Landor's poetical productions, which are numerous, are spread over the greater part of his life; his prose, by which he is chiefly known, dates in the main from the last forty years of it, the best being written between 1820 and 1840. The greater part of this prose takes the form of "Imaginary Conversations"--sometimes published under separate general headings, sometimes under the common title--between characters of all ages, from the classical times to Landor's. Their bulk is very great; their perfection of style at the best extraordinary, and on the whole remarkably uniform; their value, when considerations of matter are added to that of form, exceedingly unequal. For in them Landor not only allowed the fullest play to the ungovernable temper and the childish crotchets already mentioned, but availed himself of his opportunities (for, though he endeavoured to maintain a pretence of dramatic treatment, his work is nearly as personal as that of Byron) to deliver his sentiments on a vast number of subjects, sometimes without too much knowledge, and constantly with a plentiful lack of judgment. In politics, in satiric treatment, and especially in satiric treatment of politics, he is very nearly valueless. But his intense familiarity with and appreciation of classical subjects gave to almost all his dealings with them a value which, for parallel reasons, is also possessed by those touching Italy. And throughout this enormous collection of work (which in the compactest edition fills five large octavo volumes in small print), whensoever the author forgets his crotchets and his rages, when he touches on the great and human things, his utterance reaches the very highest water-mark of English literature that is not absolutely the work of supreme genius.
