All above and around the monastery the hillside is spangled with scores of rude little oratories, mostly in a ruinous condition. These were erected sometimes by individual worshippers and sometimes by communities. The founder of such a chapel is thought to acquire singular merit; and it is held that, at his death, his chantry will be transported with him to paradise and serve as his heavenly mansion in the life to come. A lamp is lit in each of them by the temple priests at sundown, and at the same time other lamps are lit all over the temple, thus forming the necromantic illumination which so startled us the previous night. They only continue burning for about half an hour; but we chanced to arrive just in time to get the full effect. Within the main gateway of the monastery a flight of eight or ten steps leads down into a little sunken quadrangle; and the opposite side of this is occupied by the façade of the temple--a plain square wall of ashlar, unpierced by any window, but having a small arched doorway placed near the corner on the left. Many of the stones in this façade have queer cabalistic patterns, rudely incised in the surface so as to leave the device in low relief. The priests insist that these are all meaningless--mere bits of fanciful ornament introduced by the Christian builders:[45] but though it is likely enough that the original meaning of them is forgotten, it is manifestly absurd to pretend either that they never had any, or that none is attributed to them now. There are no Christian symbols among them; and the devices which recur most frequently represent a hatchet and a comb:[46] but the most ominous and the most prominent of all is the famous Snake, which is carved in relief on the door jamb, and which receives the peculiar attention of being kept carefully blacked. [Illustration: THE YEZIDI TEMPLE AT SHEIKH ADI] Three or four Yezidi worshippers were making their round of the quadrangle, prostrating themselves before certain niches and at several other recognized points. They devoutly kissed the threshold of the door, and several of the stones in the walls (by no means always the carved ones), but we did not see any of them pay particular homage to the snake. The priests were prepared for our visit, and were waiting at the door to receive us. They at once admitted us to the temple, first begging us to remove our shoes. This action is to be regarded as mere politeness, not as "bowing down in the house of Rimmon;" for it is customary to remove the shoes in Turkey, even when only entering a room.[47]
