The scene is at night.

In the center foreground, a very large tan dog with long floppy ears and a square head lies on the ground dead.

Behind the dog's carcass, Cuchulain stands.  His left foot rests on the dog's shoulder, Cuculain's weight on the right foot.  Cuchulain wears a brown tunic belted at the waist.  On his feet are leather laced boots over white mid-calf stockings.  He wears a light blue cape over his shoulders. In his right hand is a spear.  The spear's point rests by the dog's nose.

In the backrgound, stands the stone wall of a castle with one narrow, slotted window.  In the doorway stand the king and two princes, each wearing a thin gold band around their heads, and each dressed in tunics reaching mid-calf.  Behind them can be seen the tongues of flame from torches lighting the castle.
