From another thread:
This version of the image of Our Lady of Guadalupe was painted by a Greek Orthodox monk:
I even have a Russian Orthodox icon catalog that used to sell this icon.
There are several tropars and kondaks written for the feast of Our Lady of Guadalupe. Here is an example:
The peasant joyfully held open his cloak to contain roses growing out of season, most Holy Mother, and he quickly carried the flowers to his bishop. In just such a way, you joyfully opened yourself to contain the Babe, growing before you had known man. The flowers carried by the peasant formed an image of you on his cloak. The Child carried by you formed you into an image of His grace. Therefore we cry out to you, Rejoice, most holy Mother of God.
When Adam and Eve sinned, they were promised that one would come that would crush the serpent. The serpent fled to the west, into a land of people that did not know God. But the serpent was not hidden from the wrath of God, and the Child that you so lightly carried in your arms was too heavy for the serpent’s skull. Therefore, we cry out to you, pray for us, most holy Theotokos.
Another Kontakion, Tone 8. Special melody: Ti hypermacho:
The precious mantle * of your Protection * which once pious Andrew saw * as you revealed yourself * to him praying * in the Emp’ror’s city * is now seen by all the faithful in the Tilma of Tepeyac * from which falls God’s grace * like a shower of roses from paradise * that will crush the ancient serpent’s head * as we all sing to you: * Rejoice, O Virgin of Guadalupe.
Since an old post of mine has been re-posted, I thought I should reply...
According to information posted on another forum, the icon was painted by an Orthodox monk by the name of Fr. Nathaniel from Ohio of the Greek Orthodox Archdiocese. I am assuming it is the late Fr. Nathaniel from St. Gregory Palamas Greek Orthodox monastery in Akron, Ohio.
The icon was available for purchase from the catalogs published by the now closed Christ of the Hills Monastery in Blanco, Texas.
As for the troparion and kontakion, these were composed and posted online by a one Bishop Basil of the Life-Giving Fountain Orthodox Mission, a non-canonical Orthodox community.
In addition to the troparion and kontakion composed by the Byzantine Catholic Metropolia mentioned by Deacon Lance, the Ukrainian Catholic monks of Holy Transfiguration Monastery in Ukiah, CA also composed their own office for the feast of Our Lady of Guadalupe which they celebrate at their monastery:
TROPAR (TONE 1)
O Holy Lady, Virgin of Guadalupe, Mystical Rose and Queen of America,/you came to bring the peace of Jesus and to take our cares into your loving Heart./ Therefore we venerate your glorious image/ as a sign from God Himself/ that you protect us and pray for our souls.
KONDAK (TONE 4)
O Virgin Mother, your mantle covers all the Americas/ and your miraculous image proclaims the glory of God./ Make our wintery hearts blossom with roses of repentance and love,/ and allow us to place them in the crossing of your arms/, that you may carry them to Christ our God/ and beseech Him to grant us His great mercy.
If I remember correctly, the monks of Holy Resurrection Romanian Catholic Monastery in now Saint Nazianz, WI composed an office for the feast of Our Lady of Guadalupe when they were still under the then Eparchy of Van Nuys.
Here is video of the monks celebrating their First Vigil Service at their new monastery in Saint Nazianz: http://www.youtube.com/watch?v=CWFoy0J-G5M&feature=youtube_gdata_player
At minute 1:06, you will see an image of Our Lady of Guadalupe enshrined in their chapel.
