After Paulinus' death in 388, the Eustathians still resented Flavian for his relation to the hated Meletius, accused of being consecrated by Arians. So they elected Evagrius. According to Sozomen, he didn't last long.
According to Theodoret, the consecration of Evagrius by Paulinus was against canon law, because he did it alone, in his death bed. Nonetheless, he was accepted by the emperor and thus the schism persisted.
