many other later Writers, who aſſented unto
their Hypotheſis; ſo Foach. Rhelicus, David
Origanus Lansbergius, Guil. Gilbert, and (iſ I

French, all who affirm’d our Earth to be one
of the Planets, and the Sun to be the Centre of
all, about which the Heavenly Bodies did

at firſt, yet is it likely enough to be true, nor
is there any Maxim or Obſervation in Op-
ticks (ſaith Pena) that can diſprove it.

(as it is according to them) then why may not
another of the Planets be an Earth.

Propoſition. Before I proceed farther, ’tis
requiſite that I inform the Reader, what Me-
thod I ſhall follow in the proving of this chief
Aſſertion, that there is a World in the Moon.

The Order by which I ſhall be guided, will

thoſe things which are Extrinſical to it, as the
Seaſons, Meteors, and Inhabitants.
