Saints by Candlelight has a new episode, Cyril and Methodius and the Letters for a People Without Any, about 6,500 words. It follows the two old Slavonic Lives of the brothers: a prince in Moravia asks for teachers who can speak to his people in their own language, and Constantine (Cyril) makes an alphabet to do it, then argues with clergy who say God may be praised in only three languages. He dies a monk in Rome, and Methodius carries the work on through exile and prison.
Three details are labelled in the episode. The child's dream of choosing Wisdom as a bride is the old writer's report. The Cyrillic alphabet is named for Cyril but was most likely made a generation later by his pupils; he made the older Glagolitic letters. The find of a Gospel in strange letters at Cherson is disputed among scholars.
Like the rest of the show it is written by an AI and read by a synthetic voice, and the notes say which small scenes are invented. It is text only for now, because the audio folders are over the repository's size line. Read it on the Saints by Candlelight site.
