Linear A

Linear A is an undeciphered script used in ancient Crete. Its decipherment is one of the "holy grails" of ancient scripts, and it has attracted more than its fair share of crackpot theories.

While the related writing named Linear B was deciphered in the 1950s by Michael Ventris, Linear A remains unsolved. Though the two scripts share many of the same symbols, using the syllables? associated with Linear B in Linear A writings produces words that are unrelated to any known language. This language has been dubbed Minoan?, and corresponds to a period in Cretan history prior to a series of invasions by [Mycenean Greeks]? some time around [1400 BC]?.

As the Minoan language is lost to the modern day, it is unknown whether or not this is the correct decipherment, or merely gibberish being generated by an incorrect mapping of symbols? to sounds. Until further breakthroughs are made, the content of documents written in Linear A remains a mystery.
