Rhodo (1), a Christian writer of the
end of the 2nd cent., our knowledge, of whom now
exclusively depends on the account of his
writings, and some extracts from them in
Eusebius (H. E. v. 13). He was a native of
Asia, converted to Christianity at Rome by
Tatian, as he himself says in a treatise against
Marcion addressed to Callistion. In it he
tells of the sects into which the Marcionites
split up after Marcion's death, and gives an
interesting account of an oral controversy held
by him with the Marcionite , then an old man. He mentions a book of "Problems" published by Tatian, intended to exhibit the obscurity of the Holy Scriptures, and promise to give the solutions; but Eusebius does not seem to have met with this work. He also wrote a treatise on the Hexaemeron. Through a lapse of memory Jerome (de Vir. Ill.) speaks of him as author of the anonymous treatise against the Montanists from which Eusebius makes extracts (H. E. v. 16).
