The earliest authorities testify as usual to the undainty acquisitiveness of the Clergy, making profit alike of the weakness and the wealth, the crimes and the penitence of all around them. Augmenting and prospering by Gifts—such as those of the Odaller of Airland to the Crosskirk of Stenness, of David of Rendall to St. Ninian, or of Guidbrand of Quendal to the Vicar of Evie, for “a mass ilk Friday;” by Confiscations—as of Baddi’s Lands for bloodshed in the Kirkyard; by perpetuation of all liferent Donations; by pretended Excambion, retaining their own land and seizing the promised equivalent; by withholding their own Skatts and embezzling others, and by the numberless oppressions of lawless strength against weak neighbours, the Bishops advanced in wealth and power. In the quaint language of Bishop Graham, “the old Bishopric of Orkney became a greate thing, and lay _sparsim_ throughout the haill parochines of Orkney and Zetland. Besyde his lands, he hade the teyndis of achtene kirks; his lands grew daily as adulteries and incests increased in the countrey,” till they were “estimat at the third part of the COUNTREYIS of old.” How or when the Bishops were permitted to Tithe the lands and labour of the Islands is uncertain; probably the building of Magnus Kirk, the Primus Episcopus, and this impost were connected and coincident (1136); but its rigorous exaction and arbitrary increase were probably too recent for popular patience, when (in 1222) Bishop Adam was burned to death for doubling the customary payment. Certain Skatts were probably granted among the earliest provisions for religious uses, but the indiscriminate appropriation of those of Church-lands and others probably commenced when the Scottish Bishop, Thomas Tulloch, combined the powers and opportunities of Bishop, Governor and Collector of Royal Revenues, during the non-investiture of Earl William (1422–34). With possessions so extensive, a jurisdiction over their own lands almost unlimited, and an influence dreaded by all in this world, as all-prevailing in that which is to come, the Bishop could cope with the waning power of the Jarl as easily as other Prelates of the Scandinavian Church could defy the Crown. Safe in his Palace of KIRKWALL or his stately Castle of NOLTLAND (his _Land of Leisure_, his Episcopal _Buen Retiro_ or _Sans Souci_), he was within his own domain as powerful for good or evil as the Crown or its Donatary, but Orkney never tasted the full bitterness of oppression, till the powers of both were united in such hands as those of Bishop Thomas, or his kinsman and successor William Tulloch, who filled the See at the date of the Impignoration, and was rewarded for his supple usefulness by a favourable Tack of the Earldom and Royal revenues. It was fatal to the interests and independence of Orkney, that, at such a crisis of transition, the power to interpret and fix the existing and future rights of parties should have been intrusted to such an arbiter.
