The Temple of Diana at Ephesus, which is also known as the Temple of Artemis; was one of the Seven Wonders of the Ancient World.
This could be another link to the green stone in the Head Room.
Originally built by the Amazons according to myth, and unlike the rest of Greece and Rome Artemis/Diana was worshiped mainly as a fertility goddess. Associated with the goddess Kybele, who was a mother goddess of Eastern lands. Kybele is believed to the the evolution of the Paleolithic and Neolithic Magna Mater, specifically Matar Kubileya. Artemis/Diana of Ephesus was also conflated with Hekate at the Ephesus Temple as an aspect of Diana according to Gaius Plinius Secundus (Pliny the Elder).
The cult of Diana of Ephesus viewed this goddess in a matter which closely resembles Hekate Soteira of the Chaldean Oracles in her role as Anima Mundi or World Soul, Axis Mundi or World Pillar and Cosmic Mother containing all men, animals and spirits within her.
The Amazons viewed the palm tree as sacred, being representative of their goddess and it is believed that the first Artemis/Diana of Ephesus was originally made out of a palm trunk. The goddess as a tree has great significance as a universal symbol of the Axis Mundi, often portrayed as a World Tree.
The palm tree was also believed to be sacred to the Hellenic Artemis, being a symbol of the island of Delos where she and her brother Apollo were born and many ancient coins from Ephesus depict a stag and a palm tree, the symbols of Artemis. It is believed that for this reason that the many breasts of the later Artemis/Diana of Ephesus statues are actually Palm-Dates as breasts, echoing back to the Amazonian palm tree goddess.
“Tradition relates that the amazons built a temple at Ephesus to house a primitive image of a goddess (later identified with Artemis), probably made of a palm trunk.”-Warner Rex, Encyclopedia of World Mythology
That earliest temple contained a sacred stone that had “fallen from Jupiter” called the Diopet and was later reportedly placed within the tower-like crown of the statue of Artemis/Diana. It was held as being a divine object, not only because it fell from the sky, but because it resembled Artemis/Diana of Ephesus. The Diopet held such reverence that it was paired together with the statue of Artemis/Diana in Acts 19:35 in the Bible, “And when the town clerk had appeased the people, he said, Ye men of Ephesus, what man is there that knoweth not how that the city of the Ephesians is a worshipper of the great goddess Diana, and of her image which fell down from Jupiter?” It’s interesting to also note that in Aradia, Gospel of the Witches it says that Diana fell to Earth, just as Lucifer had, to teach mankind witchcraft.
The City of Liverpool Museum acquired a stone from antiquarian Charles Seltman who bought it at Ephesus in the 1940s, claiming that it was the diopet.
“Liverpool’s Keeper of Archaeology, Dr. Dorothy Downes, says that just because it was purchased at Ephesus doesn’t prove its origins but that “it may well have come from one of the Ephesian temples.” The stone was originally a neolithic pestle of volcanic greenstone, she adds, “and was converted into an object of worship sometimes after c. 700 B.C. by reshaping and the addition of iron bands. Many people believed that that such stray finds were meteorites and therefore sacred.”- Elizabeth Pepper & John Wilcock, Magical and Mystical Sites: Europe and the British Isles
It isn’t that difficult to imagine that the Diopet might be Moldavite. It fell from the heavens/Jupiter, was supposedly in resemblance of Artemis/Diana of Ephesus (which is easy to imagine if you take into account that it might relate to the fact that most Moldavite pieces have an aerodynamic shape similar to palm leaves), and may have been similar to volcanic greenstone or volcanic glass.
