This article explores the authorship of knowledge in the late seventeenth century, with a focus on Dr. Edward Browne's (1644-1708 contributions to the Royal Society and travel literature. An analysis of the manuscript sources and ensuing printed accounts of Browne's 1668-1669 European travels gives rise to three key conclusions: firstly, that correspondence sent to the Society's secretary, Henry Oldenburg (1619-1677), was not always unmediated and was at times edited by agents at home (in this case, Thomas Browne [1605-1682); secondly, that articles sent directly to Oldenburg by Society agents were also subject to editorial influences other than those of the primary author; and, finally, that the family was a key network of creation, both in articles printed in the Philosophical Transactions and in independent works. Throughout, it will become clear that Edward Browne's publications are not straightforwardly single authored: rather, they are the result of a wide variety of often obscured familial and social interactions.1 This poem is printed in Thomas Flatman's Poems and Songs (London, 1686). A version of this poem is preserved in the commonplace book of Elizabeth Lyttelton, Edward Browne's sister (Cambridge UL MS 8460, fol. 33). 2 Flatman was elected to the Royal Society four months after Edward on 30 April 1668, but Edward's journals and the Browne family letters suggest that the Brownes knew Flatman and his kin outside of the confines of the Royal Society: Edward's 1664 journal (BL Sloane MS 1906) mentions that he "had discourse with one Mr Flatman a chirugion" (fol. 46v); in the late 1670s, a postscript from Edward's sister Elizabeth Lyttelton to Edward's wife Henrietta in London asks her "to Put a frame & glass to the picture for Mr Flatman a very good one" (BL Sloane MS 1847, fol. 224v). Several other references to the Flatman family appear in the family letters of the 1670s.
