Holy Monastery Dionysiou - Panagia of the Salutations the Myrrhgusher
According to an inscription on the back of this icon, it was given as a gift to Saint Dionysius, founder of the Holy Monastery of Dionysiou on Mount Athos, by Emperor Alexios Komnenos, upon his visit to Trebizond in Asia Minor. According to Holy Tradition, this is the same icon that Patriarch Sergius processed around the walls of Constantinople in 626 A.D. during the reign of Emperor Heraclius. At that time Constantinople was attacked by the Persians and "Scythians" (Avars and Slavs) but saved through the intervention of the Most Holy Theotokos. A sudden hurricane dispersed the fleet of the enemy, casting the vessels on the shore near the great Church of the Theotokos at Blachernae near the Golden Horn. The people spent the whole night in front of this icon thanking her for the unexpected deliverance. In memory of this event the Akathist Hymn is chanted in the Orthodox Church.
In 1592 Algerian pirates stole the icon, but after a fierce storm, a frightening dream, and a great miracle, the leader of the pirates was forced to return it to the monastery. They had hid it in a chest, but the icon shattered it and it was drenched in myrrh. Because of this miracle, some pirates repented and entered the monastery to become monastics.
In 1767 certain theives from Dalmatia stole the icon, and upon their return to Dalmatia were apprehended by Greek shepherds who took the icon and brought it to Skopelos. On Skopelos island the Greek community leaders elected by the Turks, known as Dimogerontes, denied to the Dionysian monks from Mount Athos the return of the icon when they came to request its return. After three months Skopelos was punished by a plague which brought great tragedy to the island, and the Dimogerontes repented and had the icon returned to Dionysiou Monastery and also established a metochion for the monastery on the island.
The icon is small and darkened by time. It is housed in a chapel dedicated to the icon at Dionysiou Monastery where the Akathist Hymn is sung daily.

Kontakion (Plagal of the Fourth Tone)
O Champion General, we your faithful inscribe to you the prize of victory as gratitude for being rescued from calamity, O Theotokos. But since you have invincible power, free us from all kinds of perils so that we may cry out to you: Rejoice, O Bride unwedded!
Theotokion (Tone Three)
Seeing the beauty of your Virginity, and how resplendently shone forth your chastity, amazed was Gabriel who cried to you thus, O Theotokos: What shall I present to you as a worthy encomium? What shall I address you as? At a loss and perplexed am I. As ordered, therefore, thus do I shout to you: Rejoice, O Maiden who are full of grace!
