Theorist. From 1305 to 1307
maestro di canto
at the Cathedral of Padua; from 1308 resident in various other
Italian cities, including Cesena and Verona. His principal
theoretical works are
Lucidarium
and
Pomerium.
These treatises provide the most complete known 14th-century
explanation of Italian
trecento
theory. The
Lucidarium,
which covers the basics of traditional music theory and of
plainchant, includes an original and highly influential section
setting forth a division of the whole tone into five parts. The
Pomerium
deals with mensural music, emphasizing notation in the Italian
manner. Both were widely known and were claimed as authorities,
quoted, or argued against, by many later writers.
