Whilst researching something else, I came upon the following story from Greek myth, that reminded me of this card and my previous point about individual responsibility. The Renaissance itself saw the revival of classical Greek and Roman texts so I don't think that this is too much of a stretch to refer this card to a Greek myth.
I came across a myth related to Artemis, Apollo and Orion. Artemis and Apollo are twins, they are both archers in one way or another. Artemis became associated with the Moon and her twin brother Apollo with the Sun. So perhaps one way of looking at this card, could be as Artemis and Apollo.
In some stories Artemis fell in love with Orion, a hunting companion and forgot her duty to illuminate the sky. Hence, her individual responsibility. The story varies on how exactly Orion was killed, but it does say that Apollo was unhappy about the union between Artemis and Orion. One version states that Apollo saw Orion swimming in the sea and dared his sister that she could not hit a small speck (that was Orion) in the sea. Not being one to back down from the challenge to her archery skills she shot an arrow and killed Orion. When she found out what she had done she put his body among the stars and he is now the constellation, Orion.
It might be just me but I found this story fascinating in terms of this card. It also interested me to learn that until the Renaissance, Artemis was not depicted in art with the moon. Another fact that interested me is that Orion, the constellation, borders the sign of Gemini, which is the astrological attribution for this card.
Anyway, I thought I'd share something that I found interesting.
