" Luck sets its stamp upon a man outwardly. Whence had the Northmen their
keenness of vision, which enabled them to apprize a man at a glance? At the
first meeting they would say either: he is a man promising luck and
honour (sæmligir and hamingjusamligr), one luck is to be expected
of(giptuvænligr), or: he bears the mark of unluck (úgiptubragð). Partly on the
strength of intuition, as we say — or, as the ancients put it, because the mind of
the beholder told him what to think of the stranger, — but partly on external
criteria; luck manifested itself openly in the newcomer's mien, gait, behaviour,
bearing, and not least in his well-nourished appearance, his health, his dress,
and his weapons. Only a family of wealth and speed is able to send its
youngling out in many-coloured clothes and with a splendid axe, an “heirloom”
of a weapon. "
