The change from the “Treasury” to the “Exchequer” was, I hold, a gradual process. Careful study of the annual revenues bestowed by our sovereigns on the foreign houses of Tiron, Fontevrault, and Cluny[174] proves clearly how insensibly the “Treasury at Winchester” was superseded by the “Exchequer at London” as the place of payment. This is especially the case with Tiron, where Henry I.’s original grant, made about the middle of his reign, provides for payment “de thesauro meo, in festo Sancti Michaelis, _Wintonie_.”[175] Under Richard I. this becomes payable “at Michaelmas from his exchequer at London.”[176] Documents between the two show us intermediate stages. Precisely the same gradual process is seen in the parallel development of the chamberlainship of the “Exchequer” from that of the “Treasury.” Just as Henry II., shortly before his accession, confirmed the grant to Tiron as “de thesauro Wintonie,”[177] so he restored to William Mauduit, at about the same time, “camerariam meam _thesauri_,” which office was held by his descendants as a chamberlainship of the _Exchequer_. The ‘Dialogus’ shows us the Treasurer and the two chamberlains of the Exchequer as the three inseparable Treasury officers. Domesday connects the first with Winchester by showing us Henry “thesaurarius” as a tenant-in-chief in Hampshire. I propose to show that it also connects one of the chamberlains with that county. In that same invaluable but unprinted charter of which I have spoken above, which was granted at Leicester (1153) to William Mauduit, Duke Henry says: Insuper etiam reddidi eidem camerariam meam thesauri cum liberatione[178] et cum omnibus pertinentibus, castellum scilicet de Porcestra ut supradiximus, et omnes terras ad predictum camerariam et ad predictum castellum pertinentes, sive sint in Anglia sive Normannia, sicut pater suus illam camerariam cum pertinentibus melius habuit et sicut Robertus Maledoctus frater suus eam habebat die quo vivus fuit et mortuus. This carries back the ‘cameraria thesauri’ (‘_illam_ camerariam’) to the Domesday tenant, whose son Robert occurs in the earlier Winchester Survey, and, though dead in 1130, is mentioned on the Roll of that year (p. 37), in connection with the Treasury in Normandy.
