Litell Lowis my sone, I have perceived wel by certeyne evidences thyn abilite to lerne sciencez touchinge noumbres and proporciouns; and as wel considere I thy bisy preyere in special to lerne the Tretis of the Astrolabie. Than, for as mechel as a philosofre seith, 'he wrappeth him in his frend, that condescendeth 5 to the rightful preyers of his frend,' ther-for have I geven thee a suffisaunt Astrolabie as for oure orizonte, compowned after the latitude of Oxenford; up-on which, by mediacion of this litel tretis, I purpose to teche thee a certein nombre of conclusions apertening to the same instrument. I seye a certein of conclusiouns, 10 for three causes. The furste cause is this: truste wel that alle the conclusiouns that han ben founde, or elles possibly mighten be founde in so noble an instrument as an Astrolabie, ben un-knowe perfitly to any mortal man in this regioun, as I suppose. A-nother cause is this; that sothly, in any tretis of the Astrolabie that I have 15 seyn, there ben some conclusions that wole nat in alle thinges performen hir bihestes; and some of hem ben to harde to thy tendre age of ten yeer to conseyve. This tretis, divided in fyve parties, wole I shewe thee under ful lighte rewles and naked wordes in English; for Latin ne canstow yit but smal, my lyte 20 sone. But natheles, suffyse to thee thise trewe conclusiouns in English, as wel as suffyseth to thise noble clerkes Grekes thise same conclusiouns in Greek, and to Arabiens in Arabik, and to Iewes in Ebrew, and to the Latin folk in Latin; whiche Latin folk han hem furst out of othre diverse langages, and writen in hir owne tonge, 25 that is to sein, in Latin. And god wot, that in alle thise langages, and in many mo, han thise conclusiouns ben suffisantly lerned and taught, and yit by diverse rewles, right as diverse pathes leden diverse folk the righte wey to Rome. Now wol I prey meekly every discret persone that redeth or hereth this litel tretis, to have 30 my rewde endyting for excused, and my superfluite of wordes, for two causes. The firste cause is, for that curious endyting and hard sentence is ful hevy atones for swich a child to lerne. And the seconde cause is this, that sothly me semeth betre to wryten un-to a child twyes a good sentence, than he for-gete it ones. And 35 Lowis, yif so be that I shewe thee in my lighte English as trewe conclusiouns touching this matere, and naught only as trewe but as many and as subtil conclusiouns as ben shewed in Latin in any commune tretis of the Astrolabie, con me the more thank; and preye god save the king, that is lord of this langage, and alle that 40 him feyth bereth and obeyeth, everech in his degree, the more and the lasse. But considere wel, that I ne usurpe nat to have founde
