This is a momentous occasion. The publication of the final fascicule of the Groningen edition of the scholia to Aristophanes marks the completion of the scholarly endeavours of nearly half a century, made possible by the support of the NWO (The Netherlands Organisation for the Advancement of Pure Research). The project began in 1960, under the supervision of W.J.W. Koster (until 1975) and latterly of D. Holwerda, who has seen it through to completion in the new millennium with the appearance of the scholia to the Thesmophoriazusae and Ecclesiazusae edited by Remco Regtuit.

Given that this slender, handsome volume sets the capstone upon nearly fifty years of international cooperation in the painstaking process of producing the first new critical edition of the complete scholia to Aristophanes since Dübner’s in 1842, the reader will forgive the inclusion of a brief list of the contributors and their achievements.
