So earnest were they to utilize--we may say secularize--the old structure, that even the spaces on the outside, between the butresses, were from A. D. 1555 down to 1817, a period of 262 years, filled in with small shops, whose chimneys belched smoke against the old edifice. This was the parish church of Edinburgh at the Reformation, and is celebrated as the place where John Knox made his appeals to the piety and patriotism of the metropolis,--appeals which, more than all other means, established the Reformation not only in this country, but the civilized world over. An exciting scene took place here in 1637. Archbishop Laud had arranged for the introduction of the liturgy, to establish by authority the service of the Church of England. As the custom was, Jenny Geddes brought a stool with her to church, and when the obnoxious prayers were begun, and the Bishop of Edinburgh had just requested the Dean to read the Collect for the day, Jenny arose and exclaimed: "_Colic_, said ye; the Devil colic the wame o' ye; wud ye say Mass at my lug?" and she sent her stool flying at the Dean's head. The famous stool is still preserved in the Antiquarian Museum. The ancient cemetery of the church is now covered by the second House of Parliament, and used as a court-house. John Knox died Nov. 24, 1572. He was buried in the burial-ground not far from the church. This large area is now the approach to the court-house, and is paved with large flagstones. As nearly as can be ascertained, this burial-place is designated by the letters J. K., cut in one of these stones; and this is the only monument that Edinburgh can show for one of her greatest citizens. Over the grave of Knox was once a stone with that celebrated epitaph by Regent Morton:-- HERE LIES HE WHO NEVER FEARED THE FACE OF MAN. On the outer walls of St. Giles's is a monument to John Napier, who died here April 4, 1617, and was celebrated as the inventor of logarithms. The Tolbooth was originally a parliament house, and at last a prison. It is referred to in Sir Walter Scott's "Heart of Midlothian," and is marked as the northwest corner of St. Giles's by the figure of a heart cut in the pavement. The house in which Knox resided is one of the quaintest imaginable. It is not far from St. Giles's, and is very irregular in outline, of a dark brown color, three and a half projecting stories in height. He occupied it from 1560 to 1572, when he died in the 67th year of his age. Over the door is the inscription:-- LUFE GOD ABUF ALL, AND YE NYCHTBOUR AS YISELF.
