At the same time that Calvin was anxious to conciliate persons of importance he took great pains to secure publicity and success for his book. On the 22d April, 1532, he wrote to his friend Francis Daniel, at Orleans, 'The die is cast: my commentaries on Seneca's treatise "De CLementia" have appeared; but they are printed at my own expense and have cost me more money than you will believe. I am now trying to gather a little of it in again. If you wish to help me in that way I will send you a hundred copies, or as many as you think it well to take. Meanwhile accept the copy which I send you, and do not think that I impose any law upon you in this matter, for I wish you to feel perfectly free in all your dealings with me.' {164} Calvin was not slow in recognising that in the presence of questions and passions which agitated men's minds more violently from day to day, prudence and conciliation were of very little use, and that, whether for defence or attack, it was necessary to have recourse to more powerful weapons. He was one of those who do not rush to the fore-front of every struggle, but who, at the same time, will not make any sacrifice of their own belief or opinion to avoid a contest, and who enter into it heart and soul when once it becomes inevitable. Before long an incident occurred which gave rise to this necessity. Calvin was very intimate with Nicholas Cop, rector of the University of Paris, who in virtue of his position was to deliver a discourse on All Saints' day, in 1533, at the church of the Mathurins. Calvin offered to compose the sermon, and 'constructed a very different kind of oration,' says Beza, 'from the ordinary one, for he spoke of religious matters with great freedom, and in a liberal tone of which the Sorbonne and the "Parlement" did not at all approve; so much so that the "Parlement" sent to seek Nicholas Cop, and he set out to go to them with his attendants; being warned, however, that they intended to imprison him, he did not go to the palace, but turned back and fled from the kingdom, going to Basle, the native place of his father, William Cop, physician to the king, and a man of great renown.' [Footnote 55] Calvin also was accused, and Jean Morin, the judge in criminal causes, went to his rooms and examined all his papers, with the intention of arresting him. Calvin had been warned, however; he 'escaped by the window, took refuge in the Faubourg St. Victor, at the dwelling of a vine-dresser, changed his clothes,' and left Paris, scarcely knowing whither he was going.
