    Description
    This 'Draft of a Concerted Tube at Florence' depicts a telescope Robert Southwell encountered while in Italy. It is referred to in a letter he wrote to Robert Boyle (BL 6, fols 54-5. Fol/2). This image is now amongst the papers collected by Robert Southwell.

    A more worked up but nearly identical version of this image survives among Robert Hooke's papers at Cl.P/20/61, and is endorsed 'Figure of a way to manage Long Telescopes. II. 31. N[ot] P[rinted]'.
    Object history
    This manuscript was sold at Sotheby's in June 1893 (Phillips sale) and acquired by the Royal Society from a purchaser of that lot. Some of the material is signed by Robin Bacon, who was also Robert Boyle's scribe (see William Poole, 'Sir Robert Southwell's Dialogue on Thomas Burnet's Theory of the Earth: "C & S Discourse of Mr Burnett's Theory of the Earth" (1684): Contexts and an Edition', The Seventeenth Century, 23 (2008), 72-104).
