feelingless

Accustomed by the strictest and most rigid training, to obey as familiars, the will of their superiors without question--to be mere mindless and feelingless tools, to whom death itself was awarded, if by word or hint, or even sign, they dared evince themselves to be as other men--he had, at the command of the Grand Inquisitor, deeply drugged Senor Stanley's evening draught, and, while under its potent influence, had purloined his sword; waylaid Don Ferdinand in the Calle Soledad, effectually done the deed, and--aware that it would be many hours ere the English Senor could arouse himself from the stupifying effects of the draught--had intended returning to his chamber still more effectually to throw on him the suspicion of the murder.

1851, Grace Aguilar, The Vale of Cedars

I will quickly fly from thee for ever, Thou hated land, where everything so proudly Upbraids me for my weakness--for my fetters: Where I, pursu'd by pains of hopeless passion, The live-long nights among deaf rocks do wander-- Whose echoes sport with Balder's lamentations, Each cold, each feelingless, as Nanna's bosom, The fair, unpitying savage!

1889, George Borrow, The Death of Balder
