Robert Robinson of London (born c. 1590) was aged 69 in 1659. The handwriting of the manuscript identifies him as the compiler of 'Epigrams, Epitaphs, and other observations, divine, morall, charitable, satyricall, by Robert Robinson, London, 1660,' MS. Rawl. poet. 218, acquired with the Rawlinson bequest of 1756. The poems in the Rawlinson manuscript are indexed in Crum First-Line Index of English Poetry 1500-1800 in the Manuscripts of the Bodleian Library. Crum has recorded him also as the author of MS. Ashmole 826, fol. 110, which is 'copied in a secret character' (fol. 113). The handwriting of both these documents is indeed identical with that in the two Robinson compilations, and the 'secret character' is in fact a phonetic alphabet invented by Robinson. It appears in The Art of Pronuntiation by 'Robert Robinson, Londoner' (London, 1617), which identifies Robinson as the phonetician mentioned in Wikipedia. Very little else is known about Robert Robinson, and no literature up until now has connected the author of MS. Rawl. Poet. 218 with the Art of Pronuntiation. The improbable 43-year gap between the works made a link less likely, but Robinson's age being supplied by the present manuscript shows that the Art of Pronuntiation was an early work of the same man.
