The story of Kassia
Kassia is said to have been a candidate in a bride-show for the emperor Theophilos, and to have lost it by answering back — he remarked that woman is the source of evil and she replied that woman is also the source of better things. She founded a convent and wrote hymns; her setting for Holy Wednesday is sung every year in Orthodox churches, which makes her the only woman composer in that living repertoire.

Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method
