Description
A figure in John Collins's 'Memorandum', drafted as the basis of a letter for Henry Oldenburg to send to Renatus Franciscus Slusius, which was indeed sent on 4 March 1672.
The diagram illustrates Isaac Barrow's theorem regarding a cycloid, explained by Collins as follows: 'If any two Curves as AB, CD be alternly placed about the same Axis AC, the greatest common Ordinate is that whose touch lines EG and FH are parallel And the greatest rectangle EIF is that, where the Segments of the Axis produced (as CG, AH) cutt off by the touch lines are equall.'
The diagram in Oldenburg's letter to Slusius can be found at EL/O2/79/003 and in its copy at LBO/5/179.
