The publication of Pope's Homer marks an important stage in the development of authorship. Until the time of Dryden no writer had expected to earn his whole living by publishing works of real literature. The medieval minstrels and romancers of the higher class and the dramatists of the sixteenth and seventeenth centuries had indeed supported themselves largely or wholly by their works, but not by printing them. When, in Dryden's time, with the great enlargement of the reading public, conditions were about to change, the publisher took the upper hand; authors might sometimes receive gifts from the noblemen to whom they inscribed dedications, but for their main returns they must generally sell their works outright to the publisher and accept his price. Pope's 'Iliad' and 'Odyssey' afforded the first notably successful instance of another method, that of publication by subscription--individual purchasers at a generous price being secured beforehand by solicitation and in acknowledgment having their names printed in a conspicuous list in the front of the book. From the two Homeric poems together, thanks to this device, Pope realized a profit of nearly £9000, and thus proved that an author might be independent of the publisher. On the success of 'The Iliad' alone Pope had retired to an estate at a London suburb, Twickenham (then pronounced 'Twitnam'), where he spent the remainder of his life. Here he laid out five acres with skill, though in the formal landscape-garden taste of his time. In particular, he excavated under the road a 'grotto,' which he adorned with mirrors and glittering stones and which was considered by his friends, or at least by himself, as a marvel of artistic beauty.
