Arma virumque cano Virgil sang, or professed to sing, at the start of his epic, and one may reformulate the import of his programmatic words to fit a new context. Obtaining weapons he can call his own is very often a key moment near the start of the career of a folk-tale hero. And very often it is the hero's mother who equips him with them. Paradoxically, this truth may be confirmed, e contrario, by reference to the Welsh story of Lleu Llaw Gyffes from the Mabinogion, for, in that narrative, the hero's mother Aranhry seeks to thwart at its inception the career of her son – whom she had exposed, since his very existence causes her so much embarrassment – by placing a Destiny or interdiction upon him: he will never bear arms unless and until she herself bestows them. The ban is circumvented by a cunning ruse: the magician Gwydion disguises her son and himself as peripatetic bards, in which capacity they are entertained in Aranhry's castle. When Gwydion conjures up a phantom army and fleet to besiege the citadel, the alarmed Aranhry is all too ready to bestow weapon and armour on the younger of her two guests – only to find the army vanished and her own son in possession of the arms she had sworn he would not bear.
