A Minoan seal stone discovered during the most recent excavations at Vrysinas, near Rethymnon, Crete. At one time, Vrysinas was an important Minoan peak sanctuary; the seal dates from the First Palace period (1900-1700 B.C.) It is red jasper, and is carved on all four sides with Minoan hieroglyphics which are not Linear A. In fact, the seal stone appears to be the earliest example of Minoan Hieroglyphic script yet discovered.
