There are a number of interesting monuments, including the black Delabole slate memorial to Richard Durant, his wives and twenty children, carved in low relief.

Thomas Vyvyan (or Vivian), the penultimate prior of Bodmin Priory, was consecrated bishop of the titular see of Megara in Greece in 1517.

At Rialton, chief manor of the priory, Prior Vyvyan, a Cornishman, had already built c. 1510 a good residence for himself; parts of this structure are still extant.

[7] Unusually, the three, late 15th century misericords have at some point been taken from their original stalls (which may not even have been in St Petroc's) and fitted into the lectern.

Around 1155, Hugh Candidus claimed that Bodmin was the resting place of Credan, Medan and Dachuna, whom he identified as associates of Petroc.

The foundation of the monastery is also attributed to King Athelstan though it probably existed before his time, and was destroyed in a Danish raid in 981 AD.

The holdings were mainly in the hundreds of Trigg and Pydar and at the time of Domesday the monastery still held 18 manors, including Bodmin, Padstow and Rialton.

Robert, Count of Mortain held from the monastery the manors of Tywarnhayle, Halwyn, Callestick, Cargoll, Treloy, St Enoder and Bossiney; lands in Tregona, Trevornick, Trenhale, Tolcarne, Tremore, Lancarffe and Treninnick were taken from the monastery by Count Robert and in 1086 they were held by his tenants.

After St Petroc's relics were stolen in 1177 they were recovered and returned to Prior Roger (the ivory casket in which they were kept has survived to the present day).

[14] His works include The Cornwall Register: containing collections relative to the past and present state of the 209 parishes, forming the county, archdeaconry, parliamentary divisions, and poor law unions of Cornwall; to which is added a brief view of the adjoining towns and parishes in Devon, from Hartland to Plymouth (Bodmin: printed by Liddell & Son, 1847); which was preceded by The Bodmin Register: containing collections relative to the past and present state of the parish of Bodmin : and also, a statistical view of the twenty-eight parishes within a circle of eight miles round Bodmin church : together with many particulars and statistical tables concerning the county, archdeaconry, parliamentary districts, and poor law unions of Cornwall: with an appendix on the diocese of Exeter &c. (Bodmin: printed by Liddell & Son, 1838).
