and speaking of 'twain' and 'welkin'...

Of that house A. Horne is lord. Seventy beds keeps he there teeming mothers are wont that they lie for to thole and bring forth bairns hale so God's angel to Mary quoth. Watchers they there walk, white sisters in ward sleepless. Smarts they still sickness soothing: in twelve moons thrice an hundred. Truest bedthanes they twain are, for Horne holding wariest ward.

In ward wary the watcher hearing come that man mild-hearted eft rising with swire ywimpled to him her gate wide undid. Lo, levin leaping lightens in eyeblink Ireland's westward welkin!
