The two years following his marriage (1860-1862) were amongst the most prolific of Rossetti's life both in ideas and invention. Besides "Cassandra" he planned the composition for a large picture which was commissioned but never finished, representing Perseus with the Medusa's head; and he made the first pencil studies for his famous "Beata Beatrix." With 1862 is associated the water-colour, "Bethlehem Gate." It is also about this time (1861-1862) that the now famous firm of Morris, Marshall, Faulkner & Co. was established with the co-operation of William Morris, Faulkner, Burne-Jones, Madox Brown, Webb, and others as active members. The idea of the commercial attempt on the artistic lines to reform the art of decoration and furniture-making was, says Mr. Mackail, largely due to Madox Brown, but perhaps more to Rossetti, who, in spite of his artistic qualities, was a very good business man and had the scent of a trained financier for anything likely to pay. The little band of original artists and designers took in hand tapestry, furniture, wall papers, stained-glass, and later on, carpet weaving and dyeing. The terms under which they worked were very simple. Each member was to be paid for the work commissioned by the firm, and the profits were to be divided in a proper ratio at the end. The new firm had plenty to do owing to the demand for ritual decorations caused by the Anglo-Catholic movement. Amongst the first commissions were those for adorning two new churches then being built--St. Martin-on-the-Hill, Scarborough, and St. Michael at Brighton. For the first one Rossetti made a design for two pulpit panels and several windows. In dealing with stained-glass Rossetti who was specially gifted as a decorator, understood his medium, and in making his design took into account all the limitations of the material. He did not seek to paint a picture on glass, but maintained that idea of a mosaic of coloured-glass that is seen to so much advantage in the early _vitraux_.
