Ideas:

1. The efforts of the Maya indians to 'capture' Venus in the 'net' of the periods of the Moon implies that these two 'planets' have similarities, otherwise the capture would be impossible.

2. First of all there is the similarity expressed by the 'measurement staff', i.e. both planets function as watches; you can watch them and learn what time it is. And as time is impossible to abstract from space - reality contains nothing but events - these planets not only give time but also must govern your reality.

Venus has a 5-fold event-symmetry, like the fingers of a mighty hand - the hand of Mahuika? No wonder the Mayas feared Venus. Definitively it is a magic light in the sky.
