In a not-so-distant future when lions are extinct Jachin-Boaz, a middle-aged mapmaker, leaves home with a wonderful map that was to tell his son where to find everything. The angry son, Boaz-Jachin, goes to the ruins of a palace at Nineveh and performs a series of rituals before the wallcarving of a great lion dying on the spear of an ancient king. Called to life, the lion sets out on the father's tracks and the son follows.
