The '''Life-Giving Spring''' or '''Life-Giving Font''' of the [[Theotokos|Mother of God]] (in Greek: Ζωοδόχος Πηγή) is both the [[feast day]] of [[w:Church of St. Mary of the Spring (Istanbul)|a historic church]] just west of Constantinople in [[w:Balıklı, Istanbul|Valoukli]], and an icon of the [[Theotokos]].
The Life-Giving Spring ''[[Icon]]'' of the Most Holy [[Theotokos]] is commemorated by the [[Orthodox Church]] on [[April 4]]. The [[feast day]] of the Life-Giving Spring itself is commemorated on [[w:Easter Friday|Bright Friday]] of each year (the Friday following [[Pascha]]), being the only feast day which may be celebrated during [[Bright Week]].
The first is recorded by the prominent Byzantine scholar [[w:Procopius|Procopius of Caesarea]] (flourishing ca.500-565).<ref group="note">The 11th century Byzantine historian [[w:George Kedrenos|George Cedrenus]] also mentions this version.</ref> In this version, the Emperor [[Justinian]] was out hunting when he came upon a small [[chapel]] in a beautiful wooded area, surrounded by a large crowd of people and a priest in front of a spring. Inquiring about this site, he was told that this was the “source of miracles”. He at once ordered that a magnificent church be built there, utilizing materials that had remained after the erection of the [[Hagia Sophia (Constantinople)|Hagia Sophia]].<ref name="JANIN"/> The church was erected in the last years of his reign, ca.559-560, near the holy spring.<ref group="note">In this context, "Holy Spring/Holy Font/Holy Source" becomes synonymous with the Greek: ἁγίασμα, ''hagiasma''; Lit.: 'sanctuary'.</ref> After the erection of the sanctuary, the Gate that was situated outside the [[w:Walls_of_Constantinople#Theodosian_Walls|walls of Theodosius II]] was named by the Byzantines ''Gate of the Spring'' (Greek: Πύλη τῆς Πηγῆς).<ref>Wolfgang Müller-Wiener (in German).
