, abounding in marble, and {the island} wherein
the treacherous Sithonian[89] betrayed the citadel, on receiving the
gold, which, in her covetousness, she had demanded. She was changed into
a bird, which even now has a passion for gold, the jackdaw {namely},
black-footed, and covered with black feathers.

[Footnote 74: _A gloomy cave._--Ver. 409. This cavern was called
Acherusia. It was situate in the country of the Mariandyni, near
the city of Heraclea, in Pontus, and was said to be the entrance
of the Infernal Regions. Cerberus was said to have been dragged
from Tartarus by Hercules, through this cave, which circumstance
was supposed to account for the quantity of aconite, or wolfsbane,
that grew there.]

[Footnote 75: _Call it aconite._--Ver. 419. From the Greek
+akone+, 'a whetstone.']

[Footnote 76: _Presented to his son._--Ver. 420. Medea was anxious
to secure the succession to the throne of Athens to her son Medus,
and was therefore desirous to remove Theseus out of the way.]

[Footnote 77: _Tokens of his race._--Ver. 423. AEgeus, leaving
AEthra at Troezen, in a state of pregnancy, charged her, if she bore
a son, to rear him, but to tell no one whose son he was. He placed
his own sword and shoes under a large stone, and directed her to
send his son to him when he was able to lift the stone, and to
take them from under it; and he then returned to Athens, where he
married Medea. When Theseus had grown to the proper age, his
mother led him to the stone under which his father had deposited
his sword and shoes, which he raised with ease, and took them out.
It was, probably, by means of this sword that AEgeus recognized his
son in the manner mentioned in the text.]

[Footnote 78: _Marathon._--Ver. 434. This was a town of Attica,
adjoining a plain of the same name, where the Athenians, under the
command of Miltiades, overthrew the Persians with immense
slaughter. The bull which Theseus slew there was presented by
Neptune to Minos. Being brought into Attica by Hercules, it laid
waste that territory until it was slain by Theseus.]

[Footnote 79: _Cromyon._--Ver. 435. This was a village of the
Corinthian territory, which was infested by a wild boar of
enormous size, that slew both men and animals. It was put to death
by Theseus.]
