Jerome M. Eisenberg, writing in the July/August issue of the magazine Minerva, provides a compilation of the scholarly (and non-scholarly) ideas about and attempted translations of the disk, and concludes that the disk is a forgery...
...The translation compilation alone contains such entertainments, from the mystic ("Helmsman's-rhythm-beating-call of the blossoming radiant heaven's tree dweller"), to the romantic ("Blissful lady of the labyrinth, blissful Isonoia, lady of the coffins") to the political ("Hear ye Cretans! Quick, quick") to the instructional ("Enter the grove of Elaia: Ignite smoothened wood all around"), ...
Proving the Phaistos disk a fake is going to be difficult. Eisenberg points out that the purposely stamped and deliberately fired disk is unlike any other Minoan script. Those found at Knossos were drawn into soft clay and accidentally fired.
No they were not accidentally fired! They were burnt as was the custom - as gifts to the dead.
The Secrets of Crete. Knossos wasn't a palace, it was a Temple of the Dead.
