The Window of The Institution of The Eucharist is the second window on the left
if you are facing the altar. The large center medallion references the scripture
passage of Mark 14:22-26 in which we hear the words of institution: "And as
they were eating He took bread and blessed and broke it and gave it to them and said,
'Take, this is my body.' And He took a cup and when He had given thanks, He gave it to
them and they drank all of it and He said to them, 'This is my blood of the New Covenant
which is poured out for many. Truly I say to you, I shall not drink again of the fruit of
the vine until that day when I drink it new in the
Pope John Paul II also name The Institution of the Eucharist as the 5th of the new Luminous Mysteries of the Rosary.

All the saints and depictions in this window deal with devotion to the Eucharist and the sacrament itself... Surrounding the centerpiece, clockwise, beginning at the top is Our Lady of Guadalupe, Patroness of the Americas:

During a walk from his village to
the city on the early morning of December 9, 1531, Juan Diego saw a vision of the Virgin
Mary - a young girl of fifteen to sixteen, surrounded by light- at the Hill of Tepeyac.
Speaking in Nahuatl (the native language), the Lady asked for a church to be built at that
site in her honor. When Juan Diego spoke to the bishop, Juan de Zunarraga , he was asked
for miraculous sign to prove his claim. The Virgin asked Juan Diego to gather flowers at
the top of Tepeyac Hill, even though it was winter when no flowers bloomed. He found there
Castilian roses, gathered them, and the Virgin herself re-arranged them in his cloak. When Juan Diego presented the roses to Zumárraga,
the image of the Virgin of Guadalupe miraculously appeared imprinted on the cloth of
Diego's cloak.

Directly below St. Stanislaus on the lower right is St. Clare of Assisi

Saint Clare of Assisi was born
Chiara Offreduccio on July 16, 1194 and was one of the first followers of St. Francis.
She founded the Order of Poor Ladies, a monastic order for women in the Franciscan
tradition. Following her death, the order she founded was renamed in her honor as
the Order of Saint Clare, commonly referred to today as the Poor Clares.
The medallion below the main depiction is of children receiving First Holy Communion...
Pope Benedict XVI has written, "I also recommend that, in their Catechetical training, and especially in their preparation for First Holy Communion, children be taught the meaning and the beauty of spending time with Jesus, and helped to cultivate a sense of awe before his presence in the Eucharist."
Moving clockwise - on the lower left is St. Hyacinth.

Saint Hyacinth, Swiety Jacek,
Jacek Odrowaz, was born in 1185 in Upper Silesia. A Doctor of Sacred Studies and a priest,
he worked to reform convents in his native Poland. While in Rome, he witnessed a miracle
performed by St. Dominic, and became a Dominican. He brought the Dominican Order to
Poland, then evangelized throughout Poland, Sweden, Norway, Denmark, Scotland, Russia,
Turkey and Greece.
And completing the circle on the upper left is St.
Tarsicius...

Tarsicius was an acolyte or perhaps a deacon in Rome. He was beaten to death on the Appian Way by a mob while carrying the Eucharist to some Christians in prison. Tarsicius is the patron of first communicants and altar servers.
The Institution of the Eucharist window has the white background with gold crosses. This is one of two alternating backgrounds in all the large windows. The window was a gift of Walerjan Sikorski.
