The volume "Coincidences and Necessities" gathers twelve theatrical studies, mostly still unpublished, from the last two years of research inquiries, which combine considerations of terminology and the publishing of theatrical texts with the analysis of unknown or rarely published works, featuring topics of bibliography and interpretation of dramatic and dialogic works, spanning from the Middle Ages to the end of the 20th century.

It specifically includes: "For the Theatre, Not for the Drama", "Notes on Greek Terminology Regarding the Art of Dionysus", "Selected Comments on the Cypriot Cycle of Passions", "Publishing Considerations in Greek Theatrical Texts of the Venetian and Ottoman Periods", "A Kefalonian in Constantinople. Linguistic Satire in Unpublished and Recently Published Dramatic Texts of the 18th and 19th Centuries", "Unpublished Translation of Voltaire in the Pre-Revolutionary Greek Theatre: The Scottish Woman by Georgios Kabbakos (1806)", "Speech and Satire in 19th Century Zakynthos: The Kakava by N. B. Karatzas (1834)", "An Unbibliographed Philhellenic Work: Misolonghi by Jos. Bar. Ow, Innsbruck 1860", "Bibliographic Exercises in 19th Century Greek Dramaturgy (1864-1900). The Standalone Editions", "Fausta by Vernardakis, the Swan Song of Greek Romanticism", "Theatrical Translations by Vasilis Rojas. Schiller: Don Carlos, Maria Stuart, Hauptmann: Rosa Bernd, Hanela Goes to Heaven", "Lazarus by Pantelis Prevelakis and the Greek Tradition" and "Orality and Punctuation in the Dramatic Speech of Iakovos Kampanellis".

These studies, wherever published, have been revised for this volume; the latest achievements of the relevant research have been added, and in many cases, the most recent bibliography is included in the footnotes. At the end of the volume, there are detailed indexes that also allow for selective use of the volume.
