E00047: Theophylact Simocatta in his History describes the emperor Maurice sleeping in Saint Sophia, hoping to receive divine guidance through a dream, in the autumn of 590, prior to his expedition to Anchialus (eastern Balkans). The next day he attended the Eucharist at the church of *Mary (Mother of Christ, S00033) at Pege, just outside Constantinople. Written in Greek at Constantinople in the early 7th century.

Theophylact Simocatta, History 5.16.7-8

(7.) τυχεῖν δὲ γλιχόμενος καὶ θείας τινὸς ἐποπτίας συστρατευσομένης αὐτῷ ἐπὶ τὸ μέγα τῆς θρησκείας κατεπαννυχίζετο τέμενος τὸ ὑπὸ Ἰουστινιανοῦ ᾠκοδομημένον τοῦ αὐτοκράτορος· ἐς προσηγορίαν δὲ τῆς τοῦ θεοῦ σοφίας τὸ ἱερὸν ἀνατέθειται. (8.) μηδεμιᾶς τοιγαροῦν ὄψεως ἐνυπνίων ἐπιφανείσης αὐτῷ, λιταζόμενος ἅμα τῷ λαῷ εἰς τὴν πρὸ τοῦ ἄστεος τῆς θεομήτορος οἰκίαν διημέρευε μυσταγωγούμενος, καὶ τῆς θεανδρικῆς μετελάγχανε πανδαισίας· ὁ δὲ νεὼς πρὸς τῆς Πηγῇ καταλέγεται.

'(7). Since he [the emperor Maurice] was also eager to obtain some divine guardianship to accompany him on campaign, he spent the night at the great shrine of our religion, the one built by the emperor Justinian: that sanctuary is dedicated to the name of the Wisdom of God. (8.) Accordingly, since no dream vision appeared to him, he spent the day at the house of the Mother of God outside the city, joined in prayer by the people and attending the mysteries, and he partook of the banquet of the Incarnate God [received communion]. The church is known as the one "at the Spring" [Pege].'
