Coma Berenice, the golden hair of Berenice, is a constellation that is situated between Leo and Boötes, that was believed to have been placed by the divine hand of Venus. The constellation is visible throughout the month of May, and is considered the one spot missed by the broom of the old Mother Goose in the rhyme:

There was an old woman tossed up in a basket,

Nineteen times as high as the moon;

And where she was going, I couldn’t but ask it,

For in her hand she carried a broom.

“Old woman, old woman, old woman,” said I,

“O whither, O whither, O whither so high?”

“To sweep the cobwebs out of the sky.

And I’ll return, by and by.

The “19 times as high as the Moon” may also be a reference to the Moon’s metonic cycle.
