Jean-Antoine de Baïf (1532 – 1589) was a French poet, son of Lazare de Baïf, a humanist and ambassador. He was one of the seven members of 'La Pléiade', a literary group that aimed to enrich the French language and create a national poetry of great quality, drawing inspiration from classical models. Baïf experimented with new poetic forms, including the creation of a metric system based on syllable duration (similar to ancient Greek and Latin), although with limited success. He also founded the 'Académie de Poésie et de Musique' in 1570, with the aim of restoring harmony between poetry and music. His work, although less celebrated today than that of some of his Pléiade contemporaries, represents an important step in the evolution of French poetry.
