This illustration for a bookplate was commissioned by a friend for his wife Sarah.  Her saint is Seraphim of Sarov.

Troparion of St. Seraphim, Tone 4
Thou didst love Christ from thy youth, O blessed one,
and longing to work for Him alone thou didst struggle in the wilderness with constant prayer and labor.
With penitent heart and great love for Christ thou wast favored by the Mother of God.
Wherefore we cry to thee:
Save us by thy prayers, O Seraphim our righteous Father.
