For the true laurel-wreath which Glory weaves
Is of the tree no bolt of thunder cleaves.
Stanza xli. lines 4 and 5.
The eagle, the sea calf, the laurel, and the white vine,[591] were amongst the most approved preservatives against lightning: Jupiter chose the first, Augustus Cæsar the second, and Tiberius never failed to wear a wreath of the third when the sky threatened a thunder-storm.[592] These superstitions may be received without a sneer in a country where the magical properties of the hazel twig have not lost all their credit; and perhaps the reader may not be much surprised that a commentator on Suetonius has taken upon himself gravely to disprove the imputed virtues of the crown of Tiberius, by mentioning that a few years before he wrote a laurel was actually struck by lightning at Rome.[593]
