Origin

The story of Eleni

Eleni keeps 21 May — Saints Constantine and Helen, honoured together by the Church as Equals-to-the-Apostles.

The name is old and its origin is uncertain — a point worth keeping honest rather than smoothing over. Ἑλένη is Ancient Greek, usually traced to the Indo-European root *swel- — “to shine, warm” — and originally, it seems, the name of a solar deity. But no derivation is settled, and we would rather say so.

“Of uncertain origin — from a root that means to shine.”
