That is, When, in long process of time, the Silt and Sands shall so choak and shallow the Sea in and about it. And this hath considerably come to pass within these fourscore years; and is like to encrease from several causes, especially by the turning of the River Brenta, as the learned Castelli hath declared.
When Nova Zembla shall be no stay
Unto those who pass to or from Cathay.
That is, When ever that often sought for Northeast passage unto China and Japan shall be discovered; the hindrance whereof was imputed to Nova Zembla; for this was conceived to be an excursion of Land shooting out directly, and so far Northward into the Sea that it discouraged from all Navigation about it. And therefore Adventurers took in at the Southern part at a strait by Waygatz next the Tartarian Shore: and, sailing forward they found that Sea frozen and full of Ice, and so gave over the attempt. But of late years, by the diligent enquiry of some Moscovites, a better discovery is made of these parts, and a Map or Chart made of them. Thereby Nova Zembla is found to be no Island extending very far Northward; but, winding Eastward, it joineth to the Tartarian Continent, and so makes a Peninsula: and the Sea between it which they entred at Waygatz, is found to be but a large Bay, apt to be frozen by reason of the great River of Oby, and other fresh Waters, entring into it: whereas the main Sea doth not freez upon the North of Zembla except near unto Shores; so that if the Moscovites were skilfull Navigatours they might, with less difficulties, discover this passage unto China: but however the English, Dutch and Danes are now like to attempt it again.
But this is Conjecture, and not Prophecy: and so (I know) you will take it. I am,
Sir, etc.
