I refreshed my memory a bit. Linear Elamite {linear? Linear B [??] confusing enough} and Proto-Elamite. Apparently affected by Akkadian.
***the Phaistos Disk. The letter calls it a century old fraud***
The Phaistos Disk is questionable. I think the thermoluminescence testing would help.
If the Phaistos Disk had been announced by James Mellaart, I'd agree it would be questionable. :^) The disk text was was made by dies/stamps, making it the earliest known moveable type print job in the world. The characters used are from Anatolia, but as it is the sole sample of its kind, and longest known text using the character set (as far as I know), it probably won't be cracked to the satisfaction of anyone other than the each of the purported translators. :^)
