The 12th-century carol beginning ``Jesus, our brother, kind and good'' provides the text for this setting of the Christmas story in a large, square format whose ample double spreads present panoramic scenes focusing especially on the animals coming to the manger. Deftly applying her bold line and large areas of lucid, serene color, Chamberlain creates art of deceptive simplicity that is sure to have broad appeal. Music included. (Picture book. 2-8)
