One argument whereby I shall manifest this truth, may be taken from those new Starres which have appeared in divers ages of the world, and by their parallax have beene discerned to have been above the _M_oone, such as was that in _Cassiopeia_, that in _Sagittarius_, with many others betwixt the Planets. _Hipparchus_ in his time tooke especiall notice of such as these,[1] and therefore fancied out such constellations in which to place the Starres, shewing how many there were in every asterisme, that so afterwards posterity might know, whether there were any new Starre produced or any old one missing. Now the nature of these Comets may probably manifest, that in this other world there are other meteors also; for these in all likelihood are nothing else but such evaporations caused by the Sunne, from the bodies of the Planets. I shall prove this by shewing the improbabilities and inconveniences of any other opinion. [Sidenote 1: _Plin. nat. hist. l. 2. c. 26._] For the better pursuite of this ’tis in the first place requisite that I deale with our chiefe adversary, _Cæsar la Galla_, who doth most directly oppose that truth which is here to bee proved. Hee endeavouring to confirme the incorruptibility of the Heavens, and being there to satisfie the argument which is taken from these comets, He answers it thus: _Aut argumentum desumptum ex paralaxi non est efficax, aut si est efficax, eorum instrumentorum usum decipere, vel ratione astri vel medii, vel distantiæ, aut ergo erat in suprema parte aeris, aut si in cœlo, tum forsan factum erat ex reflectione radiorum Saturni & Jovis, qui tunc in conjunctione fuerant._ “Either the argument from the paralax is not efficacious, or if it be, yet the use of the instruments might deceive either in regard of the starre or the _medium_, or the distance, and so this comet might be in the upper regions of the aire, or if it were in the heavens, there it might be produced by the reflexion of the rayes from _Saturne_ and _Jupiter_, who were then in conjunction.” You see what shifts hee is driven to, how he runnes up and downe to many starting holes, that hee may find some shelter, and in stead of the strength of reason, he answers with a multitude of words, thinking (as the Proverbe is) that hee may use haile, when hee hath no thunder, _Nihil turpius_ (saith [1]*_Seneca_) _dubio est incerto, pedem modo referente, modo producente._ “What can there bee more unseemely in one that should be a faire disputant, then to be now here, now there, and so uncertaine, that one cannot tell where to find him.”
