Toward the edges of the Sun, again, are very brilliant and highly luminous regions, which generally surround the spots, and have been termed _faculæ_ (_facula_, a little torch).
He considers it indeed "highly probable that the preparatory sign of a new spot is always a small, bright patch of facula."
: "Si autem velut a lumine lumina accensa sunt ... velut verbi gratia a facula faculæ, generatione quidem et magnitudine fortasse distabunt ab invicem; eiusdem autem substantive cum sint cum principe emissionis ipsorum, aut omnes impassibiles perseverant aut et pater ipsorum participabit passiones.
Neque enim quæ postea accensa est facula, alterum lumen habebit quam illud quod ante eam fuit. "
• Regnabit Dominus in facula &c 4] Ante faecula re* gnavit Chriftus finecarne; regnavitefiam in carn* in faecula.
