IT happeth somtyme that the sonne leseth his clere∣nes & the lyght in the playn daye / ffor it goth as to declyne / & is called in latyn eclipse / This eclipse procedeth bicause of defaulte of light / and it happeth in this manere
that whan the mone whiche is vnder the sonne cometh right bytwene vs and the sonne / thenne in the right lygne it behoueth that toward vs the mone taketh and reteygneth the lyght of the sonne on hye / so that it semeth to vs that is defaylled / ffor the mone is not so pure that the sonne may shyne ouer her / and thurgh her as thurgh an other sterre / Alle lyke as of a candell / whiche is sette ferre fro your sight / and after ye helde your honde right to fore the candell / thenne ye shold not see nothyng therof / And the more right ye holde your hand bytwene / the more lasse shold ye see this candele / And somoche ye may sette your hand right to fore your ••yen and so ferre / that ye shold see nothyng therof / In this maner I telle yow of the eclypse that bytwene the Sonne and the Mone is not one waye comune / but the mone goth an other waye whiche destourneth her a lytil from the Sonne / wherfore vs byhoueth to vnderstande that the mone goth oftymes whan she is bytwene vs and the Sonne som∣tyme aboue and otherwhyle bynethe / here and there as she riseth and declyneth / But whan she passyth in the right lygne euen bytwene vs & the sonne / thenne taketh the mone fro vs the lyght & clernes of the sonne / in suche wyse as we may not clerly see her in that paas / ffor thenne shadoweth she therthe / and kepeth the rayes of the sonne that they may not shyne on therthe / & they that ben in this parte / haue in their sight ye shadowe behynde them But it apperith not comunely to alle men thurgh al the world / ffor the mone is not so grete nowher nygh̄ as all therthe / therfor she shadoweth not all / but only where
she is in the right lygne bytwene therthe and the sonne / And thyder the philosophres were wont to goo / where as they kn••we it / ffor by their wyt & studye they had lerned for to approue the daye and tyme whan suche thynges shold happe / by whiche they preuyd plente of thynges / wherfore they preysed moche our lord / Thus see we here byneth the eclipse of the sonne aboue vs / whan the mone is right vnder the sonne for as moche as she is bynethe the sonne and aboue vs / And thenne the sonne passeth the right lygne and goth departyng and wythdrawyng so moche that
