τῶν ἀνακτόρων Ανάκτορον in classical Greek = temple or shrine, e.g. Eur. And. 43 “Θέτιδος ἀνάκτορον.” Archd. Cheetham (Dict. Christ. Ant. i. 79), quoting Lobeck, says “also the innermost recess of a temple.” Eusebius (Orat. ix) uses it of the great church built by Constantine at Antioch. Theodosius was already within the Church. The sacrarium was in Greek commonly τὸ ἅγιον, or τὸ ἱερατεῖον. The 31st canon of the first Council of Braga ordains “ingredi sacrarium ad communicandum non liceat laicis nisi tantum clericis.”
