one of the immortals in Borges story.
Fishburn and Hughes: "'Argos…This dog lying in the manure' (`Este perro tirado en el estiércol’). In the Odyssey, Odysseus' faithful dog, who is the first to recognise him on his return to Ithaca. CF 190: The passage describes how Odysseus had raised and trained the dog but never hunted with him before leaving for the Trojan war. Nineteen years later Argos is lying 'on the deep pile of dung' which is to be used for manure: 'Now, as he perceived that Odysseus had come close to him, / he wagged his tail, and laid back both his ears...' and died (Odyssey 17. 290-327)."
