Of which signes, Gemini obeyeth 25 to Cancer; and Taurus to Leo; Aries to Virgo; Pisces to Libra; Aquarius to Scorpioun; and Capricorne to Sagittare. And thus ever-mo two signes, that ben y-lyke fer fro the heved of Capricorne, obeyen everÃch of hem til other. And for more declaracioun, lo here the figure. 30 29. TO KNOWE IUSTLY THE FOURE QUARTERS OF THE WORLD, AS EST, WEST, NORTH, AND SOWTH. [AD COGNOSCENDUM EVIDENTER QUATUOR PARTES MUNDI, SCILICET, ORIENTEM, AUSTRUM, AQUILONEM, ET OCCIDENTEM.] Take the altitude of thy sonne whan thee list, and note wel the quarter of the world in which the sonne is for the tyme by the azimutz. Turne thanne thyn Astrolabie, and set the degree of the sonne in the almikanteras of his altitude, on thilke side that the sonne stant, as is the manere in taking of houres; and ley thy 5 label on the degree of the sonne, and rikene how many degrees of the bordure ben by-twixe the lyne meridional and the point of thy label; and note wel that noumbre. Turne thanne a-gayn thyn Astrolabie, and set the point of thy gret rewle, ther thou takest thyne altitudes, up-on as many degrees in his bordure fro his 10 meridional as was the point of thy label fro the lyne meridional on the wombe-syde. Tak thanne thyn Astrolabie with bothe handes sadly and slely, and lat the sonne shyne thorow bothe holes of thy rewle; and sleyly, in thilke shyninge, lat thyn Astrolabie couch adoun evene up-on a smothe grond, and thanne wol the verrey 15 lyne meridional of thyn Astrolabie lye evene south, and the est lyne wole lye est, and the west lyne west, and north lyne north, so that thou werke softly and avisely in the couching; and thus hastow the 4 quarters of the firmament. And for the more declaracioun, lo here the figure. 20 30. TO KNOWE THE ALTITUDE OF PLANETES FRO THE WEY OF THE SONNE, WHETHER SO THEY BE NORTH OR SOUTH FRO THE FORSEIDE WEY. [AD COGNOSCENDUM ALTITUDINEM PLANETARUM A CURSU SOLIS, UTRUM SINT IN PARTE AUSTRALI VEL BOREALI A CURSU SUPRA DICTO.] Lok whan that a planete is in the lyne meridional, yif that hir altitude be of the same heyghte that is the degree of the sonne for that day, and than is the planete in the verrey wey of the sonne, and hath no latitude. And yif the altitude of the planete be heyere than the degree of the sonne, than is the planete north fro 5 the wey of the sonne swich a quantite of latitude as sheweth by thyn almikanteras. And yif the altitude of the planete be lasse than the degree of the sonne, thanne is the planete south fro the wey of the sonne swich a quantite of latitude as sheweth by thyn almikanteras. This is to seyn, fro the wey wher-as the sonne 10 wente thilke day, but nat from the wey of the sonne in every place of the zodiak. And for the more declaracioun, lo here the figure. 31. TO KNOWE THE SENITH OF THE ARYSING OF THE SONNE, THIS IS TO SEYN, THE PARTIE OF THE ORISONTE IN WHICH THAT THE SONNE ARYSETH. [AD COGNOSCENDUM SIGNUM DE ORTU SOLIS, SCILICET, ILLAM PARTEM ORIENTIS IN QUA ORITUR SOL.] Thou most first considere that the sonne aryseth nat al-wey verrey est, but some tyme by north the est, and som tyme by southe the est. Sothly, the sonne aryseth never-mo verrey est in oure orisonte, but he be in the heved of Aries or Libra. Now is thyn orisonte departed in 24 parties by thy azimutz, in significacion of 5 24 partiez of the world; al-be-it so that shipmen rikne thilke partiez in 32. Thanne is ther no more but waite in which azimut that thy sonne entreth at his arysing; and take ther the senith of the arysing of the sonne. The manere of the devisioun of thyn Astrolabie is this; I mene, as in this cas. First is it devided in 10 4 plages principalx with the lyne that goth from est to west, and than with a-nother lyne that goth fro south to north. Than is it devided in smale partiez of azimutz, as est, and est by southe, whereas is the firste azimut above the est lyne; and so forth, fro partie to partie, til that thou come agayn un-to the est lyne. 15 Thus maistow understond also the senith of any sterre, in which partie he ryseth, &c. And for the more declaracion, lo here the figure. 32. TO KNOWE IN WHICH PARTIE OF THE FIRMAMENT IS THE CONIUNCCIOUN. [AD COGNOSCENDUM IN QUA PARTE FIRMAMENTI SUNT CONIUNCCIONES SOLIS ET LUNE.] Considere the tyme of the coniunccion by thy kalender, as thus; lok how many houres thilke coniunccion is fro the midday of the day precedent, as sheweth by the canoun of thy kalender. Rikne thanne thilke nombre of houres in the bordure of thyn Astrolabie, as thou art wont to do in knowing of the houres of the day or of 5 the night; and ley thy label over the degree of the sonne; and thanne wol the point of thy label sitte up-on the hour of the coniunccion. Loke thanne in which azimut the degree of thy sonne sitteth, and in that partie of the firmament is the coniunccioun. And for the more declaracioun, lo here thy figure. 33. TO KNOWE THE SENITH OF THE ALTITUDE OF THE SONNE, &C. [AD COGNOSCENDUM SIGNA DE ALTITUDINE SOLIS.] This is no more to seyn but any tyme of the day tak the altitude of the sonne; and by the azimut in which he stondeth, maystou seen in which partie of the firmament he is. And in the same wyse maystou seen, by the night, of any sterre, whether the sterre sitte est or west or north, or any partie by-twene, after the 5 name of the azimut in which is the sterre. And for the more declaracioun, lo here the figure. 34. TO KNOWE SOTHLY THE DEGREE OF THE LONGITUDE OF THE MONE, OR OF ANY PLANETE THAT HATH NO LATITUDE FOR THE TYME FRO THE ECLIPTIK LYNE. [AD COGNOSCENDUM VERACITER GRADUM DE LONGITUDINE LUNE, VEL ALICUIUS PLANETE QUI NON HABET LONGITUDINEM PRO TEMPORE CAUSANTO LINEA ECLIPTICA.] Tak the altitude of the mone, and rikne thyn altitude up among thyne almikanteras on which syde that the mone stande; and set there a prikke. Tak thenne anon-right, up-on the mones syde, the altitude of any sterre fix which that thou knowest, and set his centre up-on his altitude among thyn almikanteras ther the sterre 5 is founde. Waite thanne which degree of the zodiak toucheth the prikke of the altitude of the mone, and tak ther the degree in which the mone standeth. This conclusioun is verrey soth, yif the sterres in thyn Astrolabie stonden after the trowthe; of comune, tretis of Astrolabie ne make non excepcioun whether the 10 mone have latitude, or non; ne on whether syde of the mone the altitude of the sterre fix be taken. And _nota_, that yif the mone shewe himself by light of day, than maystow wyrke this same conclusioun by the sonne, as wel as by the fix sterre. And for the more declaracioun, lo here thy figure. 15 35. THIS IS THE WORKINGE OF T |
