While preparing the Greek aphorisms he also worked on an edition of the "Poetæ minores Græci", based upon those of Henry Stephen (1566) and Jean Crispin (1600), with observations of his own on Hesiod. The book was published at Cambridge in 1635, with a dedication to Archbishop Laud, and subsequent editions appeared in 1652, 1661, 1671, 1677, 1684, 1700, and 1712. He published at Cambridge in 1631 Greek verses at the end of William Buckley's "Arithmetica Memorativa", and in 1635 verses in "Carmen Natalitium", and in "Genethliacum Academiæ". Winterton made his will on 25 August 1636, leaving bequests to his father, mother, brothers John, Henry, and William, and sisters Mary, Barbara, Fenton, and Ruth. To his brother John, who was a student of medicine at Christ's College, Cambridge and who wrote verses in ‘Carmen Natalitium,’ he gave the medical works of Daniel Sennertus in six volumes and of Martin Rulandus, and the surgery of William Clowes the younger, with his anatomy instruments.
