[Footnote 45: Muratori (dissert. xlii. tom. iii. p. 785 -
788) has published an original treaty: Concordia inter D.
nostrum papam Clementem III. et senatores populi Romani
super regalibus et aliis dignitatibus urbis, &c., anno 44
Degrees senatus. The senate speaks, and speaks with
authority: Reddimus ad praesens .... habebimus .... dabitis
presbyteria .... jurabimus pacem et fidelitatem, &c. A
chartula de Tenementis Tusculani, dated in the 47th year of
the same aera, and confirmed decreto amplissimi ordinis
senatus, acclamatione P. R. publice Capitolio consistentis.
It is there we find the difference of senatores consiliarii
and simple senators, (Muratori, dissert. xlii. tom. iii. p.
787 - 789.)]
