Venerable Eudokia (in monasticism Euphrosyne), Grand Duchess of Moscow - Troparion & Kontakion
Troparion — Tone 8
By a flood of tears you made the desert fertile, / and your longing for God brought forth fruits in abundance. / By the radiance of miracles you illumined the whole universe! / O our holy mother Euphrosynē, pray to Christ our God to save our souls!
