The Tiryns Signet Ring, Late Helladic period, c. 15th century BC
This is the the largest known Mycenaean ring. It was found in a robber’s cache at Tiryns, a Mycenaean city of Argolis in the Peloponnese and is kept at the National Museum of Athens. The ring is thought to have been made by a Cretan artist visiting Argolis and is a copy of a fresco at Tiryns.
It depicts a procession of lion-headed daemons holding libation jugs and moving towards an enthroned goddess. The goddess wears a long chiton and raises a ritual cup. Behind the throne is an eagle, a symbol of dominion. The sun and moon are shown in the sky above.
The Late Helladic period (c. 1500-1060 BC) is the time when Mycenaean Greece flourished under new influences from Minoan Crete and the Cyclades. Around 1400 BC, the Mycenaeans extended their control to Crete, the center of the Minoan civilization. Crete had been crippled by the eruption of Thera (Santorini), thus leaving it vulnerable.
