Linear A is the designation given to one of two scripts used by the Minoans. Many attempts have been made to decipher the script, variously linking it to Greek, Etruscan, Tyrhennian, Anatolian or Persian^(d)  languages.  Patrick Archer moved further east for a solution, claiming that Linear A is possibly related to Chinese pictographs! One of the more exotic solutions was offered by the American, Stuart Harris, who identified the language as being related to Finnish. Harris followed Felice Vinci in identifying the Baltic as the source of much of Greek culture including Homer’s epics^(b). So far no one theory has gained general acceptance.
