Nicolas Lami, Amici, was cursor in theology in 1422, bachelor in 1423, licentiate at Paris in 1428, rector in 1426 and 1429.

By virtue of letters royal from Henry, he took possession of the canonicate of Jean Chuffard at Beauvais in Cauchon's time. He was present only one day at the Trial and departed immediately for the Council of Bâle where he arrived about the ninth or twelfth of April, 1431.

Nicolas Lami played an important part in the Council. On October 18, 1431, he wrote to Chancellor Rolin, to have him intervene in the matter of the Burgundian captains who were operating between Belfort and Altkirsch, threatening the security of the environs of Bâle.

On March 18, 1432, at Paris, he delivered before Parlement a chronicle of events of the Council and protested with utmost violence against its dissolution "to the great shame and infamy of the Pope."

We find Nicolas Lami in charge of missions for the Council at Cologne, in France and in England. On March 10, 1436, the Council decided to confer upon him a canonicate at Tournai. On November 10, 1439, he was summoned to Bourges by Charles VII at the time of his consultation with the clergy of France. We find him again, in 1447, at the conference at Lyons, which was to settle the question of the abdication of Felix V.

We know that at Bâle Nicolas Lami met the celebrated Alsatian doctor, Jean Nider, prior of the Dominicans and author of the Formicmium, which he had written to direct the religious of his order in research in heresy.

This "very zealous discoverer of witches" to use Trithème's phrase, received from Lami his information on Jeanne d'Arc and on the two women who said they came from God who were condemned at Paris.

In the words of Nicolas Lami, Jeanne "had avowed familiarity with an angel of God, who, in the opinion of a great number of very lettered persons, was only an evil spirit, and likewise this was the result of many proofs and conjecture."
