1) Purify the Altar area.
2) Take the barley and say, “As it was done in ancient times. I purify and cleanse this altar with this barley. With this barley I purify this altar and space so that I may give offerings, libations, and speak with glory and respect the gods of Mt. Olympus.”
3) Light a candle and say a hymn to Hestia.
Hestia, you who guard the sacred shrine of the Lord Apollon. The far-darter at goodly Pathos. With soft oil dripping ever from your locks. Come now to this house, come having one mind with Zeus the all wise-draw near, and with all bestow favor upon my song.”
Prayer to Hestia
Hestia, gracious goddess who sits at the heart of each home, who lives in the heart of each one who reveres you, each one who holds you dear, each one who turns to you for strength and harmony.
Hestia, goddess most needful, goddess most serene, goddess most esteemed, the heart of the city is yours as well, great goddess; within your realm are those who serve the state, who work for all the good of all–your blessings fall on the honest, goddess, your wrath on the corrupt, on those who betray their trust for gain. Defender of the householder, guardian of the hearthfire, Hestia, I praise and honor you.
4: Let Asklepius know that your here, include any offerings and libations that you’ve done, and let him know why your here.
5: Say a invocation to Asklepios
I call to Asklepios, finest of physicians, son of far-shooting Apollo, known as Paean, student of immortal Cheiron, wisest of centaurs, counselor of heroes. In Epidaurus were you well honored; many were the supplicants who prayed to you for healing, many were the cures granted, the petitions answered, the heartfelt thanks received by you, O kindly Asklepios. Throughout the land were you known, did men and women beg your blessing; your altars overflowed with their grateful offerings, your temples sheltered those who sought your favor in dreams. Asklepios, friend of the people, friend of the suffering, soother of pain, healer of ills, restorer of health, good-hearted Asklepios, I call to you.
6: Say a prayer to Asklepios
All praise to skillful Asklepios, son of Apollo and bright Koronis, kind-hearted god, friend of men and women. Your gentle touch
eases our pain, oh god, your firm hand guides or restoration; you teach us to live well, to care for ourselves, to seek the wisdom of
Hygeia, your beloved daughter, good and knowing goddess who turns the minds of men toward wholesome food and drink, and
healthful pursuits. Nimble-fingered one, quick-witted one, by your might does the broken bone set, the torn flesh mend, the
damaged soul heal. With your help do we bear any hurt, do we suffer any malady, do we battle any affliction, with strength of will
and with steadfast heart: Asklepios, father of physicians, helper of humanity, I praise you, I honor you, I thank you for your gifts.
7: Sing a Hymn to Asklepios
I begin to sing of Asclepius, son of Apollo and healer of sicknesses. In the Dotian plain fair Coronis, daughter of King Phlegyas, bare him, a great joy to men, a soother of cruel pangs.
 And so hail to you, lord: in my song I make my prayer to thee!
8: Say your own prayer, if your in need of Asklepios help.
9: Burn offering of incense to him.
10: Offer food to him, make sure that it’s wholesome and good for you.
11: Pour out libations to him.
12: End the ritual by saying, “Hestia, goddess of home and hearth, to you I offer last of all as a pious mortal should. Tend to those whom I love and guard the houses of the pious. As the gods will it, so it shall be.”
It is so!
Dump the entire container that you’ve poured your wine or grape juice into outside and then that ends it.
