Scott's rendering of the cup's inscription made him believe that it was a Hebridean drinking cup, dating from the year 993. Scott also declared that Macleod tradition had it that the cup had once belonged to "Neil Ghlune-Dhu, or Black-knee. But who this Neil was, no one pretends to say". In about 1851, Sir Daniel Wilson documented the cup in his "The Archaeology and Prehistoric Annals of Scotland", following along the same lines as Scott. Wilson made only a few minor edits to Scott's rendering of the Latin inscription, but at the time he had not seen the cup. After certain correspondence and the aid of William Forbes Skene, Wilson was able to examine the cup in person and later amended his analysis. His subsequent rendering of the inscription was vastly different from Scott's, and Wilson concluded that the cup was a product of Irish craftsmanship, rather than of Scottish origin. Wilson's new rendering of the inscription had the cup belonging to a "Katharina nig Ryneill"; and he considered that the John, son of the Maguire, who was mentioned in the transcription, was the same as the one mentioned in the Annals of the Four Masters in the year 1484. Wilson stated that this John died in 1511, and that his wife was unknown; but that a Catherine, who was the daughter of MacRannal, was married to a Maguire, and her death is mentioned in the year 1490.
