Saint Kyaranus asked blessed Coemgenus that they should interchange their vesture, as a sign of everlasting fellowship:  and so they did.  On the following day when the door of the church was opened, the brethren found Saint Coemgenus clad in the vesture of Saint Kyaranus, and Kyaranus wrapped in the vestments of Saint Coemgenus.  The body of Saint Kyaranus was warm, having a ruddy tinge in the face.  Saint Coemgenus pointed out to the monks of Saint Kyaranus the brotherhood and fellowship which he and Saint Kyaranus had established for ever between themselves and their places and their monks; and the brethren who watched that night bore testimony thereto.  When the body of Saint Kyaranus was honourably committed to the ground, Saint Coemgenus returned to his own settlement.” (VSH, i, 248).

In this story we see as before the explanation of a treaty between Clonmacnois and Glendaloch.

The Annals of Clonmacnois narrates the story of the death of Ciaran and the visit of Coemgen, with an interesting additional miracle.  “Dying, he desired his monks that they would bury his body in the Little Church of Clonmacnois, and stop the door thereof with stones, and let nobody have access thereunto until his companion Coemgen had come; which they accordingly did.  But Saint Coemgen dwelling at Glendaloch in Leinster then, it was revealed to him of the death of his dear and loving companion Saint Ciaran, whereupon he came suddenly to Clonmacnois:  and finding the monks and servants of Saint Ciaran in their sorrowful and sad dumps after the death of their said lord and master, he asked them of the cause of their sadness.  They were so heartless for grief as they gave no answer; and at last, fearing he would grow angry, they told him Saint Ciaran was dead and buried, and ordered or ordained the place of his burial should be kept without access until his coming.  The stones being taken out of the door, Saint Coemgen entered, to whom Saint Ciaran appeared:  and [they] remained conversing together for twenty-four hours, as is very confidently laid down in the Life of Saint Ciaran; and afterwards Saint Coemgen departed to the place of his own abiding, [and] left Saint Ciaran buried in the said Little Church of Clonmacnois.  But king Diarmait most of all men grieved for his death, insomuch that he grew deaf, and could not hear the causes of his subjects, by reason of the heaviness and troublesomeness of his brains.  Saint Colum Cille being then banished into Scotland, king Diarmait made his repair to him, to the end [that] he might work some means by miracles for the recovery of his health and hearing:  and withal told Saint Colum Cille how he assembled all the physicians of Ireland, and that they could not help him.  Then said Saint Colum:  ’Mine advice unto you is to make your repair to Clonmacnois, to the place where your ghostly father and friend Saint Ciaran is buried:  and there to put a little of the earth of his grave or of himself in your ears,
