You have in this work, now newly born and published,

diligent reader, the movements of the stars, both fixed

and wandering original Latin: "erraticarum." This refers to the planets, which appear to "wander" across the sky compared to the "fixed" stars., restored from both ancient

which you can calculate these same movements for any time

as easily as possible. Therefore buy, read, and enjoy.
