The first movable. Sir Thomas Browne (Religio Medici, p. 56, 27) uses the phrase, “Beyond the first movable,” meaning outside the material creation. According to Ptolemy the “primum mobile” (the first movable and first mover of all things) was the boundary of creation, above which came the empyrean heaven, or seat of God.
