His apparently promising diplomatic career was, however, cut short by an attack of deafness that no physician could cure, and he determined to devote himself to study. The institution he chose for the purpose among the numerous schools and colleges of Paris was the Collège Coqueret, the principal of which was Jean Daurat — afterwards the "dark star" (as he has been called from his silence in French) of the Pléiade, and already an acquaintance of Ronsard's from having held the office of tutor in the Baïf household. Antoine de Baïf, Daurat's pupil, accompanied Ronsard; Belleau shortly followed; Joachim du Bellay, the second of the seven, joined not much later. Muretus (Marc Antoine de Muret), a great scholar and by means of his Latin plays a great influence in the creation of French tragedy, was also a student here.
