“In a comparatively level spot, closely surrounded by rocks, there is a low, rough, oval-shaped chapel (Fig. 39), internally measuring no more than 14 feet in length [8 feet wide at the middle, and 6 feet 4 inches at the ends],[74] the extreme antiquity of which there seems no reason to question. On the outside (Fig. 40) the roof of this primitive cell is of curved form, but inside the rude vaulting, which may be said to commence almost from the ground, finishes somewhat short of the summit in so many heavy slabs laid horizontally across. Externally the building is a little dilapidated at both ends, and so is the roof; but within it is quite perfect, and seemingly noways altered from its original state. Entrance to it is by a low and very narrow flat-topped doorway, with sloping jambs [3 feet 5 inches in [Illustration: FIG. 40.--Teampull Sula Sgeir.] height, 16 inches wide at top and 22 inches at bottom][74] in the south wall. On its east is a small squared recess, and there is another recess of the same kind in the west wall. The only window is a small one, of squared form [2 feet 8 inches in length], in the east end, under which is an altar, flanked by slabs, set on edge, and raised on a slightly elevated dais, as is shown on the annexed plan.”[75] FLANNAIN ISLES, OR SEVEN HUNTERS. SEVERAL WILD UNAPPROACHABLE ISLANDS LYING TO THE WESTWARDS OF LEWIS. Eilean Mòr, the largest of the group (about one-third of a mile in extent), has precipitous sides and a flat grassy plain on the top, which slopes to the south-west. [Illustration: FIG. 41.--Teampull Beannachadh. West End.] “The chapel of St. Flann, or Teampull Beannachadh (blessing) as it is commonly called ... stands nakedly about the middle of the slope, unenclosed and with no indications of having ever been surrounded by a burial-ground. (Figs. 41, 42.) It is a very primitive looking thing, composed of rough stones joggled compactly together without lime. The form is a squared oblong, but not strictly regular, the external lengths of the north and south walls being respectively 11 feet 11 inches and 12 feet 2 inches, the east and west walls, 10 feet 3 inches and 9 feet 2 inches respectively; [within the dimensions are--length 7 feet 3 inches; width, 4 feet 5 inches.][76] The walls vary in thickness from 2 feet 5 inches to 2 feet 11 inches, taper a little, and are covered with a stone roof internally flat, but following the obtusely pointed or cradle form of the gables on the outside. Externally, [Illustration: FIG. 42.--Teampull Beannachadh. East End.] the total height of the cell is only 8 feet 6 inches; internally, 5 feet 9 inches. A narrow squared aperture, scarcely 3 feet in height [1 foot 10 inches in width],[77] in the west end, is at once doorway and window, besides it there being no opening of any kind in the building.”[78] III.
