their concurring testimonies, all would be disposed to take this
interruption of their sleep for one of its most fantastic dreams. The
elderly gentleman, who figured in this delirious _pas seul_--who was
he? He was Tiberius Caesar, king of kings, and lord of the terraqueous
globe. Would a British jury demand better evidence than this of a
disturbed intellect in any formal process _de lunatico inquirendo_?
For Caligula, again, the evidence of symptoms is still plainer. He knew
his own defect; and purposed going through a course of hellebore.
Sleeplessness, one of the commonest indications of lunacy, haunted him in
an excess rarely recorded. [Footnote: No fiction of romance presents so
awful a picture of the ideal tyrant as that of Caligula by Suetonius. His
palace--radiant with purple and gold, but murder every where lurking
beneath flowers; his smiles and echoing laughter--masking (yet hardly
meant to mask) his foul treachery of heart; his hideous and tumultuous
dreams--his baffled sleep--and his sleepless nights--compose the picture
of an AEschylus. What a master's sketch lies in these few lines:
"Incitabatur insomnio maxime; neque enim plus tribus horis nocturnis

qui inter ceteras pelagi quondam speciem colloquentem secum videre visus
sit. Ideoque magna parte noctis, vigilse cubandique tsedio, nunc toro
residens, nunc per longissimas porticus vagus, invocare identidem atque
exspectare lucem consueverat:"--i. e., But, above all, he was tormented
with nervous irritation, by sleeplessness; for he enjoyed not more than
three hours of nocturnal repose; nor these even in pure untroubled rest,
but agitated by phantasmata of portentous augury; as, for example, upon
one occasion he fancied that he saw the sea, under some definite
impersonation, conversing with himself. Hence it was, and from this
incapacity of sleeping, and from weariness of lying awake, that he had
fallen into habits of ranging all the night long through the palace,
sometimes throwing himself on a couch, sometimes wandering along the vast
