Macrina (Μακρίνα) is from the Greek makros (long, great). **Saint Macrina the Younger (c. 330-379)** was the Cappadocian Christian philosopher and elder **sister of Basil the Great and Gregory of Nyssa** — the family that shaped Greek-Orthodox theology. Gregory wrote her biography Life of Macrina as one of the great Christian philosophical dialogues.
**Called "the teacher" (didaskalos) by her brothers.**
Macrina reduces to one — the number of Cappadocian teacher.
