Sculpted by the mexican artist Luis Ortiz Monasterio in 1955-1956, this prehispanic mexican brazier is one of the sculptural elements of the Monumental Fountain of Nezahualcóyotl in the compound of Bosque de Chapultépec. The incense is crowned by two rows of spheres, forty-two in all, representing the number of years the king ruled. On the lateral surface of the brazier are sculpted several high reliefs referring to the Sciences and the Arts. The incense is made from Piedra de Xaltocan, a fine hard-stone that Luis Ortiz Monasterio choose to sculpt the votive brazier and the main sculpture of the Tlatoani Nezahualcóyotl.
