Plate XXXI from Write's book (see description below).
From the 9th letter of Thomas Wright's ``An Original Theory of the Universe'' (1750) Plate XXXI, about which he writes: ``. . . that as the visible Creation is supposed to be full of sidereal Systems and planetary Worlds, so on, in like similar Manner, the endless Immensity is an unlimited Plenum of Creations not unlike the known Universe. See Plate XXXI. which you may if you please, call a partial View of Immensity, or without much Impropriety perhaps, a finite View of Infinity ... That this in all probability may be the real Case, is in some Degree made evident by the many cloudy Spots, just perceivable by us, as far without our starry Regions, in which tho' visibly luminous Spaces no one Star or particular constituent Body can possibly be distinguished; those in all likelyhood may be external Creation, bordering upon the known one, too remote for even our Telescopes to reach.''
