Parker with respect to the stone vault and the double wall-arcade, but have considered that the intention was from the beginning to construct them as they now are seen. In addition to the work still existing, St. Hugh united the north and south limbs of his eastern transept by a most remarkable apse. To learn the character of this work we must again trace the foundations beneath the floor. In the year 1791 the choir and presbytery were repaved, when parts of the foundations of Hugh's apse were discovered. The Rev. John Carter, who was master of the Lincoln Grammar School at the time, made a sketch and notes of the discovery. The drawing was lithographed and published in the "Associated Societies' Reports" for 1857. Far more important revelations were made in 1886, when it became necessary to take up a portion of the pavement at the south-west end of the south aisle of the presbytery. Precentor Venables had long desired an opportunity of investigating on this spot, and readily gave permission to have the pavement removed, at the same time instructing that an effort should be made to find the foundations of the destroyed apse. The work began in November, and in consequence of the discovery of part of the south wall, it was decided to systematically proceed with the investigations. The result was highly satisfactory. A detailed account was published in the _Archæological Journal_ for 1887, vol. xliv. From this it appears that the apse was almost in the form of a triangle, of which the apex was cut off by a short wall, so as to form a half-hexagon with two long sides, and a shorter one at the end. In each of the longer sides were two chapels, the walls of one in the form of three-fourths of a circle, having a diameter of 18 feet, and the other, a smaller one, having straight side walls and rounded ends; a half-hexagonal chapel with an internal diameter of 23 feet occupied the centre of the apse at the extreme east. It was at first thought that the smaller chapels at the sides might indicate stair-turrets, which would occupy a similar position to those in the apse at Peterborough, but no trace of the foundations of a newel could be found in either case. The apse extended to the second bay of the present Angel Choir, 48 feet short of its eastern end. Throughout almost the whole of the investigations, only the rude concrete foundations were found remaining, their upper surface being about 16 or 17 inches below the existing pavement; in parts, however, fragments of the walling were also discovered.
