Horace's health had long been the reverse of strong. Whether from early delicacy, or from exposure to hardships in Asia, his constitution was never able to respond to the demands made upon it by the society of the capital. The weariness he expresses was often the result of physical prostration. The sketch he has left of himself [39] suggests a physique neither interesting nor vigorous. He was at 44 short, fat, and good- natured looking (rallied, we learn, by Augustus on his obesity), blear- eyed, somewhat dyspeptic, and prematurely grey; and ten years, we may be sure, had not improved the portrait. In the autumn of 8 B.C. Maecenas, who had long been himself a sufferer, succumbed to the effects of his devoted and arduous service. His last message confided Horace to the Emperor's care: "_Horatii flacci ut mei esto memor_." But the legacy was not long a burden. The prophetic anticipations of affection that in death the poet would not be parted from his friend [40] were only too faithfully realised. Within a month of Maecenas's death Horace was borne to his rest, and his ashes were laid beside those of his patron on the Esquiline (November 29, 8 B.C.). As regards the date of publication of his several books, several theories have been propounded, for which the student is referred to the many excellent editions of Horace that discuss the question. We shall content ourselves with assigning those dates which seem to us the most probable. All agree in considering the first book of the Satires to have been his earliest effort. This may have been published in 34 B.C.; and in 29 B.C. the two books of Satires together, and perhaps the _Epodes_. In 24 B.C. probably appeared the first two books of Odes, which open and close with a dedication to Maecenas, and in 23 B.C. the three books of Odes complete; though some suppose that all appeared at once and for the first time in this later year. In 21 B.C. perhaps, but more probably in 20, the first book of the Epistles was published; in 14 B.C. the fourth book of the Odes, though it is possible that the last ode of that book was written at a later date. The second book of Epistles, in which may have been included the _Ars Poetica_, could not have appeared before 10 B.C. It is clear that the latter poem is not complete, but whether Horace intended to finish it more thoroughly it is impossible to say.
