Editing Constantijn Huygens (section)

===Correspondence===
Aside from his ''membership'' in the Muiderkring (which was not as formerly supposed, an official club), at the start of the 1630s he was also in touch with [[René Descartes]],<ref name=":0">Sanford Budick, “Descartes’s Cogito, Kant’s Sublime, and Rembrandt’s Philosophers: Cultural Transmission as Occasion for Freedom,” from A Journal of Literary History (Washington: Modern Language Quarterly, 1997), 38.</ref> with [[Rembrandt]],<ref name=":0" /> and the painter [[Jan Lievens]]. He became friends with [[John Donne]],<ref name=EB1911/> and translated his poems into Dutch. He was unable to write poetry for months because of his anguish over his wife's death, but eventually he composed, inspired by [[Petrarch]], the sonnet ''Op de dood van Sterre'' (On the death of Sterre), which was well received. He added the poem to his ''Dagh-werck'', which he left unfinished: the day he has described has not ended yet, but his Sterre is already dead. After sending the unfinished work to different friends for approval, he eventually published it in 1658 as part of his ''Koren-bloemen''.

Huygens also corresponded with [[Margaret Croft]] and [[Elizabeth Dudley, Countess of Löwenstein]], ladies in waiting to [[Elizabeth Stuart, Queen of Bohemia]], and [[Mary Woodhouse]], a friend made in London in 1622.<ref>Lisa Jardine, [https://www.ucl.ac.uk/ucl-press/browse-books/temptation-in-the-archives ''Temptation in the Archives'' (UCL: London, 2015)], pp. 1-17.</ref>
