Ave gracia plena dominus tecum.

The wood-engraver may produce his design in two ways, either by means of black lines on a white ground, or by white designs on a black ground. The two methods are here united, while in the St. Christopher one only (the first) is used. Notice the discreet use of masses of black to give force to the design, and to contrast with the lightness of the other part of the picture. The Annunciation belongs to quite a different school to the St. Christopher.

The other print is of St. Bridget of Sweden (who died in 1373). She is seated at a sloping desk, writing with a stylus in a book. The motto above her head is o brigita bit got für uns ('O Bridget, pray to God for us'). In the left upper corner is a small representation of the Virgin with the Holy Infant in her arms, opposite is a shield with the letters S.P.Q.R. on it, referring to her journey to Rome. In the lower corners are, on the left, the palm and crown of martyrdom; and on the right is a shield with the Lion rampant of Sweden. A pilgrim's hat and scrip hang on a staff behind the Virgin's seat. The print is roughly coloured, evidently by hand.

Many other woodcuts of the same character have been discovered, which are believed to have been engraved in the first half of the fifteenth century. In the Imperial Library at Vienna there is a print of St. Sebastian, bearing the date 1437, which was found in the monastery of St. Blaise in the Black Forest. 'Having visited,' says Herr Heinecken, 'in my last tour a great many convents in Franconia, Suabia, Bavaria, and in the Austrian States, I everywhere discovered in their libraries many of these kinds of figures engraved on wood. They were usually pasted either at the beginning or the end of old volumes of the fifteenth century. These facts have confirmed me in my opinion that the next step of the

engraver on wood, after playing-cards, was to engrave figures of Saints, which, being distributed and lost among the laity, were in part preserved by the monks, who pasted them into the earliest printed books with which their libraries were furnished.' Herr Heinecken possessed more than a hundred of these pictures of Saints. There can be little doubt they were produced in the monasteries and convents, and distributed to the people, especially in the processions of the Church, as aids to devotion. Among the thousands of monks who lived in the fifteenth century there must have been many men who, like Fra Angelico, were gifted with sufficient artistic taste to enable them to draw and engrave such a picture as the St. Christopher.
