“In such a night
Medea gather’d the enchanted herbs,
That did renew old Æson.”

And in “Hamlet” (iv. 7) the description which Laertes gives of the weapon-poison refers to the same notion:

“I bought an unction of a mountebank,
So mortal that, but dip a knife in it,
Where it draws blood no cataplasm so rare,
Collected from all simples that have virtue
Under the moon, can save the thing from death.”

The sympathy of growing and declining nature with the waxing and waning moon is a superstition widely spread, and is as firmly believed in by many as when Tusser, in his “Five Hundred Points of Good Husbandry,” under “February” gave the following advice:

“Sow peason and beans in the wane of the moon,
Who soweth them sooner, he soweth too soon,
That they with the planet may rest and arise,
And flourish, with bearing most plentifull wise.”

Warburton considers that this notion is alluded to by Shakespeare in “Troilus and Cressida” (iii. 2), where Troilus, speaking of the sincerity of his love, tells Cressida it is,

“As true as steel, as plantage to the moon,
As sun to day, as turtle to her mate.”

There is a little doubt as to the exact meaning of plantage in this passage. Nares observes that it probably means anything that is planted; but Mr. Ellacombe, in his “Plant-lore of Shakespeare” (1878, p. 165), says “it is doubtless the same as plantain.”

It appears that, in days gone by, “neither sowing, planting, nor grafting was ever undertaken without a scrupulous attention to the increase or waning of the moon.”[119] Scot, in his “Discovery of Witchcraft,” notes how “the poore husbandman perceiveth that the increase of the moone maketh plants fruitful, so as in the full moone they are in best strength; decaieing in the wane, and in the conjunction do utterlie wither and vade.”

It was a prevailing notion that the moon had an attending star—Lilly calls it “Lunisequa;” and Sir Richard Hawkins, in his “Observations in a Voyage to the South Seas in 1593,” published in 1622, remarks: “Some I have heard say, and others write, that there is a starre which never separateth itself from the moon, but a small distance.” Staunton considers that there is an allusion to this idea in “Love’s Labour’s Lost” (iv. 3), where the king says:
