Meanwhile in the West
Structurally similar to Tycho Brahe's later model (late 16th c.).
Fair to say
Still geocentric overall — not full heliocentrism.
Path to modern innovation
A sophisticated planetary model predating European equivalents.
Builds on
Transmission
Independent development before Tycho.
