312. 'Is there no choice as to when to fix the voyage?' The favourable moment for commencing a voyage was one of the points on which it was considered desirable to have an astrologer's opinion. Travelling, at that time, was a serious matter. Yet this was only one of the many undertakings which required, as was thought, to be begun at a favourable moment. Whole books were written on 'elections,' i. e. favourable times for commencing operations of all kinds. Chaucer was thinking, in particular, of the following passage, which is written in the margins of the Ellesmere and Hengwrt MSS.: 'Omnes concordati sunt quod elecciones sint debiles nisi in diuitibus: habent enim isti, licet debilitentur eorum elecciones, radicem, i. [_id est_] natiuitates eorum, que confortat omnem planetam debilem in itinere.' The sense of which is--'For all are agreed, that "elections" are weak, except in the case of the rich; for these, although their elections be weakened, have a "root" of their own, that is to say, their nativities (_or_ horoscopes); which root strengthens every planet that is of weak influence with respect to a journey.' This is extracted, says Tyrwhitt, from a Liber Electionum by a certain Zael; see MS. Harl. 80; MS. Bodley 1648. This is a very fair example of the jargon to be found in old books on astrology. The old astrologers used to alter their predictions almost at pleasure, by stating that their results depended on several causes, which partly counteracted one another; an arrangement of which the convenience is obvious. Thus, if the aspect of the planets at the time inquired about appeared to be adverse to a journey, it might still be the case (they said) that such evil aspect might be overcome by the fortunate aspect of the inquirer's horoscope; or, conversely, an ill aspect in the horoscope could be counteracted by a fit election of a time for action. A rich man would probably be fitted with a fortunate [152] horoscope, or else why should he buy one? Such horoscope depended on the aspect of the heavens at the time of birth or 'nativity,' and, in particular, upon the 'ascendent' at that time; i. e. upon the planets lying nearest to the point of the zodiac which happened, at that moment, to be _ascending_, i. e. just appearing above the horizon. So Chaucer, in his Treatise on the Astrolabe, pt. ii. § 4, (vol. iii. 191), explains the matter, saying--'The assendent sothly, as wel in alle nativitez as in questiouns and _elecciouns of tymes_, is a thing which that thise Astrologiens gretly observen'; &c. The curious reader may find much more to the same effect in the same Treatise, with directions to 'make roots' in pt. ii. § 44. The curious may further consult the Epitome Astrologiae of Johannes Hispalensis. The whole of Book iv. of that work is 'De Electionibus,' and the title of cap. xv. is 'Pro Itinere.'
