Some time in or after 1617 appeared his "Third and Fourth Booke of Ayres". In 1618 appeared the airs that were sung and played at Brougham Castle on the occasion of the King's entertainment there, the music by George Mason and John Earsden, while the words were almost certainly by Campion. In 1619, he published his "Epigrammatum Libri II. Umbra Elegiarum liber unus", a reprint of his 1595 collection with considerable omissions, additions (in the form of another book of epigrams) and corrections.
