Since Jimmy was so interested in the Occult, I thought the "Zo" part was a nod to Zoarastrianism. Even the script of the Z is reminiscent of Middle Eastern alphabets (Arabic/Persian). And the "So", an abbreviation for Solar perhaps. Or instead of Solar, how about Son, as in "Son of". The "S" also conveniently doubles as a spirit coming out of Alladin's lamp there at the bottom. And that horizontal bar firmly connecting the two "o"s: maybe that represents his outstretched arms transcending time between the ancient past and the present, with a firm grip on both. Maybe he sees himself as the spiritual son of a deity from an ancient mystery religion, Mithraism/Zoarastrianism. It is very beautiful, elegant, and well thought out. I would be surprised if I am completely wrong. Jimmy Page is too smart and too deep for it to be something completely disconnected from mystical history.
