The _Arcadia_ was entered in the Register of the Stationer’s Company in 1588, by William Ponsonbie, the publisher of Spenser’s _Fairie Queene_; and the first edition saw the light in a thick quarto in 1590. A photo-lithographic reproduction of this handsome first edition was published in 1891 by Dr Oskar Sommer, to whose scholarly bibliographical introduction I am indebted for the following list of the various editions. The fourth and fifth books, and a portion of the third book (57 pages), were added in the second edition, in 1593, a folio, by the same publisher. Beyond this, there are few variations in the text of the two editions. The third edition (1598), also by Ponsonbie, comprised Sidney’s _Sonnets_, _Astrophel and Stella_, and the _Defence of Poesie_; and these works were again included in the fourth edition (misdescribed as the third) by Robert Waldegrave, at Edinburgh, in 1599.[i02] Mathew Lownes’ edition (1605), the fifth (miscalled the fourth), is almost a facsimile reprint of the third; but in the next edition, described on the title-page as the fourth (1613), we get some new “additions,” but of small importance compared with those in the seventh (described in the title as the fifth), published in 1621 at Dublin, which included a “Supplement of a defect in the third part {xxiv} of this History, by Sir W. Alexander,” which had been printed separately at Dublin the same year. In the present edition his supplement begins on page 428 and ends on page 451, where Sir William’s apologie for the liberty taken is duly quoted. Sir William Alexander of Menstrie, afterwards Earl of Stirling, was a poet and dramatist, and a statesman of genius, who died in 1610. He was a friend of Drummond of Hawthornden. The _Dictionary of National Biography_ states wrongly that he published this continuation of the third book of the _Arcadia_ in 1613, the date of the so-called fourth edition, certain copies of which have extracts from this work inserted. The first London edition, to which Sir William Alexander’s supplement was added, was the eighth, published in 1623; but it is doubtful whether the additional matter was really printed as a part of the volume, or added from the 1621 edition, or some other of which there is no trace, to the only copy of this issue known to Dr Sommer. The pagination, at any rate, is in a confused state pointing to this.
