In 1985, a research paper by Fitton Brown advanced new arguments in support of Hartman's theory. Brown's article was followed by a series of supports and refutations in the short space of five years. Among the supporting reasons Brown presents are: Ovid's exile is only mentioned by his own work, except in "dubious" passages by Pliny the Elder and Statius, but no other author until the 4th century; that the author of "Heroides" was able to separate the poetic "I" of his own and real life; and that information on the geography of Tomis was already known by Virgil, by Herodotus and by Ovid himself in his "Metamorphoses".
