Amador Arraez in one of his dialogues defines mysticism thus: ‘There is a theology called mystic, as being hidden and unintelligible to those who have no part in it. It is attained by much love and few books and with much meditation and purity of heart, which alone suffices for its exercise, and consists mainly in the noblest part of our will inflamed in the love of God, its full and perfect good.’[553] ‘Our will inflamed’: perhaps these words explain the excellence of the style, the intensity and directness, of the writers in this mystic theology. Style, so shy and elusive to Flaubert and his disciples, came unsought to the religious writers of the sixteenth century, because they wrote not with an eye on verbal artifices but out of the fullness of the heart, ‘self-gathered for an outbreak’; and their works can still be read with pleasure by priest and pagan. Mysticism, inherent in the character of the Portuguese, runs through a great part of their literature; we find it, for instance, in the merry poetry of Gil Vicente or in the precious accents of Soror Violante do Ceo. Strength of character, aloofness, rapt enthusiasm, singleness of purpose: these are the qualities of mysticism at its best, and if it also manifests itself in vagueness and confusion, this was not so with the great mystic and religious writers of the golden age of Portuguese literature. To them mysticism was not a cloudy goodness or an abstract perception-dulling humanity, not a mist but a pillar of fire, in the light of which the facts and details of reality stood out the more clearly. But if the intensity of many of the mystics has its natural complement in the fervour and directness of their prose, this was not always the case, and it was not only in profane works that the Portuguese language fell into the pitfalls of _culteranismo_. All the more remarkable is the purity, the exquisite taste, the simplicity and charm of some of the later, seventeenth century, prose. The secret of this prose lay in fact in _culteranismo_ itself, the points and conceits of which were based on a recognition of the value of words. All the _seiscentistas_ set to playing with words as with unset stones of price. The more critical or inspired writers joined in the game but selected the genuine stones, leaving the rest to those who did not care to distinguish between gems and coloured glass.
