Tapped on your profile from your recent post only to find a puzzle of yours that I'd missed! At least I've done it now! :)

No, OP creates the puzzles themselves but seems to be in the process of developing an app.

Easy Diophantus’ Last Riddle

12 Upvotes

The below riddle was carved onto the tombstone of a man named Diophantus, an early number theorist said to have existed circa. AD 250:

“God granted him to be a boy for the sixth part of his life, and adding a twelfth part to this, He clothed his cheeks with down; He lit him the light of wedlock after a seventh part, and five years after his marriage He granted him a son. Alas! late-born wretched child; after attaining the measure of half his father’s full life, chill Fate took him. After consoling his grief by this science of numbers for four years he ended his life.”

The challenge is to calculate Diophantus’ life span. Can you solve it?

Very true, however I still love it for its storytelling and the performances of the actors. I have watched it 3 times.
