Short answers, pulled from the story.
Nicholas Bourbon the elder (1503 - after 1550) was a French court poet and preceptor who wrote a collection of Latin poems titled Nugae (Trifles), known in French as Bagatelles. He is notable for his connections to Anne Boleyn, Hans Holbein the Younger, François Rabelais, and the humanist circle in Lyon, and for having been imprisoned in France for writings sympathetic to religious reform before being freed by Francis I in 1535.
Bourbon was imprisoned after publishing the first edition of Nugae in 1533, which contained an epigram, In laudem Dei optimi maximi, that appeared favorable to religious reform. The work also reportedly included subtle criticisms of Noël Béda, a theologian and opponent of humanist thinkers. Despite appeals to multiple patrons and a royal commandment calling for his release, he remained imprisoned until Francis I freed him in 1535.
Bourbon traveled to England in 1535 to pay homage to Henry VIII and Anne Boleyn in gratitude for their help during his persecution in France. Anne Boleyn, a proponent of moderate evangelical reform, helped Bourbon find work as a tutor at the English court. Bourbon later wrote a series of poems describing Anne Boleyn as one of God's beloved servants.
Hans Holbein the Younger was among Bourbon's circle during Bourbon's time at the English court in 1535, when Holbein was making his second stay there. Holbein drew Bourbon's portrait in 1535. Bourbon expressed deep admiration for Holbein, calling him "the Apelles of our time."
The école lyonnaise, or Lyonnaise School, was a group of poets and humanists in Lyon who gathered around Étienne Dolet after Bourbon returned to France in 1536. Members included Jean Visagier, Eustorg de Beaulieu, Gilbert Ducher, and Symphorien Champier. Bourbon was a regular member of the group and within it encountered François Rabelais.
Around 1540 Bourbon became preceptor to Jeanne d'Albret, the daughter of Marguerite de Navarre. Earlier in his career he had also served as tutor to the household of the Cardinal of Tournon and taught humanities in Amiens, Langres, and Troyes.
