What were the words spoken when excalibur the sword was plunged into the stone?
According to the medieval story of Merlin attributed to Robert de Boron, the sword was plunged into the stone several times after Arthur first drew it forth, and each time only Arthur could draw it forth. But no words are recorded as being spoken at any of the times that the sword was again placed in the stone, either in Robert de Boron’s Merlin or in any works based on it, like Sir Thomas Malory’s “Le Morte d’Arthur”. Possibly in some modern retelling there are some words spoken, but modern retellings are so many and often so different from one another, that perhaps you should indicate which one you are referring to.
