Minoan civilization civilization has been described as the earliest of its kind in Europe, with historian Will Durant calling the Minoans "the first link in the European chain". The Minoan civilization is particularly notable for its large and elaborate palaces, some of which were up to four stories high, featured elaborate plumbing systems and were decorated with frescoes. The most notable Minoan palace is that of Knossos, followed by that of Phaistos. The Minoan period saw extensive trade between Crete, Aegean and Mediterranean settlements, particularly the Near East. Through their traders and artists, the Minoans' cultural influence reached beyond Crete to the
Minoan civilization among the most well-supported examples known. Because their language has yet to be deciphered, it is unknown what kind of government was practiced by the Minoans, though the palaces and throne rooms indicate a form of hierarchy. A fresco of saffron-gatherers at Santorini is well-known. The Minoan trade in saffron, the stigma of a naturally-mutated crocus which originated in the Aegean basin, has left few material remains. According to Evans, the saffron (a sizable Minoan industry) was used for dye. Other archaeologists emphasize durable trade items: ceramics, copper, tin, gold and silver. The saffron may have had a religious significance.
