Zeus was drunk and happy.
“You women get more from Aphrodite than we do”, he said to Hera.
She denied it and both agreed to ask Tiresias his opinion. That wise man knew both sides for he had been made a woman for seven years for disturbing a coupling.
“Woman”, said this judge, “takes more. Of ten parts, man gets only one.”
For revealing this secret, Hera struck him blind. Zeus took pity on him and gave him the power to see the future.
The power of insight and the danger of women, all in one tale.
