There is little evidence of the imposition of fines as ecclesiastical penalties; but there are references to the practice in the epistles of St Gregory the Great, notably in his instructions to St Augustine.
References to original papers indicate further sources of information.
I would reiterate the earlier suggestion that references be implemented.
Further references of great value will be found in the works of Bateson and Pearson referred to above, and in the annual volumes of the Zoological Record, particularly under the head " General Subject."
Himilco, a contemporary of Hanno, was charged with an expedition along the west coast of Iberia northward, and as far as the uncertain references to this voyage can be understood, he seems to have passed the Bay of Biscay and possibly sighted the coast of England.
