Thomas Chillenden

Thomas Chillenden (died 15 August 1411) was Prior of Christ Church Priory, Canterbury from 1391 to 1410. Under him, from 1391 to 1400, the Cathedral-Priory church's nave was rebuilt in the Perpendicular style of English Gothic architecture.

His family (and hence its surname) probably originated in the Kentish village of Chillenden, though his parents are unknown. After becoming a monk at Christ Church Priory, he studied for a bachelorship in canon law at Canterbury College, Oxford from 1365 to 1378, before going to Rome to study the same subject at the papal curia. There he became Doctor of Canon Law, in 1383 or earlier, put together an index to the fourth book of the Decretals of Gregory IX (Repertorium quarti libri decretalium), wrote a commentary to the Regulae juris (Longleat, MS 35, fols. 187–206), and lectured on the fourth book of the Clementines (‘Reportata on the Clementines’). In 1383 the University of Oxford was involved in a dispute with St Frideswide's Priory, and Chillenden served as the former's proctor.

Chillenden's election as prior came after some time as one of the Priory's treasurers. As prior, Chillenden also tried to hold onto partial control of the monasteries's finances, subsuming his role of treasurer into his office of prior. All the monastery's income from, for example, its oblations and manors thus passed through his office, with him allocating a sufficient allowance to meet the expenditure of each obedientary (e.g. cellarer, sacrist). In addition, with the monastery - in the wake of the Black Death - veering between leasing out and directly managing its East Kent manors and leasing them out, he ceased direct management (then true of many, but not all, its manors) and reformed the leasing system, with rents being paid in fixed quantities of stock and grain rather than in money. However, he did not bring so sudden an end to the priory's estates being directly managed as RAL Smith maintains. Whilst Chillenden was prior, twenty-four books on canon law and another eleven on civil law were added to the monastery library. One of these was probably the Repertorium sexti libri decretalium - it was previously attributed to Chillenden himself, but was actually written by a monk called John.
