Eusebius was a 
Pope in the year 
309.  His 
pontificate lasted only from April 18 to August 17, after
which, in consequence of disturbances within the
Church which led to acts of violence, he was 
banished by the tyrant 
Maxentius, who had been the
sole ruler of 
Rome since April 308, and had at first
shown himself friendly to the 
Christians. The 
difficulty arose, as in the case of his predecessor 
Pope Marcellus I, out of his attitude toward the 
Lapsed[?],
which represented the milder standpoint. 
Eusebius died
in exile in Sicily, and was buried in the cemetery
of Calixtus, his successor Damasus placing an
epitaph of eight hexameters over his tomb; the
epithet "martyr" contained in them is not to be
taken in the strict sense. 
His feast is on September 26.
- preceded by Pope Marcellus I, (308-309)
- succeeded by Pope Miltiadesl, (311-314)
