Library Eusebius of Caesarea Life of Constantine
Book 1, Chapter 35: Massacre of the Roman People by Maxentius.
All men, therefore, both people and magistrates, whether of high or low degree, trembled through fear of him whose daring wickedness was such as I have described, and were oppressed by his grievous tyranny. Nay, though they submitted quietly, and endured this bitter servitude, still there was no escape from the tyrant's sanguinary cruelty. For at one time, on some trifling pretense, he exposed the populace to be slaughtered by his own bodyguard; and countless multitudes of the Roman people were slain in the very midst of the city by the lances and weapons, not of Scythians or barbarians, but of their own fellow citizens. And besides this, it is impossible to calculate the number of senators whose blood was shed with a view to the seizure of their respective estates, for at different times and on various fictitious charges, multitudes of them suffered death.
