text_A: Young Fionn, still known by his boyhood name Demne, met the poet Finn Éces (Finnegas), near the river Boyne and studied under him. Finnegas had spent seven years trying to catch the salmon that lived in Fec's Pool () of the Boyne, for it was prophesied the poet would eat this salmon, and "nothing would remain unknown to him". Although this salmon is not specifically called the "Salmon of Knowledge", etc., in the text, it is presumed to be so, i.e., the salmon that fed on the of knowledge at Segais. Eventually the poet caught it, and told the boy to cook it for him. While he was cooking it, Demne burned his thumb, and instinctively put his thumb in his mouth. This imbued him with the salmon's wisdom, and when Éces saw that he had gained wisdom, he gave the youngster the whole salmon to eat, and gave Demne the new name, Fionn.
text_B: Does this passage lead the reader to believe that anyone who ate part of the Salmon of Knowledge, and not just the poet in the prophesy, could gain its wisdom?
NO.
