In Living Latin: A Graded Reader (The Paideia Institute), Chapter XXXIX contains the following sentence:
Et deinde Caesar ultima voce fertur Marco Bruto dixisse 'Et tu Brute'
I parse it as:
(Et deinde) fertur (Caesar (ultima voce) (Marco Bruto) dixisse 'Et tu Brute')
But why does the clause introduced by "fertur" not have its subject in the accusative?
