Something that’s very interesting about Minako/Sailor Venus is that, not only is she the character with the most mythological references to her namesake, she is the only character in the series to be called a goddess or anything divine.
There’s also this fantastic panel, which states that the Silver Millennium version of Sailor Venus had the same origin as the mythical Aphrodite.
In Classical Mythology, Aphrodite/Venus was born when Uranus, the personification of the sky, was castrated by his son Cronus (aka Saturn). When his severed genitals dropped into the ocean, the foam from them gave birth to Aphrodite (hence her name, which means “foam-arisen”) while the Erinyes (or the Furies) were born from the blood that was spilled. Eventually, Aphrodite emerged from the foam of the sea, fully grown and floating on a scallop shell.
While our Venus’s origin story presumably didn’t involve castration (hopefully, although knowing Minako…), her marine origin remains intact. In addition, a drop of the foam she was born from crystalized and turned into a gem, which was then revered as a Venusian treasure.
So I have to wonder, which came first in the SM universe: The myths or the Senshi? I think that, during the Silver Millennium, the Senshi (as well as the other immortal inhabitants of the Silver Millennium) inspired Classical Mythology, and over time the myths began to take their own shape and deviate from the source material (especially after the fall of the Silver Millennium).
