The Telesterion took up the greater part of the sacred precinct, which seems merely to have served to keep the profane away from the temple. The massive walls and towers of the time of Pericles, which resemble those of a fortress, are quite close in on the south and east; later, probably in the 4th century B.C., the precinct was extended farther to the south, and at its end was erected a building of considerable extent, including a curious apsidal chamber, for which a similar but larger curved structure was substituted in Roman times. This was probably the Bouleuterion. The precinct was full of altars, dedications and inscriptions; and many fragments of sculptures, pottery and other antiquities, from the earliest to the latest days of Greece, have been discovered. It is to be noted that the subterranean passages which some earlier explorers imagined to be connected with the celebration of the mysteries, have proved to be nothing but cisterns or watercourses. The excavations of Eleusis, and the antiquities found in them, have been published from time to time in the [Greek: Ephêmeris Archaiologikê] and in the [Greek: Praktika] of the Greek Archaeological Society, especially for 1887 and 1895. See also D. Philios, _Éleusis, ses mystères, ses ruines, et son musée_. Inscriptions have also been published in the _Bulletin de correspondance hellénique_. (E. Gr.) ELEUTHERIUS, pope from about 175 to 189. Allusions to him are found in the letters of the martyrs of Lyons, cited by Eusebius, and in other documents of the time. The _Liber Pontificalis_, at the beginning of the 6th century, says that he had relations with a British king, Lucius, who was desirous of being converted to Christianity. This tradition--Roman, not British--is an enigma to critics, and, apparently, has no historical foundation. (L. D.*)
