Admetus de Aureliana
- Andrew Wathey
(flc1300–30; d ? c1330). French theorist. He may be identifiable with Amis d'Orléans, a notary in the French royal chancery, 1301–29, who was a contemporary of Gervès du Bus (see Fauvel, Roman de); Amis was appointed king's secretary in 1316, became Archdeacon of Orléans in 1309 and Dean of Notre Dame, Paris, in 1323. Admetus's work is cited in rubric IX (rules 12–14) of Robert de Handlo's Regule, which was completed in Paris in May 1326. These passages describe the mensuration of semibreves, and ascribe to singers of Navarre (cantores de Navernia) the practice of using stems (respectively vertical ascending and oblique descending) to differentiate minimae and minoratae. This may perhaps corroborate the remark made by John of Tewkesbury in his Quatuor principalia that the minima was invented in Navarre (‘minima autem in Navarina inventa erat’).
