The Spartan lying on his back is most likely dead, possibly from a sword thrust into his back during the frenzy of mass combat. However, no wounds are visible in his current posture. After the battle, once the Spartans have been slaughtered, his death must be verified, along with the deaths of the other fallen studs. It is suspicious that the warrior clutches his weapon. I am mindful that like his dead comrades, he is strong and athletic. With one of his knees bent and his foot flush with the ground, he could be poised to spring up suddenly and take me and a few of my men out before he is inevitably put down and added to the body pile. So, to answer the question, in an abundance of caution, I would shoot an arrow into his chest from a short distance and sink the shaft into his heart. If he responds to the strike, we will know he was mimicking death in the ruse of the possum, but it will not matter. He will go to his reward with a skewered pump. If he was indeed dead all along, nothing more than a single arrow has been wasted on him. I might even be able to use the shaft again, after I pull it from between his ribs. I admire this Spartan and his manly death. I will claim trophies from his handsome corpse. Of course, his weapon and various items from his gear are worthy souvenirs. I am inclined also to cut off one or more parts of his anatomy and take them with me. Many of my comrades who engage in this practice regularly sever an ear from the enemy dead. Others slice off the nips of particularly worthy specimens. The disks of chest flesh make impressive amulets once they have been tanned. As for me, I will investigate possibilities inside his codpiece.
