For a little while there was calm at Louvain, calm before the storm, and the patricians had almost begun to hope that their trouble with Coutherele was over, when presently it was rumoured abroad that his nephews were tampering with the weavers. Employers of labour, comparing notes, called to mind that of late their men had shown themselves idle beyond wont, sullen, fractious, insolent; they had wondered what this meant, now they knew the reason. When the days grew longer, and honest merchants came forth after supper to cool themselves with the evening breeze, they noted that the loungers, muttering together in market-place and at street corner, leered at them as they passed with evil eyes, and scarce vouchsafed to lift their hats.

Mischief, it was clear, was brewing. At last the plot was discovered, and then the crisis came. Edmund De Dynter tells us how it all happened.

On the evening, he says, of the Feast of St. Mary Magdalen (July 21), in the year of Our Lord 1360, it came to pass that a certain meschine in the service of one of our magistrates, having been sent by him to a certain tavern to fetch a flask of wine, fell in with her sweetheart, who in confidence told her that the people, egged on by Peter Coutherele, intended to rise that night against the patricians, take possession of the Town Hall, and make a pretty piece of mischief (faire aulcune mauvaise oevre). Of course she divulged the secret to her master, and he without delay imparted the same to his brother aldermen, who forthwith betook themselves to the Town Hall, and arrived there amazed and confounded at the manifest evidence of commotion which they had witnessed on the way, for by this time the night was restless with the tumult of a gathering mob: men were hurrying from all sides to the great market behind the Cloth Hall, where the Mayor of Louvain was already addressing a crowd of weavers, 'with arms in their hands and anger in their brains.'

And what had Myn Here Coutherele to say for himself? If we may trust De Dynter, who wrote indeed more than fifty years afterwards, he began by enlarging on the misery of the people, and on the pride, the wealth, the corruption, of those who held them in bondage, and who fattened on their toil and on their tears. Was it not the people who paid the taxes, and the patricians who had the spending of them? Did not the poor man have to bear the heat and the burthen of the day whilst the rich were growing richer on the spoils of administration? And what right had these men to lord it over them? Were they not their fellow-citizens, of like birth and of like origin with themselves? And when he saw that he had enkindled their ire, he said that now was the time to strike; their oppressors were at their mercy, they had mortally offended the Duke, he would close his eyes and close his ears to aught which might be attempted against them. It were madness to lose so favourable an opportunity, let them then take up arms for dear liberty's sake.

It chanced that a certain great feudal lord, one Gerard of Vorsselaer, was in town that day along with a band of retainers. This man seems to have been esteemed in Louvain, and having no personal interest in city affairs, he was on friendly terms with the leaders of each party. Having vainly endeavoured to dissuade Coutherele from his purpose, he made his way, as best he could, to the Town Hall and offered his services to the patricians. 'Let them come forth like men and face the mob, and he and his followers would help them de bon coer et de bon courage. For,' said he, 'the people have not yet had time to muster; if we go forth now, I doubt not that with God's help we shall put to shame the handful that are already in the market-place, and when the rest behold their discomfiture they will run to cover like poulets that have spied a hawk.'

Sound advice probably, 'but those hommes de loy were men of such frail and meagre courage' that they deemed it too hazardous. Whereat Vorsselaer, disgusted, incontinently leapt into his saddle and made for Brussels, where we shall presently meet him. Meanwhile the mob was increasing each moment in fury and in numbers, and the patricians, thus left to their own devices, very soon came to the conclusion that no other course was open to them but to treat with Myn Here Coutherele. They did so, and with this result. To their envoy he made reply that the people would fain be assured that the city accounts were in order. Let the doors of the Town Hall be opened, and he and his friends would enter and examine their books, and, when they had done so, withdraw. The patricians complied, and Coutherele kept faith to the letter, nay, he went even beyond his bond, for not only did he examine the account books, he made a bonfire of them, and added thereto the charters of patrician privileges and all other parchments he could set hands on; and when at last he and his friends withdrew, they took care to bring their opponents with them disarmed and under arrest.

Thus did the old régime at Louvain come to an inglorious end. The patricians had not struck a blow in defence of their privileges, and the fact that the revolution was accomplished without bloodshed bears witness not only to the humanity and moderation of Coutherele, but to the marvellous influence which he must have had over the mob. Next morning Coutherele himself, who was now practically dictator, named a new magistracy, consisting of four patricians, men who were known to favour the people, and three plebeians. It was the first time that a commoner had been named alderman in any town of Brabant.

Meanwhile the men who had been captured in the Town Hall were still in prison, and presently their friends made private appeal to Duchess Jeanne, who opened communications with Coutherele with a view to their liberation. Perhaps it was the policy of neither party to come to an understanding; in any case, after several weeks had elapsed and nothing had been effected the negotiations were broken off. Whereat the prisoners, fearing for their lives, which after all hung by a thread, proceeded themselves to treat with the all-powerful dictator, and with better results, for after some haggling they purchased their freedom upon undertaking to quit the city as soon as they should be set at liberty.

The ransom which each man paid was assessed in proportion to his means, but the sum-total thus realised amounted to a very large figure, and his enemies said that, by this transaction, Coutherele had made himself one of the richest men in Brabant, but in reality he expended the whole of this fund, or, at all events, the greater portion of it, in the purchase of the new charter which Duke Winceslaus granted to the city of Louvain in the month of September 1360.

In this remarkable document, which was no doubt drawn up by Coutherele himself, the Duke gave legal sanction to the changes accomplished in July. He fully recognised the claim of the plebeians to participate in the government of the city; he decreed that henceforth three aldermen and eleven jurors should be chosen from among their ranks, and that all other municipal functions should be equally divided between the two classes. The elections were to take place annually, the plebeian members being named by the patricians and the patrician members by the plebeians—a very prudent regulation, calculated to secure in each case the return of moderate men.
