THE SHIELD OF MANANNAN
247
great hero who carried it was Fionn mac Cumall, and whenever he went into battle the shield would thunder like a great wave crashing against cliffs, bringing fear to Fionn's enemies; but to his own ears it sounded like a very sweet war-song. After the death of Fionn no other king or hero bore the enchanted shield, for it disappeared; but the legend says that when St. Patrick came to Ireland he found it and caused it to be burnt.
This I do not think is likely. I imagine Manannan took the shield back to his own world, knowing that when Fionn passed away the long line of great heroes and warriors had come to an end.
