Garlandia, Johannes de

Lived about the Thirteenth Century

Writer on musical subjects, was the author of a treatise on plain chant, and several works on mensural music, which have been by some authorities ascribed to Gerlandus, a mathematician of the Twelfth Century; but later their author was conceded to be identical with the grammarian, Garlandia, who seems to have been active in the earlier half of the Thirteenth Century in England and France, and who wrote poems on religious and historical themes. Riemann names a second writer, sometimes called Galandia, of the latter half of the Thirteenth Century, still living in the Fourteenth, as the author of the treatise on plain chant above mentioned.
