When they became acquainted with Crete, the Mycenaeans were influenced by the Minoans, not only in artistic matters but also in the whole system of organization of their socio-economic life and most importantly in the field of religion; but a thorough examination shows that the ancestral religion of the Mycenaeans differs from the Minoan one, even if at first sight there are similarities. The Mycenaean religion is polytheistic; the nameless Cretan Great goddess is worshipped but also a number of male gods (though without any iconography), named Zeus, Poseidon or Hermes; syncretism was its central characteristic. In later times, as the Cretan spiritual dominance waned, typically Minoan symbols lost their prime symbolic power to the benefit of Mycenaean conceptions. Official and popular religion, the function of open-air and built sanctuaries, the symbols, rituals and Linear B tablets are subjects constantly debated, and yet the essence of Mycenaean religion, the related ideas and concepts escape us.

IIn the LH I period a social organization appears and a wealthy ruling class emerges. The foundation of the ‘palace’ structure is laid and the ‘ideology of power’ as well. The period is mainly known from tombs, the shaft graves excavated by Heinrich Schliemann in Mycenae being the most celebrated. The finds produced by the two Grave circles of Mycenae, remarkable for their variety and wealth, give plentiful information about the burial customs, the identity of the deceased and the art of the period. Stonework for precious vases, metalwork in gold, electrum or silver show sophisticated techniques – repoussé, inlaying, cloisonné – in the fashioning of cups, rhyta, weapons with decorated hilts. Outstanding are the Silver Siege Rhyton, the daggers with elaborate inlaid blades and the funerary masks, a special offering; also the distantly coming amber used in jewellery. Faience items bear Minoan influence, as do the seals and signet rings, a special category.

The first Linear B tablets were found by Evans in Knossos, many more by Blegen in Pylos in 1939 and progressively in all Mycenaean centres. Crete had three writing types Hieroglyphic, Linear A being more widespread, still undeciphered, and Linear B which descends from Linear A and appeared in mainland Greece around 1400 BC. After many endeavours, it has been deciphered in 1952 revealing a syllabic script for an early stage of Greek language. The debate of concordance between the Knossos and the Pylos tablets followed and is still alive. The inscribed clay tablets, simply dried, were baked by the fires that destroyed the palaces and thus preserved. They are administrative documents mostly inventory or tax statements teaching us a lot about Mycenaean life, palatial system, social hierarchy but no literature or history.
