Dr. Wren, afterwards Sir Christopher, was now called upon to produce his designs; he had before drawn several, in order to discover what would be most acceptable to the general taste; and finding that persons of all degrees declared for magnificence and grandeur, he formed a very noble one, conformable to the best style of the Greek and Roman architecture, and having caused a large model to be made of it in wood, with all its ornaments, he presented it to his Majesty; but the Bishops not approving of it, as not enough of a cathedral fashion, the Surveyor was ordered to amend it, upon which he produced the scheme of the present structure, which was honoured with his Majesty’s approbation. The first design, however, which was only of the Corinthian order, like St. Peter’s at Rome, the Surveyor set a higher value upon than on any other he ever drew, and as the author of his life observes, would have put it in execution with more cheerfulness, than that which we now see erected. This curious model is still preserved in the cathedral, and may be seen at a small expence.
In the year 1675, Dr. Wren began to prosecute the work; the pulling down the old walls, which were eighty feet high, and clearing the rubbish, had cost many of the labourers their lives; and this put him upon contriving to facilitate its execution by art. The first project he tried was with gunpowder; for on their coming to the tower of the steeple, the men absolutely refused to work upon it; for its height struck the most hardy of them with terror. He therefore caused a hole of about four feet wide to be dug in the foundation of the north west pillar, it being supported by four pillars each fourteen feet diameter, and then with tools made on purpose, wrought a hole two feet square into the center of the pillar, in which he placed a little deal box, containing only eighteen pounds of powder. A cane was fixed to the box with a match, and the hole closed up again with as much strength as possible.
Nothing now remained but to set fire to the train, and the Surveyor was exceeding curious to observe the effect of the explosion, which indeed was wonderful; for this small quantity of powder not only lifted up the whole angle of the tower, with two arches that rested upon it; but also the two adjoining arches of the isles, and all above them; and this it seemed to do somewhat leisurely, cracking the walls to the top, and lifting up visibly the whole weight about nine inches, which suddenly tumbling to its center, again caused an enormous heap of ruin, without scattering, and it was half a minute before this huge mountain opened in two or three places and emitted smoke. The shock of so great a weight from a height of two hundred feet, alarmed the inhabitants round about with the terrible apprehensions of an earthquake.
A second trial of the same kind, was made by a person appointed by Dr. Wren, who being too wise in his own conceit, disobeyed the orders he had received, put in a greater quantity of powder, and omitted to take the same care in closing up the hole, or digging to the foundation; but though this second trial had the desired effect, yet one stone was shot as from the mouth of a cannon to the opposite side of the church yard, and entered a private room where some women were at work; but no other damage was done, besides spreading a panic among the neighbours, who instantly made application above against the farther use of gunpowder, and orders were issued from the council board accordingly.
The Surveyor being now reduced to the necessity of making new experiments, resolved to try the battering ram of the ancients, and therefore caused a strong mast forty feet long to be shod with iron at the biggest end, and fortified every way with bars and ferrels, and having caused it to be suspended set it to work. Thirty men were employed in vibrating this machine, who beat in one place against the wall a whole day without any visible effect. He however bid them not despair, but try what another day would produce; and on the second day the wall was perceived to tremble at the top, and in a few hours it fell to the ground.
In clearing the foundation, he found that the north side had been anciently a great burying place; for under the graves of these latter ages, he found in a row the graves of the Saxons, who cased their dead in chalk stones; tho’ persons of great eminence were buried in stone coffins: below these were the graves of the ancient Britons, as was manifest from the great number of ivory and wooden pins found among the mouldered dust; for it was their method only to pin the corpse in woollen shrouds, and lay them in the ground, and this covering being consumed, the ivory and wooden pins remained entire.
At a still greater depth he discovered a great number of Roman potsheards, urns, and dishes, sound, and of a beautiful red like our sealing wax; on the bottoms of some of them were inscriptions, which denoted their having been drinking vessels; and on others, which resembled our modern sallad dishes, beautifully made and curiously wrought, was the inscription DZ. PRIMANI. and on others, those of PATRICI. QUINTIMANI. VICTOR. IANUS. RECINIO, &c. The pots and several glass vessels were of a murrey colour; and others resembling urns, were beautifully embellished on the outsides with raised work, representing grey hounds, stags, hares, and rose trees. Others were of a cinnamon colour, in the form of an urn, and tho’ a little faded, appeared as if they had been gilt. Some resembling juggs formed an hexagon, and were curiously indented and adorned with a variety of figures in basso relievo.
The red vessels appeared to have been the most honourable; for on them were inscribed the names of their deities, heroes, and judges; and the matter of which these vessels were made, was of such an excellent composition, as to vie with polished metal in beauty.
There were also discovered several brass coins, which by their long continuance in the earth were become a prey to time; but some of them that were in a more favourable soil, were so well preserved as to discover in whose reign they were coined: on one of them was Adrian’s head, with a galley under oars on the reverse; and on others, the heads of Romulus and Remus, Claudius and Constantine.
At a somewhat smaller depth were discovered a number of lapilli or tesselæ, of various sorts of marble, viz. Egyptian, Porphyry, Jasper, &c. in the form of dice, which were used by the Romans in paving the prætorium, or General’s tent. Conyers M. S. in the Sloanian library, in the Museum.
