A Strange Star

Τὸ ἐν τῇ θείᾳ πτυκτῇ περὶ τοῦ ἀστέρος φερόμενον, Ἐλθὼν ἔστη ἐπάνω οὗ ἦν τὸ παιδίον, ἐμφανέστερον ὑποδείξει σοι, οὐ τὴν συνήθη τῶν ἄστρων πορείαν ποιησάμενον τὸν εὐαγγελιστὴν τοῦ θείου τόκου ἀστέρα, οὐδε γὰρ ἡ τοῦ ὕψους διάστασις, εὐχερῆ, ἐποίει τοῦ ζητουμένου τὴν εὕρεσινὶ, ἀλλ' ἑτέραν τινὰ καινοτέραν ἐκείνης, ὡς δακτύλῳ τῷ ἐξηλλαγμένῳ δρόμῳ μηνύουσαν, τό τε ἅγιον ἄντρον, καὶ τὴν ἐν αὐτῷ Κυριοφόρον καὶ σεβάσμιον φάτνην. Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλιον Πρῶτον, Ἐπιστολή ΤΟΖ' Ὀλυμπιῳ Κομητι Source: Migne PG 78.396c

That which is set forth in the Divine book, 'Coming, it stopped above the place the child was,' 1 shows most openly to you that this which bore the message of the joyful birth had not the usual and customary way of the stars, for it did not maintain its height, but so that what was sought was able to be found, with a truly new and unusual course, as if a finger, it pointed out that cave and the Lord bearing and venerable manager which was in it. Saint Isidore of Pelusium, Book 1, Letter 378, to Count Olympius 1 Mt 2.9
