Broblemajam propositum ia soluetar:
Dato Horologio exacto datur lous sideris in
mundo, momento dato, locus sideris inquami
id est ccus longitudo & latituao. Latitudo
quidem si sidus cum polo immobili; Longitudo
si cum centro seu cum meridiano primo interra
ut immotili supposita, ducto comparetur
Latitudo ejus si quidem sit stella fixa, sempereadem
ac proinde cognita est. Si planeta, determinat,
determinato ejus loco in fodiaco quem nobis Ephes
merides monstrant, hora, minutoue dato.
Longitudo sideris cognositur hora data, nam
si fira est, scinus quantum a Mercdranoprimo-
eamabesse, nunc neusse sit, quia fixarum reuo,
lutione sunt semper aequales, e praecise 2V. horis
absoluuntur. Si ergo conctet nobis, quo in loco
tempore quodam cognito, aliqua fuerit fira,
constabit nobis semper quo in loco, tempore quo
cunque dato eadem fixa, imo alia quaecunque futurasit.
Nam ipsarum fixarum motus peculiaris, a motu
nc
primi mobilis diuersus, cum non nisi post multa
sacula sensitilis fiat, in calculum venire necpotest,
nec detet.
Sin blaneta est consta,
bit nobis ulique per easdem Ephemerides quantum
nunc absit a meridiano primo versus ortum
occasumque, nam etsi revolutiones ejus non sint
revolutionibus fixarum aequales, differentia
tamemrobis cognita est jua supputari potest
potuita. Sed in eam quidem rem planetis praeter
solem lunamque (. quorum exploratius satis curs est.)
opus non haberuis, quoties enum caeteri planetae
videri possant, poterant etiam fica videri, qua
ram asus certe expeditior.
