‘We were not fearful of men’s judgment in those days,’ he answered. ‘Now mark me closely, good people, for what follows will be to you, though not to me, remarkable. When I reached the empty Mill, old Saturn, low down in the House of the Fishes, threatened the Sun’s rising-place. Our Lady the Moon was moving towards the help of him (understand, I speak astrologically). I looked abroad upon the high Heavens, and I prayed the Maker of ’em for guidance. Now Mars sparklingly withdrew himself below the sky. On the instant of his departure, which I noted, a bright star or vapour leaped forth above his head (as though he had heaved up his sword), and broke all about in fire. The cocks crowed midnight through the valley, and I sat me down by the mill-wheel, chewing spearmint (though that’s a herb of Venus), and calling myself all the asses’ heads in the world! ‘Twas plain enough now!’

‘What was plain?’ said Una.

‘The true cause and cure of the plague. Mars, good fellow, had fought for us to the uttermost. Faint though he had been in the Heavens, and this had made me overlook him in my computations, he more than any of the other planets had kept the Heavens—which is to say, had been visible some part of each night wellnigh throughout the year. Therefore his fierce and cleansing influence, warring against the Moon, had stretched out to kill those three rats under my nose, and under the nose of their natural mistress, the Moon. I had known Mars lean half across Heaven to deal our Lady the Moon some shrewd blow from under his shield, but I had never before seen his strength displayed so effectual.’

‘I don’t understand a bit. Do you mean Mars killed the rats because he hated the Moon?’ said Una.

That is as plain as the pikestaff with which Blagge’s men pushed me forth,’ Mr. Culpeper answered. ‘I’ll prove it. Why had the plague not broken out at the blacksmith’s shop in Munday’s Lane? Because, as I’ve shown you, forges and smithies belong naturally to Mars, and, for his honour’s sake, Mars ’ud keep ’em clean from the creatures of the Moon. But was it like, think you, that he’d come down and rat-catch in general for lazy, ungrateful mankind? That were working a willing horse to death. So then you can see that the meaning of the blazing star above him when he set was simply this: “Destroy and burn the creatures of the Moon, for they are at the root of your trouble. And thus, having shown you a taste of my power, good people, adieu."’

‘Did Mars really say all that?’ Una whispered.

‘Yes, and twice so much as that to any one who had ears to hear. Briefly, he enlightened me that the plague was spread by the creatures of the Moon. The Moon, our Lady of Ill-aspect, was the offender. My own poor wits showed me that I, Nick Culpeper, had the people in my charge, God’s good providence aiding me, and no time to lose neither.

‘I posted up the hill, and broke into Hitheram’s field amongst ’em all at prayers.

‘“Eureka, good people!” I cried, and cast down a dead mill-rat which I’d found. “Here’s your true enemy, revealed at last by the stars.”

‘“Nay, but I’m praying,” says Jack. His face was as white as washed silver.
