370 Journal of Philology. It is only fitting that next to the Heraeon of Samos Yitruvius should place the Artemision of Chersiphron and Metagcncs, for Theodorus it was who, according to a noted story, prepared the ground on which those architects erected the temple in question. With regard to Phylcos, the architect of the very beautiful temple of Pallas Pollias at Priene (erected about 01. 110), it seems~very generally agreed, from a comparison of various pas- sages in Vitruvius, that one and the same artist figures in that author under four different names, Phylcos, Phyteus, Pythius and Pytheus. This view, in which I agree, identifies the builder of the temple at Priene with that of the Mausoleum mentioned lower down. Tetinus and his works are too famous to need any comment. I therefore pass on to Philo, the builder of the basin in the Piraeus. Sillig and Vossius both conjecture that this Philo may be the same as the nqxavoypacpos, or Philo Byzantius mentioned lower down by Vitruvius among the authors 'de machinationibus.' If the statements under this name in the Dictionary of Biography anal Mythology, pp. 306, 314, may be relied on, this conjecture would fall to the ground. I am so loath to doubt the accuracy of the writer, which rarely fails him, that I am driven so plausi- ble is the conjecture to suspect the trustworthiness of the authorities from whom he has gathered his information with reference to the date of the architect. As to Philo Byzantius, I may mention here, that in the recent edition of his works by Kochly and Riistow (Leipzig, 1853) one of the most intricate portions of Vitruvius (x. 10 seqq.) meets with hitherto unhoped- for elucidation. The remaining architects and authors enumerated by Vitru- vius are too obscure to make it worth our while to pursue the enquiry any further. More than sufficient indications are afforded us, that Vitruvius had invaluable written sources at his command, if he only knew how to use them. To say that he was incapable of doing this, might appear flippant and presumptuous. This much, however, must at least be allowed, that he cannot have availed himself of his resources to the extent that fairly might have been expected from him. An expression of which he some- whore makes use, " nos autem exponimus quemadmodum a prajceptoribus accepimus," gives us a very good idea of the way in which he executed his work ; I mean, that he copied his
