Wher-for, whan that the 5 degree of thy sonne falleth by-twixe two almikanteras, or elles yif thyn almikanteras ben graven with over gret a point of a compas, (for bothe thise thinges may causen errour as wel in knowing of the tyd of the day as of the verrey assendent), thou most werken in this wyse. Set the degree of thy sonne up-on the heyer 10 almikanteras of bothe, and waite wel wher as thin almury toucheth the bordure, and set ther a prikke of inke. Set doun agayn the degree of thy sonne up-on the nethere almikanteras of bothe, and set ther another prikke. Remewe thanne thyn almury in the bordure evene amiddes bothe prikkes, and this wol lede iustly the 15 degree of thy sonne to sitte by-twixe bothe almikanteras in his right place. Ley thanne thy label over the degree of thy sonne; and find in the bordure the verrey tyde of the day or of the night. And as verreyly shaltow finde up-on thyn est orisonte thyn assendent. And for more declaracioun, lo here thy figure. 20 6. TO KNOWE THE SPRING OF THE DAWING AND THE ENDE OF THE EVENING, THE WHICH BEN CALLED THE TWO CREPUSCULIS: [AD COGNOSCENDUM ORTUM SOLIS ET EIUS OCCASUM, QUE VOCATUR VULGARITER CREPUSCULUM.] Set the nadir of thy sonne up-on 18 degrees of heighte among thyn almikanteras on the west syde, and ley thy label on the degree of thy sonne, and thanne shal the poynt of thy label schewe the spring of day. Also set the nadir of thy sonne up-on 18 degrees of heighte a-mong thyn almikanteras on the est side, and ley over 5 thy label up-on the degree of the sonne, and with the point of thy label find in the bordure the ende of the evening, that is, verrey night. The nadir of the sonne is thilke degree that is opposit to the degree of the sonne, in the seventhe signe, as thus: every degree of Aries by ordre is nadir to every degree of Libra 10 by ordre; and Taurus to Scorpion; Gemini to Sagittare; Cancer to Capricorne; Leo to Aquarie; Virgo to Pisces; and yif any degree in thy zodiak be dirk, his nadir shal declare him. And for the more declaracioun, lo here thy figure. 7. TO KNOWE THE ARCH OF THE DAY, THAT SOME FOLK CALLEN THE DAY ARTIFICIAL, FROM THE SONNE ARYSING TIL HIT GO TO RESTE. [AD COGNOSCENDUM ARCHUM DIEI, QUEM VULGUS VOCAT DIEM ARTIFICIALEM, IN HOC, AB ORTU SOLIS USQUE AD OCCASUM.] Set the degree of thy sonne up-on thyn est orisonte, and ley thy label on the degree of the sonne, and at the poynt of thy label in the bordure set a prikke. Turn thanne thy riet aboute til the degree of the sonne sit up-on the west orisonte, and ley thy label up-on the same degree of the sonne, and at the point of 5 thy label set a-nother prikke. Rekne thanne the quantitee of tyme in the bordure by-twixe bothe prikkes, and tak ther thyn ark of the day. The remenant of the bordure under the orisonte is the ark of the night. Thus maistow rekne bothe arches, or every porcion, of whether that thee lyketh. And by this manere 10 of wyrking maistow see how longe that any sterre fix dwelleth above the erthe, fro tyme that he ryseth til he go to reste. But the day natural, that is to seyn 24 houres, is the revolucioun of the equinoxial with as moche partie of the zodiak as the sonne of his propre moevinge passeth in the mene whyle. And for the 15 more declaracioun, lo here thy figure. 8. TO TURN THE HOURES IN-EQUALES IN HOURES EQUALES. [AD CONVERTENDUM HORAS INEQUALES IN HORAS EQUALES.] Knowe the nombre of the degrees in the houres in-equales, and departe hem by 15, and tak ther thyn houres equales. And for the more declaracioun, lo here thy figure. 9. TO KNOWE THE QUANTITEE OF THE DAY VULGARE, THAT IS TO SEYEN, FROM SPRING OF THE DAY UN-TO VERREY NIGHT. [AD COGNOSCENDUM QUANTITATEM DIEI VULGARIS, VIZ. AB ORTU DIEI USQUE AD NOCTEM.] Know the quantitee of thy crepusculis, as I have taught in the chapitre bi-forn, and adde hem to the arch of thy day artificial; and tak ther the space of alle the hole day vulgar, un-to verrey night. The same manere maystow worke, to knowe the quantitee of the vulgar night. And for the more declaracioun, lo here the 5 figure. 10. TO KNOWE THE QUANTITE OF HOURES IN-EQUALES BY DAY. [AD COGNOSCENDUM HORAS INEQUALES IN DIE.] Understond wel, that thise houres in-equales ben cleped houres of planetes, and understond wel that som-tyme ben they lengere by day than by night, and som-tyme the contrarie. But understond wel, that evermo, generaly, the hour in-equal of the day with the houre in-equal of the night contenen 30 degrees of the 5 bordure, whiche bordure is ever-mo answering to the degrees of the equinoxial; wher-for departe the arch of the day artificial in 12, and tak ther the quantitee of the houre in-equal by day. And yif thow abate the quantitee of the houre in-equal by daye out of 30, than shal the remenant that leveth performe the houre 10 inequal by night. And for the more declaracioun, lo here the figure. 11. TO KNOWE THE QUANTITE OF HOURES EQUALES. [AD COGNOSCENDUM QUANTITATEM HORARUM INEQUALIUM.] The quantitee of houres equales, that is to seyn, the houres of the clokke, ben departed by 15 degrees al-redy in the bordure of thyn Astrolabie, as wel by night as by day, generaly for evere. What nedeth more declaracioun? Wher-for, whan thee list to know how manye houres of the clokke ben passed, or any part of 5 any of thise houres that ben passed, or elles how many houres or partie of houres ben to come, fro swich a tyme to swich a tyme, by day or by nighte, knowe the degree of thy sonne, and ley thy label on it; turne thy riet aboute ioyntly with thy label, and with the point of it rekne in the bordure fro the sonne aryse un-to 10 the same place ther thou desirest, by day as by nighte. This conclusioun wol I declare in the laste chapitre of the 4 partie of this tretis so openly, that ther shal lakke no worde that nedeth to the declaracioun. And for the more declaracioun, lo here the figure. 15 12. SPECIAL DECLARACIOUN OF THE HOURES OF PLANETES. [SPECIALIS DECLARACIO DE HORIS PLANETARUM.] Understond wel, that evere-mo, fro the arysing of the sonne til it go to reste, the nadir of the sonne shal shewe the houre of the planete, and fro that tyme forward al the night til the sonne aryse; than shal the verrey degree of the sonne shewe the houre of the planete. Ensample as thus. The 13 day of March fil 5 up-on a Saterday per aventure, and, at the arising of the sonne, I fond the secounde degree of Aries sitting up-on myn est orisonte, al-be-it that it was but lite; than fond I the 2 degree of Libra, nadir of my sonne, dessending on my west orisonte, up-on which west orisonte every day generally, at the sonne ariste, entreth 10 the houre of any planete, after which planete the day bereth his name; and endeth in the nexte s |
