If you ever think Mythology is boring...
Just remember that Cerberus, the hell-hound and guard dog of the underworld, comes from the root Indo-European word Kerberos, which evolved into the Greek word, Kerberos, which got changed into Cerberus when it went from Greek to Latin
Kerberos means "spotted"
that's right
Hades, Lord of the dead, literally named his pet dog Spot
Hades stared at the small animal staring at him. It really wasn't that small. It was a hellhound, but a baby one. He wondered to name it.
"What about 'The Void that will soon Consume the Mortals'?" Alecto offered.
"No no. Too long." Hades complained.
"Oh oh how about 'Death Puppy'?" Tisiphone asked.
"But what about when he's not a puppy? What then?" Megaera argued. "You should name it Spot! Its a classic!"
"Gods Megaera!" Alecto screeched. "Spot is such a stupid name-"
"Wait." Hades said. "Spot. I like it. But it seems a little sweet. Is there a way we could make it more dangerous?"
Megaera looked and Tisiphone, and Tisiphone at Aleco. Meanwhile, Alecto looked at Megaera.
"Well Lord, through a few translations, Cerberus means Spotted." Tisiphone said.
"Perfect!" Hades exclaimed. He turned towards the little puppy.
"Hello Cerberus."
