This commentary is the sequel to G.A.A. Kortekaas' The Story of Apollonius, King of Tyre: A Study of Its Greek Origin and an Edition of the Two Oldest Latin Recensions. Whereas the critical edition (2004) could only briefly touch upon the numerous problems raised by the text concerning the origin (Latin or rather Greek?), the time and place of creation, the genesis of the text, the interrelation between the numerous manuscripts, especially between the two main recensions RA and RB, the present volume does address these issues in a detailed commentary, word by word and line by line. The many links with the Greek Novel, which today stands in the centre of scholarly interest, are striking. In this commentary the author attempts to show that the novel originated in Greece, or more precisely Asia Minor, possibly Tarsus. The two recensions (RA and RB) are closely compared, preference generally being given to RA. The volume discusses in detail the most recent publications on the subject. All these aspects make the present commentary attractive to scholars of many different disciplines.
