The elder son of Gregory Viccars of Treswell in Nottinghamshire, he was baptised there on 30 October 1604; his sister Helen was the wife of the dramatist William Sampson.
[2][3] In 1627 Viccars became vicar of St Mary's Church, Stamford; but in 1628 some of the congregation accused him of heresy.
[2] Viccars is mentioned in connection with Brian Walton's London Polyglot in 1652, but not subsequently.
[1] Viccars' major work is a multilingual psalm commentary, Decapla in Psalmos: sive Commentarius ex decem Linguis (London, 1639) in Hebrew, Arabic, Syriac, Rabbinic, Chaldean, Greek, Latin, Italian, Spanish, and French.
[5] These works, which were previously attributed to the presbyterian poet and chronicler John Vicars, propagated Viccars' royalist, Laudian views in defence of liturgical tradition as the English Civil War began.
