[LEYEN (Marie-Louise de). Devotion to the Heart of Jesus. For the association of the Religious of the Visitation of Strasbourg. Third edition. Strasbourg, Jean François Le Roux, 1754. Small in-8, red morocco, rich lacework of gilt scrolls and fleurons, including a repeated bird's iron and bee's iron, ornate spine, green title page, inner lace, gilt edges (Period binding). A very rare book of devotion to the Sacred Heart published by the Visitation nuns of Strasbourg. Third edition, decorated with a frontispiece by François Aveline and two engravings by Catherine Klauber. This work went through four editions between 1740 and 1767, published by the Strasbourg bookseller Jean François Le Roux. All four are extremely rare, but this one is missing from all French libraries, according to the CCFr, and WorldCat lists only three copies worldwide. Very attractive lace binding in exceptionally fresh condition. The iron with bird traditionally attributed to Derome is repeated six times on each cover. Slight scattered brown spots.
