On this sheet of tracing paper Sandys has copied the top right section of the border running round a page in the 'Jerome Epistulae,' an illuminated manuscript. The manuscript is no. 3109 in the Harley Collection, a group of illuminated manuscripts which were given to the British Library but kept at the British Museum in the nineteenth century. This manuscript is thought to have been made in Rome in the last quarter of the fifteenth century, possibly by the artist Andrea da Firenze. The border has been copied from the page decorated with an illuminated letter 'I' and depicting St. Jerome writing at a desk in a luxurious garden. Sandys has faithfully copied the red, green and blue colouring and added orange where the original was touched with gold.
