A question, and a possible correction.<BR>
<BR>
Has the dating on "Odo" been revised? I had always thought he predated<BR>
Guido of Arezzo by a few years. (The online NGD2 entry on modal theory<BR>
still lists him as such, as of 10 min. ago...:)<BR>
<BR>
Guido definitely uses the seven-letter notation system in both the _Regule<BR>
rithmice_ and the _Micrologus_, using an analogy to the 7 days of the week<BR>
that I believe is also used by Ps-Odo--no access just at the moment to check.<BR>
No idea if that analogy is original with Ps-Odo or was some sort of common<BR>
coinage--if anyone has info one way or another on that I'd love to hear it.:)<BR>
