period. It is not by any means an account of all that he is reading,
but only an arrangement, under certain heads, or places of memoranda
for future use. These notes are extracted from about eighty different
authors, Greek, Latin, French, Italian, and English. Of Greek authors
no less than sixteen are quoted. The notes are mostly notes of
historical facts, seldom of thoughts, never of mere verbal expression.
There is no trace in it of any intention to store up either the
imagery or the language of poetry. It may be that such notes were
made and entered in another volume; for the book thus accidentally
preserved to us seems to refer to other similar volumes of
collections. But it is more likely that no such poetical memoranda
were ever made, and that Milton trusted entirely to memory for the
wealth of classical allusion with which his verse is surcharged. He
did not extract from the poets and the great writers whom he was
daily turning over, but only from the inferior authors and secondary
historians, which he read only once. Most of the material collected
in the commonplace book is used in his prose pamphlets. But when so
employed the facts are worked into the texture of his argument, rather
than cited as extraneous witnesses.

In reading history it was his aim to get at a conspectus of the
general current of affairs rather than to study minutely a special
period. He tells Diodati in September, 1637, that he has studied
Greek history continuously, from the beginning to the fall of
Constantinople. When he tells the same friend that he has been long
involved in the obscurity of the early middle ages of Italian History
down to the time of the Emperor Rudolph, we learn from the commonplace
book that he had only been reading the one volume of Sigonius's
_Historia Regni Italici_. From the thirteenth century downwards he
proposes to himself to study each Italian state in some separate
