Andrea Maraschi is a historian whose research focuses on medieval Europe, with particular attention to religion, food culture, and social beliefs. His work examines how everyday practices such as diet and food preparation intersected with religious doctrine, superstition, and accusations of heresy. Maraschi is the author of "Food, Heresies, and Magical Boundaries in the Middle Ages," published by Amsterdam University Press in 2024. The book analyzes how medieval societies connected certain foods and culinary practices with moral suspicion, magic, and religious deviance. Drawing on theological texts, legal records, and cultural sources, Maraschi studies how food taboos and beliefs about magic shaped boundaries between orthodox belief and heresy in medieval communities.
