¶ What degrees are.
IN the owlde tyme theyr maner was to measure the earth and the woorlde by furlonges, pa••es, and fiete, as is to reade in Plinie, Strabo, and ••ther wryters. But after that P••olome founde degrees a hundreth and fiftie yeares after the death of C••ryst, that maner of accompte was receaued as the best.* 1.1 Ptolomie diuided all the hole body and face of the land and sea into three hundreth and sixtie degrees of length o•• lō¦gitude: and other as many degrees of bredth or latitude: so that the hole globe of the baule beinge rounde, conteyneth as much ••n latitude as longitude.* 1.2 He assigned lykewyse to eue¦ry degree three score myles, whiche make .xvii. Spany••she lea••ues and a halfe: In such sorte that the globe or baule of the earth mea••ured directly by any of the foure partes of the same,* 1.3 cont••yne••h ••n circuite sy••e thou••and and two hundreth leaques. This computacion and measurynge, is so certeyne, th••t as it is approued of all men and founde ••rewe by experi∣ence, so much the 〈◊〉〈◊〉 is it to bee commended and had in ad¦miration for 〈…〉〈…〉 ••ereof was iudged so dyfficult by Iob and 〈…〉〈…〉, that no ••••an had founde the mea∣sure of 〈◊〉〈◊〉 of the ••ame. They name those degrees of lon∣g••tude,* 1.4 that they accompte from soonne to soonne by the E∣quinoc••iall line which reacheth from the East to the Weste by the myddle of the globe or baule of the earth. These can not well bee obseru••d, forasmuch as in this ••ract of heauen, there is no fyxe or permanent signe whereunto the pylots maye di∣recte theyr eyes or instrumentes. For the soonne, althowghe i•• be a moste cleare signe, yet doothe it dayely chaunge the place of rysynge and faulynge,* 1.5 and keepethe not the same course the day folowynge as the Astronomers a••firme. And al¦thowgh there is no number of thē that in trauaylyng strange landes and seas haue spent theyr gooddes and almoste theyr wyttes to fynde the degrees of longitude withowt errour as are found the degrees of latitude & heyght,* 1.6 yet is there none that hytherto hath any trewe knowleage therof. The degrees of latitude or altitude, are they that are accompted from the north pointe to the sout••, the commen••uration or mea••uring whe••by, is most certeine by reason that the north starre is per¦mane* 1.7
