Venus makes a pentagram pattern in eight years. I posted a diagram in the photos section... In eight years the eclipse will happen again, completing a full (okay, minus two degrees) pentagram.

If you have a good diagram, feel free to post it as well.

The fivepointed star was a sacred symbol in Sumeria and pre-Columbian America, although in the latter with rounded points, and may have been a symbol of Venus based on its orbit. I think the Mayan culture had succeeded in discovering the pentagram shaped orbit. They certainly had advanced knowledge of the timing of the appearances of the Morning star and the Evening star, that is, the orbit of the planet Venus.

In any event, the symbol for Ishtar/Venus has almost always been an eight pointed star. Don't know what to make of that.
