Salusbury was a poet and patron of literature. Several works were dedicated to him. In 1595 Henry Perry dedicated his book of Welsh grammar
Egluryn Ffraethineb to Salusbury.
Sinetes Passions (1597) a collection of verse by
Robert Parry, was also dedicated to Salusbury. The most important work linked to Salusbury is
Robert Chester's book ''Love's Martyr'', which is dedicated to Sir John. Both Parry and Chester seem to have been local Denbighshire writers who formed part of Salusbury's own circle. Salusbury's own poetry may have been published in Parry's collection in the section entitled the "patron's pathetical posies", though this has been disputed. These include a complex symbolic poem addressed to his sister-in-law, Dorothy Halsall. Other sonnets and love lyrics of his exist in manuscripts. Chester was probably Salusbury's chaplain or secretary. His long and extremely obscure allegory about a phoenix and turtledove has led to several conflicting interpretations. The most common are that it symbolises either the love of John and Ursula, or alternatively the idealised relationship between Sir John and Queen Elizabeth. Chester's poem contains a series of "Cantos" at the end of the allegory.
William Empson argues that the "Cantos" are by Salusbury, as they are similar in style to those appended to Robert Parry's book, displaying Salusbury's "very recognisable facility and ingenuity".
E. A. J. Honigmann argues that Salusbury had a fascination with "mystical verse" which contained obscure acrostic puzzles, and that his patronage explains the unique metaphysical symbolism of Parry's, Chester's and his own verse. Salusbury also seems to have been acquainted with
Ben Jonson, who may have been the person responsible for organising a group of important poets to contribute verses to supplement Chester's poems. Among these were Jonson himself,
John Marston,
George Chapman and
William Shakespeare, who contributed
The Phoenix and the Turtle. These poems share the imagery of ''Love's Martyr'' and Salusbury's typical elusive and complex allegorising. ==References==
