[What was Montpellier's theriac].

The long-lasting fame of Montpellier's theriac does not come from the originality of its composition. In the Middle Ages, its formula followed Antidotarium Nicolai's while, in the modern period, it copied Galen's. This fame is explained by the reputation of the medical University, by the dynamism of its apothecaries and by the strength of Montpellier's trade networks.
