To Sir Thomas Lucy, grandson of the Sir Thomas immortalized as _Justice
Shallow_. Lucy was a friend of the Herberts, with whom Donne afterward
became intimate, and a man of no mean intellectual power.
Donne gave up his house in Mitcham, where this letter was written, in 1610
and never returned to it. Lucy went abroad with Sir Edward Herbert in
1608. This letter may belong to the autumn of 1607.
