The angels sculptured in stone, and mostly carrying scrolls, fill the triforium spandrels in groups of three, five groups on either side. They are probably not all by the master’s hand. The Virgin and Child in the south-west bay and the angel with drawn sword in the north-west seem finer than the rest. The stone inscribed in Lombardic letters “Cantate Hic,” marks the place for chanting the Litany; this is chanted by two lay clerks. There are nine of these, one being vestry clerk; also four choristers in black gowns with white facings (a reminiscence of the earliest dress for the Lincoln choir, and a unique costume in England), eight Burghersh choristers or “Chanters” (lineal descendants of the Burghersh chantry of St. Catherine with its separate band of choristers), and some supernumerary boys and men. There are four canons residentiary, viz., the sub-dean, chancellor, precentor, and Archdeacon of Lincoln, and fifty-three prebendaries. In the first bay of the north side of the Angel Choir is a remarkable monument, part of which once served for an Easter sepulchre. This, like those of Navenby and Heckington of the same date, is richly carved with oak and vine and fig-tree foliage, and shows the Roman soldiers sleeping. Opposite, on the south side, are the tombs of Katharine Swynford of Ketilthorpe, Duchess of Lancaster, Chaucer’s sister-in-law, whose marriage to John of Gaunt took place in the minster in 1396. Like so many of the monuments, these are sadly mutilated, and are not now quite in their original position. It is on one of the pillars of the east bay, the second from the east end, that the curious grotesque, familiar to all as the “Lincoln Imp,” is perched. [Sidenote: THE NAVE]
