I see I wrote that Saturn rules iron in my post about Mrs T. It’s a bit more complicated than that. She has Saturn in Scorpio, which is ruled by the iron planet Mars. In Western astrology, Saturn rules lead, Mars rules iron.
However, in Vedic astrology, Saturn does rule iron.
I’ll leave it there, shall I?
OK. Here’s the traditional western list
Sun – Gold
Mercury – Quicksilver
Venus – Copper
Jupiter – Tin
Mercury – Zinc
Venus – also Silver
