EUTYCHIANUS, yk-tik'+-"nus : Pope 275-283. His name occurs in the lists of bishops of Rome between Felix and Caius, and a pontificate of eight years, nine months, and three days is assigned to him. Nothing at all is known of the events which marked it; but it may be mentioned that the tablet which covered his grave in the so-called "vault of the popes" has been discovered (cf. F. X. Kraus, Roma sotterranea, Freiburg, 1879, 154).
