An olympic spirit entry records one of the seven governors the Arbatel de magia veterum assigns to the seven classical planetary spheres, first printed in Latin at Basel in 1575 and known in English chiefly through Robert Turner's 1655 translation, a text that names each spirit, its ruling planet, the number of provinces of the world it is said to govern, and the specific powers, alchemy and the secrets of nature for Aratron's sphere of Saturn among them, that the Arbatel itself attributes to it.
An entry records a spirit's ruling planet, its documented powers as the Arbatel's own text states them, and the text's own uncertain authorship, since the Arbatel was printed anonymously and neither states when it was originally written nor names the person who wrote it, a genuine gap in the record an entry states honestly rather than filling with an invented attribution.
An entry also records where a separate grimoire tradition, Agrippa's own Three Books of Occult Philosophy or John Dee's Heptarchia Mystica among them, sets a different spirit or intelligence over the same planetary sphere under an entirely different name, since these are documented, separate systems rather than variant spellings of the Arbatel's own seven.
