Another popular superstition--in all probability derived from the Egyptians--refers to the setting and rising of Sirius, or the dog-star, as infusing madness into the canine race. Hence the name of the "dog-days" was given by the Romans to the period between the 3d of July and the 11th of August, to which Shakespeare alludes in "Henry VIII." (v. 3): "the dog-days now reign." We may, too, compare the words of Benvolio, in "Romeo and Juliet" (iii. 1):
"For now, these hot days, is the mad blood stirring."
It is obvious, however, that this superstition is utterly groundless, for not only does the star vary in its rising, but is later and later every year. The term "dog-day" is still a common phrase, and it is difficult to say whether it is from superstitious adherence to old custom, or from a belief in the injurious effect of heat upon dogs, that the magistrates, often unwisely, at this season of the year order them to be muzzled or tied up. It was the practice to put them to death; and Ben Jonson, in his "Bartholomew Fair," speaks of "the dog-killer" in this month of August. Lord Bacon, too, in his "Sylva Sylvarum," tells us that "it is a common experience that dogs know the dog-killer, when, as in times of infection, some petty fellow is sent out to kill them. Although they have never seen him before, yet they will all come forth and bark and fly at him."
A "curtal dog," to which allusion is made in "Merry Wives of Windsor" (ii. 1), by Pistol--
denoted "originally the dog of an unqualified person, which, by the forest laws, must have its tail cut short, partly as a mark, and partly from a notion that the tail of a dog is necessary to him in running." In later usage, _curtail dog_ means either a common dog, not meant for sport, or a dog that missed the game, which latter sense it has in the passage above.[416]

_Dragon._ As the type and embodiment of the spirit of evil, the dragon has been made the subject of an extensive legendary lore. The well-known myth of St. George and the Dragon, which may be regarded as a grand allegory representing the hideous and powerful monster against whom the Christian soldier is called to fight, has exercised a remarkable influence for good in times past, over half-instructed people. It has been truly remarked that "the dullest mind and hardest heart could not fail to learn from it something of the hatefulness of evil, the beauty of self-sacrifice, and the all-conquering might of truth." This graceful conception is alluded to by Shakespeare, in his "King John" (ii. 1), where, according to a long-established custom, it is made a subject for sign-painting:[417]
