Opuscula varii argumenti
Various short works on reason
E80 is one of an unusual group of Eneström numbers. It refers to a collection of articles which were published together (in this case E86, E87, E88, E89, E90, and E91), but were written on different topics. Usually referred to as Opuscula Varii Argumenti, Volume 1, this work is part of a three-volume series, the other two parts being E121 (Volume 2) and E156 (Volume 3).
