It would appear that the dynamics of the two married protagonists of Greek and Roman mythology Zeus (Jupiter) and Hera (Juno) is one of a jealous wife chasing a promiscuous husband.
In order to conceal his escapades, Zeus constantly makes use of his shapeshifting abilities. Thus, he transforms himself into a cloud (he hid himself within a cloud with Io), a golden shower with Danae, a swan with Leda, a bull with Europa, depending on whether he needed to be charming and beautiful or powerful and frightening in his conquest.
According to old European beliefs, a candle made of the fat from a malefactor who died on the gallows, virgin wax, and Lapland sesame oil (the candle could only be put out with milk), and the hand having come from the said hanged criminal, lighted and placed in the Hand of Glory (as in a candlestick) would have rendered motionless all persons to whom it was presented. The Hand of Glory also purportedly had the power to unlock any door it came across.
The legend is traceable to about 1440, but the name only dates from 1707. It was originally a name for the mandrake root (via French “mandragore” and thus “hand of glory”) that became conflated with the earlier legend. The confusion may have occurred because mandrakes are said to grow beneath the bodies of hanged criminals.
