Nevertheless by the time Donne wrote his hymn the sea to the south of Terra del Fuego had recently been discovered. He is using the language of a slightly earlier date, of his own youth, when travels and far countries were much in his imagination. In 1617 George, Lord Carew, writing to Sir Thomas Roe, Ambassador at the Court of the Mogul, says: 'The Hollanders have discovered to the southward of the Strayghts of Magellen an open sea and free passage to the south sea.' Letters of George, Lord Carew to Sir Thomas Roe, Camden Society, 1860. For the 'Straight of Anyan' compare also:
This makes the foisting traveller to sweare,
And face out many a lie within the yeere.
And if he have beene an howre or two aboarde
To spew a little gall: then by the Lord,
He hath beene in both th'Indias, East and West,
Talks of Guiana, China, and the rest,
The straights of Gibraltare, and Ænian
Are but hard by; no, nor the Magellane:
Mandeville, Candish, sea-experienst Drake
