Othello asks (v. 2):
“Are there no stones in heaven
But what serve for the thunder?”
And in “Julius Cæsar” (i. 3), Cassius says:
“And, thus unbraced, Casca, as you see,
Have bared my bosom to the thunder-stone.”
The thunder-stone is the imaginary product of the thunder, which the ancients called Brontia, mentioned by Pliny (“Nat. Hist.” xxxvii. 10) as a species of gem, and as that which, falling with the lightning, does the mischief. It is the fossil commonly called the Belemnite, or finger-stone, and now known to be a shell.
A superstitious notion prevailed among the ancients that those who were stricken with lightning were honored by Jupiter, and therefore to be accounted holy. It is probably to this idea that Shakespeare alludes in “Antony and Cleopatra” (ii. 5):
“Some innocents ’scape not the thunderbolt.”[146]
The bodies of such were supposed not to putrefy; and, after having been exhibited for a certain time to the people, were not buried in the usual manner, but interred on the spot where the lightning fell, and a monument erected over them. Some, however, held a contrary opinion. Thus Persius (sat. ii. l. 27) says:
“Triste jaces lucis evitandumque bidental.”
The ground, too, that had been smitten by a thunder-bolt was accounted sacred, and afterwards enclosed; nor did any one even presume to walk on it. Such spots were, therefore, consecrated to the gods, and could not in future become the property of any one.
