The Old Woman & the Wine-Jar

You must know that sometimes old women like a glass of wine. One of this sort once found a Wine-jar lying in the road, and eagerly went up to it hoping to find it full. But when she took it up she found that all the wine had been drunk out of it. Still she took a long sniff at the mouth of the Jar. ‘Ah,’ she cried,

‘What memories cling ‘round the instruments of our pleasure.’

The Cat-Maiden

The gods were once disputing whether it was possible for a living being to change its nature. Jupiter said ‘Yes,’ but Venus said ‘No.’ So, to try the question, Jupiter turned a Cat into a Maiden, and gave her to a young man for a wife. The wedding was duly performed and the young couple sat down to the wedding-feast. ‘See,’ said Jupiter, to Venus, ‘how becomingly she behaves. Who could tell that yesterday she was but a Cat? Surely her nature is changed?’

‘Wait a minute,’ replied Venus, and let loose a mouse into the room. No sooner did the bride see this than she jumped up from her seat and tried to pounce upon the mouse. ‘Ah, you see,’ said Venus,

‘Nature will out.’
