Ideas:

1. The glyph for Venus is similar to that of Jupiter's, so similar as to suggest a close connection. Astronomically seen I cannot find any other connection than that both planets are bright in the sky. On the earthly plane Venus might represent the queen in the same way as Jupiter represents the king, cfr the Stranger King.

2. But the glyph for Venus has her right arm longer (the arm pointing downwards), ending more close to the earth than that in the glyph for Jupiter.

I believe this can be read both as a sign that Venus often is close to the horizon in the west - the direction pointing downwards to the underworld - and as a sign (on the earthly plane) that the season to plant has arrived, to put into the ground, to insure a crop next year.
