William Browne had a high opinion of his friend Brooke's poetic capacity. He eulogises him in 'Britannia's Pastorals,' book ii. song 2. In the fifth eclogue of the 'Shepheard's Pipe,' 1615, which is inscribed to Brooke, Browne urges him to attempt more ambitious poetry than the pastorals which he had already completed. Brooke's works are:
- An elegy on the death of Prince Henry, published with another elegy by William Browne in a volume entitled 'Two Elegies consecrated to the neverdying Memorie of the most worthily admyred, most hartily loved and generally bewailed prince, Henry, Prince of Wales,' London, 1613.
- An eclogue appended to William Browne's 'Shepheard's Pipe,' London, 1614.
- 'The Ghost of Richard the Third. Expressing himselfe in these three parts: 1, His Character; 2, His Legend; 3, His Tragedie,' London, 1614. The unique copy in the Bodleian Library was reprinted by John Payne Collier for the Shakespeare Society in 1844, and by Alexander Balloch Grosart in 1872. It is dedicated to Sir John Crompton and his wife Frances. Mr. Rodd, the bookseller, first attributed this work to Brooke at the beginning of the 19th century. The only direct clue lies in 'C. B.,' the signature of the dedication. George Chapman, William Browne, 'Fr. Dyune Int. Temp.,' George Wither, Robert Daborne, and Ben Jonson contribute commendatory verses.
- 'Epithalamium...a nuptiall song applied to the ceremonies of marriage,' which appears at the close of 'England's Helicon,' 1614.
- 'A Funerall Poem consecrated to the Memorie of that ever honoured President of Soldyership, Sr Arthure Chichester . . . written by Christopher Brooke, gent.,' in 1624. This poem, to which Wither contributes commendatory verses, was printed for the first time by Grosart in 1872. The manuscript had been in the possession of Bindley, Heber, and Corser. Corser printed selections in his 'Collectanea,' and Haslewood described it in the 'British Bibliographer,' ii. 235.
Brooke also contributed verses to Michael Drayton's 'Legend of the Great Cromwell,' 1607; to Thomas Coriat's 'Odcombian Banquet,' 1611; to Lichfield's 'First Set of Madrigals,' 1614 (two pieces, one to the Lady Cheyney and another to the author); and to Browne's 'Britannia's Pastorals,' 1625. He also wrote (20 December 1597) inscriptions for the tombs of Elizabeth, wife of Charles Croft, and of the wife of Thomas Crompton.
