Clytemnestra, in Greek mythology, was the wife of Agamemnon, and the half-sister of Helen of Troy.
In Aeschylus' Oresteia, she murders Agamemnon – said by Euripides to be her second husband – and the Trojan princess Cassandra, whom Agamemnon had taken as a war prize following the sack of Troy; however, in Homer's Odyssey, her role in Agamemnon's death is unclear and her character is significantly more subdued.
Two Shintō shrines on Awaji Island are associated with the creation myth of Japan (国生み神話) in the earliest chronicles Kojiki and Nihon Shoki. At Onokoro Island Shrine (自凝島神社), visitors are encouraged to perform rituals to sacred stones for good fortune. The sekirei stone (鶺鴒石) is for couples, with a white and red cord, and I was surprised that my wife grasped my hand and prayed as we held the cords.
We also went to Izanagi Shrine (伊弉諾神宮), dedicated to the two founding gods or pillars (二神、又は二柱) of the archipelago. Worshippers believe that the founding gods dwell in the 900-year-old husband-and-wife camphor tree (夫婦楠). We have seen a similar tree at Ōmiwa Jinja in Nara (大神神社) where two trees merged into one at the base. We also noticed a connection to the Onokoro Island Shrine at the Izanagi Shrine, a small sekirei monument to married couples (夫婦鶺鴒像), and both sites included a bird motif.
