Interested in what types of studies you will find in this Festschrift? Well, let me just give you a sample. There's thirty-four total, but here's just a highlight from each of the five sections of the book.
From the section covering the Old and New Testament Apocrypha, you'll find a study on the Apocalypse of Abraham, one on the Testament of Job, and one on the apocryphal Acts of Paul and Thecla.
From the section on New Testament philology, you'll find contributions by Paul Danove, Stephen Levinsohn, Jesús Peláez, Luis Gil, Keith Elliott, David Alan Black, Fernando Bermejo, among others. There are studies on translation, syntactical issues, lexical studies, and even a very interesting textual-historical study pertaining to the manuscripts undergirding the Complutensian Greek New Testament. This section (the largest in the book) spans some four hundred pages. It's packed with research.
From the section on the origins of Christianity, you'll find studies like Stan Porter's on assigning dates to the composition of the New Testament texts and the importance doing so has on reconstructing the historical milieu of Christianity at its conception.
From the section on the patristics, you'll find three studies, such as Gonzalo del Cerro's on Pseudo-Clement. And a final section contains some miscellaneous studies, one of which is Chrys Caragounis' discussion on the term "Greco-Roman."
This is truly one of the most impressive Festschrifts I've ever seen. It's really no surprise why so many people agreed to offer a contribution. Antonio Piñero's impact on Greek philology over the past decades certainly deserves the applause offered by his friends and colleagues in this book. Definitely get your hands on a copy of it when you can.
