The three remaining hexagons, up to 1878, contained fragments, and most interesting fragments, of older work, which evidently once formed part of the floor, where the High Altar now stands. To the left, looking east, was a delightful design representing the _Blind leading the Blind_. An old man is holding one end of a stick, while a young man, also blind, is grasping it at the other end. The older man is just stepping over a precipice into space. Below them is a delightful _putto_, holding in one hand a mirror, and a label with the word “_Notate_” upon it. This design we know to have been the work of Antonio Federighi in 1459; and for it he received 46 lire.[137] It was apparently ordered by the Rector, Benedetto di Biagio di Roberto, and completed during the Directorate of Cristofano Felice.[138] The middle design illustrates the _Parable of the Mote and the Beam_; and though it dates from 1374–5,[139] strangely enough is now in the best preservation of the three. The third design was a scene of a stately-looking bearded man, giving alms to a woman with a child in her arms. This is generally supposed to be that work of Domenico del Coro[140] which is referred to in a document dated 1433, as being placed by him in the choir (then under the cupola) _from the lectern downwards, in that place where they stand to sing_,[141] and for which he received 357 lire. It is impossible now to tell what was the original shape of these designs, or where they were placed. But to fit them into the hexagons, they were made into more or less complete triangles, the remainder of the space being filled up with fragments of old friezes, brought probably from the same place. In 1875, the fragments left of them, and of the four later _mandorle_, were removed to the Museum of the Opera, where they now are, and in 1878, all seven were replaced by others, completing the _Story of Elijah and Ahab_. The subjects chosen are, for the larger ones: 1. _Ahab mortally wounded._ No. 40. 2. _Elijah carried to Heaven in a Chariot of Fire._ No. 38. (Ill. XXVI.) 3. _Elijah predicts the manner of Ahab’s death._ No. 39. For the smaller ones: 1. _Elijah fed by Ravens._ No. 47. 2. _Elijah raises the widow’s son._ No. 50. 3. _Elijah asks bread of the widow._ No. 49. 4. _Elijah anoints Jehu, King of Israel._ No. 48.
