lynxeyed

In France the strictly repressive policy of the church in the eighteenth century, sometimes bloody and cruel as in the persecution of the Protestants, sometimes minutely vexatious as in the persecution of the men of letters, but always stubborn and lynxeyed, had the natural effect of making it a point of honor with most of those who valued liberty to hurl themselves upon the religious system, of which rigorous intolerance was so prominent a characteristic.
