So long a period naturally falls into sub-divisions; during its middle part in particular, progress and triumphant romanticism, not yet largely attacked by scientific scepticism, had created a prevailing atmosphere of somewhat passive sentiment and optimism both in society and in literature which has given to the adjective 'mid-Victorian' a very definite denotation. The adjective and its period are commonly spoken of with contempt in our own day by those persons who pride themselves on their complete sophistication and superiority to all intellectual and emotional weakness. But during the 'mid-Victorian' years, there was also a comparative healthiness in the lives of the well-to-do classes and in literature which had never before been equalled and which may finally prove no less praiseworthy than the rather self-conscious freedom and unrestraint of the early twentieth century. The most important literature of the whole period falls under the three heads of essays, poetry, and prose fiction, which we may best consider in that order. LORD MACAULAY. The first great figure, chronologically, in the period, and one of the most clearly-defined and striking personalities in English literature, is Thomas Babington Macaulay, [Footnote: The details of Macaulay's life are known from the; famous biography of him by his nephew, Sir George Trevelyan.] who represents in the fullest degree the Victorian vigor and delight in material progress, but is quite untouched by the Victorian spiritual striving.

From his very babyhood the son displayed almost incredible intellectual precocity and power of memory. His voracious reading began at the age of three, when he 'for the most part lay on the rug before the fire, with his book on the floor, and a piece of bread-and-butter in his hand.' Once, in his fifth year, when a servant had spilled an urn of hot coffee over his legs, he replied to the distressed inquiries of the lady of the house, 'Thank you, madam, the agony is abated.' From the first it seems to have been almost impossible for him to forget anything which had ever found lodgment in, or even passed through, his mind. His childish production of both verse and prose was immense. These qualities and accomplishments, however, did not make him a prig. Both as child and as man, though he was aggressive and showed the prejudices of his class, he was essentially natural and unaffected; and as man he was one of the most cordial and affectionate of companions, lavish of his time with his friends, and one of the most interesting of conversationalists.
