Caswall’s father was Robert Clarke Caswall (Perpetual Curate of Yateley, and later Vicar of West Lavington, Wiltshire). His mother was a niece of Thomas Burgess, Bishop of St. David and later of Salisbury.
Caswall attended Chigwell Grammar School in Essex; Marlborough School; and Brasenose College, Oxford, where he graduated with honors in 1836.
Before leaving Oxford, he published, under the pseudonym of Scriblerus Redivivus, The Art of Pluck, in imitation of Aristotle, a satire on the ways of the careless college student.
In 1838, Caswall was ordained a deacon, and 1839 an Anglican priest. In 1840 he became Perpetual Curate at Stratford-sub-Castle near Salisbury.
By 1847, he had switched to Roman Catholicism and went to the Oratory of St. Philip Neri at Edgbaston, where he did most of his hymn work.
Caswall is best remembered as a translator of ancient hymns, though he also wrote original lyrics. His works include:
