Consider all four symbols together instead of obsessing over zoso to get the full context. Zoso is saturn/lucifer, etc. jones' symbol represents expelling evil spirits. bonhams symbol represents the holy trinity. plant's represents truth. Context (possibly): Saturn will "expell the evil spirits" of the "holy trinity". this is "truth" not gonna provide links i'm too lazy and drunk. have fun. btw...led zeppelin not my all time favorite, but pound for pound the best band that ever was.
