The following verses from a modern poet happily describes one of these incidents-- "'O, lady fair! I have yet a gem, Which a purer lustre flings Than the diamond flash of the jewelled crown On the lofty brow of kings; A wonderful pearl of exceeding price, Whose virtue shall not decay; Whose light shall be as a spell to thee, And a blessing on thy way.' "The lady glanced at the mirroring steel, Where her youthful form was seen, Where her eyes shone clear, and her dark locks waved Their clasping pearls between; 'Bring forth thy pearl of exceeding worth, Thou traveller grey and old; And name the price of thy precious gem, And my pages shall count thy gold.' "The cloud went off from the pilgrim's brow, As a small and meagre book, Unchased with gold or diamond gem, From his folding robe he took: 'Here, lady fair, is the pearl of price; May it prove as such to thee! Nay, keep thy gold--I ask it not-- FOR THE WORD OF GOD IS FREE.' "The hoary traveller went his way, But the gift he left behind Hath had its pure and perfect work On that high-born maiden's mind; And she hath turned from her pride of sin To the lowliness of truth, And given her human heart to God In its beautiful hour of youth. "And she hath left the old grey walls, Where an evil faith hath power, The courtly knights of her father's train, And the maidens of her bower; And she hath gone to the Vaudois Vale, By lordly feet untrod, Where the poor and needy of earth are rich In the perfect love of God!"
