to the Phaistos Disk set of signs, and/or to the Knossos inventory.
