4. (West side) In te Domine speravi: non confundar (In Thee, O Lord, have I trusted: let me never be confounded).
The roof has a continuous system of decoration in colour and floral ornament, except in the four compartments at the extreme east end over the apse, where structural necessities imposed a variation. The central space of the roof is filled with scrolls containing the words, Laus, Potestas, Honor, Gloria, in ecclesiastical letter, varied by insertions of the monogram of the Saviour, I.H.S., at intervals recurring. "Below these, and towards the junction of the roof with walls, appears what may be called a flying scroll of inscriptions, being a series of Latin texts and chants, chiefly from the Vulgate, capable of being read continuously, round the roof, and interrupted only by the apse, which, as explained, has a separate treatment." "In the apse, which, like Scottish apses of that period, is not semicircular, but has three facets, being semi-hexagonal, the frieze inscriptions are the University motto in its two clauses, with Sursum Corda in the centre. These occupy severally the three divisions into which the apse frieze falls, while in the compartments above are the symbolical figures in gold usually associated with the four Evangelists, viz. the Angel of S. Matthew, the Lion of S. Mark, the Ox of S. Luke, and the Eagle of S. John. The flying scroll attached to these figures is the text in Revelation (iv. 8). The band at the springing of the arched roof is variegated by a series of shields or disks, in which the sacred monogram alternates with the emblems of the Passion. The order in which the emblems have been placed is as follows:
West End
| South side ends. | North side begins. |
| 15. Moon. | 1. Sun. |
| 14. Ladder. | 2. Bag of Judas. |
| 13. Spear and Sponge. | 3. Lantern. |
| 12. Dice. | 4. Cock. |
| 11. Seamless Coat. | 5. Scourges. |
| 10. Hammer and Pincers. | 6. Pillar and Cords. |
| 9. Three Nails. | 7. Crown of Thorns. |
| 8. Cross, I.N.R.I. |
East or Apse End
"The figures of the sun or moon, which are usually represented in the Crucifixion scene, on either side of, and close to, the cross, have here by a certain liberty been made to commence and close the series." ... "Fortunately the fretwork, when reversed, was found, though fragile, to be fairly sound; and, although not all entirely on a uniform pattern, a large section of it, when turned upward, presented the appearance of a series of Pots of Lilies, side by side, a discovery which largely reconciled one to the alteration, inasmuch as this emblem of the Virgin is known to have been not only familiar to, but also a favourite with, the Founder of the College. The King's College, besides, was originally the College of S. Mary."
Chancel and Apse
The Professorial stalls have for the cresting the emblems of the Seven Virtues, viz. the four cardinal virtues of the Philosophers, and the three celestial virtues, or Graces of the Theologians. The sequence is:—
| {1. Justice, | symbolised | by the | Scales and Balance. |
| {2. Courage | " | " | Thistle. |
| {3. Temperance | " | " | Bridle. |
| {4. Prudence | " | " | Compasses (Mariner's and Carpenter's). |
| {5. Faith | " | " | Pillar with Wreath of Victory. |
| {6. Hope | " | " | Anchor. |
| {7. Love | " | " | Flaming Heart. |
They are repeated in such order on both sides, and the four Cardinal Virtues are towards the west or exterior; the three Theological Virtues toward the east or interior of the apse. On the stall forming the eighth on the south side, there is the monogram of the Alpha and Omega. On the panels of the stalls, "the leading idea sought to be maintained was the representation in sequence of the various emblems of Christ and the Christian life, as drawn from the cornu copiæ of Nature, in the fruits and flowers of the vegetable world, that unfallen portion of creation which the Divine Teacher honoured by drawing from it, and from it alone, His similes and parables. They are severally as follows, commencing from the west:—
