[3][4][5] About 1790 Seyer succeeded John Jones at the Royal Fort school, where for ten years Andrew Crosse was among his scholars, who found him narrow-minded and unjust.
He died at his house in Berkeley Square, Bristol[6] on 25 August 1831 [1] aged 73, and was buried at St Mary's churchyard, Shirehampton.
Seyer was refused access to the originals in the Bristol council-house, and based his text on a late manuscript in the Bodleian Library (Rawlinson 247); he used a translation published in 1736.
[1] In 1821–3 appeared Seyer's Memoirs, Historical and Topographical, of Bristol and its Neighbourhood,[8] with plates by Edward Blore and others (2 vols.).
[1] Seyer published also:[1] He translated into English verse the Latin poem of Marco Girolamo Vida on chess.
