Ignatius is a difficult name to explain.  Its associations are with the Eastern Church, but it occurs at a time when Latin names prevailed as much as Greek ones in the Asiatic portions of the Roman empire, and thus the Latin ignis (fire) is, perhaps, the most satisfactory derivation, though it is not unlikely that the word may come from the source both of this and of the Greek ἁγνός, purity and flame being always linked together in Indo-European ideas.
    The birth-place of the great St. Ignatius is unknown, but tradition has marked him as the child whom our Lord set in the midst of His disciples, and he is known to have been the pupil of St. John, ordained by St. Peter, and at the end of his long episcopate at Antioch, he was martyred at Rome by command of Trajan, writing on his last journey the Epistles that are among the earliest treasures of the Church.  So much is his memory revered in his own city, that to the present day the schismatic patriarchs of Antioch of the Monophysite sect uniformly assume the name of Ignatius on their election to their see.
