The Pompeii Project of the University of Helsinki (Expeditio Pompeiana Universitatis Helsingiensis, EPUH), first directed by Paavo Castrén (2002-2009) and then by Antero Tammisto (2009-), has as its goal the documentation, analysis, and publishing of all the structural and material remains, wall paintings, and finds of a single Pompeian city block, Insula IX 3. This volume is dedicated to the exceptionally rich finds of its largest unit, the House of Marcus Lucretius (IX3,5.24).
