sciat alter_). I might be of Thucydides' opinion, [59]"to know a thing and
not to express it, is all one as if he knew it not." When I first took this
task in hand, _et quod ait [60]ille, impellents genio negotium suscepi_,
this I aimed at; [61]_vel ut lenirem animum scribendo_, to ease my mind by
writing; for I had _gravidum cor, foetum caput_, a kind of imposthume in my
head, which I was very desirous to be unladen of, and could imagine no
fitter evacuation than this. Besides, I might not well refrain, for _ubi
dolor, ibi digitus_, one must needs scratch where it itches. I was not a
little offended with this malady, shall I say my mistress Melancholy, my
Aegeria, or my _malus genius_? and for that cause, as he that is stung with
a scorpion, I would expel _clavum clavo_, [62]comfort one sorrow with
another, idleness with idleness, _ut ex vipera Theriacum_, make an antidote
out of that which was the prime cause of my disease. Or as he did, of whom
[63]Felix Plater speaks, that thought he had some of Aristophanes' frogs in
his belly, still crying _Breec, okex, coax, coax, oop, oop_, and for that
cause studied physic seven years, and travelled over most part of Europe to
ease himself. To do myself good I turned over such physicians as our
libraries would afford, or my [64]private friends impart, and have taken
this pains. And why not? Cardan professeth he wrote his book, _De
Consolatione_ after his son's death, to comfort himself; so did Tully write
of the same subject with like intent after his daughter's departure, if it
be his at least, or some impostor's put out in his name, which Lipsius
probably suspects. Concerning myself, I can peradventure affirm with Marius
in Sallust, [65]"that which others hear or read of, I felt and practised
myself; they get their knowledge by books, I mine by melancholising."
_Experto crede Roberto_. Something I can speak out of experience,
_aerumnabilis experientia me docuit_; and with her in the poet, [66]_Haud
ignara mali miseris succurrere disco_; I would help others out of a
fellow-feeling; and, as that virtuous lady did of old, [67]"being a leper
herself, bestow all her portion to build an hospital for lepers," I will
