In 1274 the council of Lyons imposed a tax of a tenth part of all church revenues during the six following years for the relief of the Holy Land.
In Scotland, Pope Gregory X, entrusted the collection of this tax to Master Boiamund (better known as Bagimund) de Vitia, a canon of Asti, whose roll of valuation formed the basis of ecclesiastical taxation for some centuries.
The clergy of Scotland objected to this innovation, and, having held a council at Perth in August 1275, prevailed upon Boiamund to return to Rome for the purpose of persuading the pope to accept the older method of taxation.
[1] A fragment of Bagimond's Roll in something very like its original form is preserved at Durham, and has been printed by James Raine in his Priory of Coldingham (Publications of the Surtees Society, vol.
The fragment should therefore be regarded as supplementary to the Taxatio Ecclesiastics Angliae et Walliae printed by the Record Commissioners in 1802.
