Аннотация:Mathematical education was part of the encyclopedic program of Baïf's Academy and its ofishoot the Palace Academy, as Miss Frances Yates has aptly shown. But who were the teachers? She has speculated that the classical archeologist Louis de Montjusieu taught mathematics to the Duc de Joyeuse at the Academies rather than privately. An analysis of the interests and contacts of a number of mathematicians in the Paris area during the 1570's and 1580's adds to her speculation several masters of mathematics, three of whom will be discussed here.
