His poems, published in 1665 (reprinted and edited by John Churton Collins in 1881), show him in general a faithful disciple of Donne. His satires are poor, but a few of his lyrical verses show power of reflection and true inspiration, while his use of the metre afterwards employed by Tennyson in his "In Memoriam" is particularly happy and effective. His Neo-Latin poems are evidence of his scholarship. Three of these had appeared together with the "De causis errorum" in 1645.
