Duncan: This castle hath a pleasant seat; the air Nimbly and sweetly recommends itself Unto our gentle senses. Banquo: This guest of summer, The temple-haunting martlet, does approve By his lov’d mansionry that the heaven’s breath Smells wooingly here: no jutty, frieze, Buttress, nor coign of vantage, but this bird Hath made his pendent bed and procreant cradle: Where they most breed and haunt, I have observ’d The air is delicate.
