DINIAE a place in Phrygia, through which the Roman consul Cn. Manlius marched in his Galatian expedition. (Liv. 38.15.) He came to the plain of Metropolis [METROPOLITANUS CAMPUS], and on the following day to Diniae. From Diniae he marched to Synnada; but there is no indication of the length of the march from Diniae to Synnada. Hamilton observes that Strabo (p. 663), in a passage where he describes the great line of communication between Ephesus and Mazaca, places Metropolis (clearly the same as that alluded to by Livy) between Apamea and Chelidonii, probably the same place as the Diniae of the historian.( Researches, &c. vol. 2. p. 179.) Hamilton concludes that the plain of Sitzhanlirepresents the Metropolitanus Campus; both from the narrative of Livy and its being on the great line of traffic.This seems a very probable conclusion. He also thinks that Afiom Kara Hissaris the representative of Synnada; and if he is right in these conclusions, the position of Diniae is fixed within certain limits, though the maps do not show any name that corresponds to it.
It is generally agreed that the words καὶ Χελιδονίωνin Strabo (p. 663) are corrupt; but it is doubtful if Livy's Diniae is concealed under it. Cramer (Asia Minor, vol. 2. p. 30) and Groskurd ( Transl. Strabo, vol. 3. p. 63) have some remarks on this reading. Palmerius proposed καὶ Φιλομηλίου, against which Cramer's objection is insufficient.
