Quote context

- It is a planet with an ancient and mysterious history in which the most mysterious figures are those of the Great Circling Poets of Arium.

- It was of course a descendant of these eccentric poets who invented the spurious tales of impending doom which enabled the people of Golgafrincham to rid themselves of the useless third of their population.
