Anonymous, Greek Anthology 14.6
Book 14 of the Greek Anthology comprises epigrams that are puzzles of various sorts. Here’s a mathematical one. Answers on a postcard please!
“ὡρονόμων ὄχ’ ἄριστε, πόσον παρελήλυθεν ἠοῦς;”
“ὅσσον ἀποιχομένοιο δύο τρίτα, δὶς τόσα λείπει.”
‘Best by far of sundials, how much of the day has gone by?’ ‘Two thirds of what has passed – twice that much is left.’
