about the strait of the Pillars of Hercules, the Mare Externum, or the
British Isles, and the manufacture of tin in them, or even of the
silver and gold mines in Iberia itself, of which historians give long
and contradictory accounts. It was not, let me say, because I
thought these subjects out of place in history that I passed them
over; but because, in the first place, I did not wish to be diffuse, or
distract the attention of students from the main current of my
narrative; and, in the next place, because I was determined not to
treat of them in scattered notices or casual allusions, but to assign
them a distinct time and place, and at these, to the best of my
ability, to give a trustworthy account of them. On the same principle
I must deprecate any feeling of surprise if, in the succeeding
portions of my history, I pass over other similar topics, which might
seem naturally in place, for the same reasons. Those who ask for
dissertations in history on every possible subject, are somewhat like
greedy guests at a banquet, who, by tasting every dish on the table,
fail to really enjoy any one of them at the time, or to digest and feel
any benefit from them afterwards. Such omnivorous readers get no
real pleasure in the present, and no adequate instruction for the
future.
58. There can be no clearer proof, than is afforded by these
particular instances, that this department of historical writing stands
above all others in need of study and correction. For as all, or at
least the greater number of writers, have endeavoured to describe
the peculiar features and positions of the countries on the confines
of the known world, and in doing so have, in most cases, made
egregious mistakes, it is impossible to pass over their errors without
some attempt at refutation; and that not in scattered observations or
casual remarks, but deliberately and formally. But such confutation
should not take the form of accusation or invective. While correcting
their mistakes we should praise the writers, feeling sure that, had
they lived to the present age, they would have altered and corrected
many of their statements. The fact is that, in past ages, we know of
very few Greeks who undertook to investigate these remote regions,
owing to the insuperable difficulties of the attempt. The dangers at
