Noble women became patrons of art, particularly that branch cultivated with most success in the decline of the rest--miniature painting upon parchment. From being merely ornamental this became a necessity in manuscript books of devotion, and the brilliant coloring and delicate finish of the illuminations were often owing to the touch of feminine hands. The inmates of convents and monasteries employed much time in painting and ornamenting books, in copying the best works of ancient art, and in painting on glass; the nuns especially making a business of copying and illuminating manuscripts. Agnes, Abbess of Quedlinberg, was celebrated as a miniature painter in the twelfth century, and some of her works have survived the desolation of ages. “The cultivators of this charming art were divided into two classes--miniaturists, properly so called; and miniature caligraphists. It was the province of the first to color the histories and arabesques, and to lay on the gold and silver ornaments. The second wrote the book, and the initial letters so frequently traced in red, blue, and gold: these were called ‘Pulchri Scriptores,’ or fair writers. Painting of this description was peculiarly a religious occupation. It was well suited for the peaceful and secluded life of the convent or the monastery. It required none of the intimate acquaintance with the passions of the human heart, with the busy scenes of life, so essential to other and higher forms of art.” The labors of nuns in ornamental work in the Middle Ages were not confined to illuminating and miniature painting; but it is not our province to enumerate the products of their industry, nor to chronicle the benefits they conferred on the sick and poor. The fairest princesses did not disdain to work altar-pieces, and to embroider garments for their friends and lovers. In the commencement of the fourteenth century a female painter, named Laodicia, lived in Pavia, and Vasari mentions the Dominican nun, Plautilla Nelli. “In 1476, Fra Domenico da Pistoya and Fra Pietro da Pisa, the spiritual directors of a Dominican convent, established a printing-press within its walls; the nuns served as compositors, and many works of considerable value issued from this press between 1476 and 1484, when, Bartolomeo da Pistoya dying, the nuns ceased their labors.” THE FIRST SCULPTRESS. Germany had the honor of producing the first female sculptor of whom any thing is known--Sabina von Steinbach, the daughter of Erwin von Steinbach, who in that wonderful work, the cathedral of Strasburg, has reared so glorious a monument to his memory.
