The Secret Jews in Portugal by Amílcar Paulo is a revealing work that uncovers the hidden history of Portuguese crypto-Jews—those who, forced by the Inquisition, publicly embraced Christianity while secretly maintaining their Jewish roots. Through exhaustive historical research and analysis of diverse sources, Paulo reconstructs the lives of these families and their persistent connection to Judaism, passed down through generations, even under the yoke of religious repression. The author not only explores the oppressive methods of the Inquisition but also documents how crypto-Jews adapted their practices and beliefs to survive. Through secret rituals and hidden symbols, these communities preserved their traditions, creating a camouflaged Jewish identity that lasted until the 19th century, long after the official abolition of the Inquisition in Portugal. One of the book's most valuable contributions is its collection of prayers and hidden traditions that crypto-Jews kept behind closed doors. These practices, passed down in secrecy from one generation to the next, form a crucial part of the cultural legacy of the crypto-Jews and stand as a testament to their resilience in the face of persecution. Paulo presents specific examples of these rituals and prayers, shedding light on a vital aspect of the lives of these hidden Jews. With an accessible approach and rigorous narrative, The Secret Jews in Portugal is an essential read for those interested in the history of the crypto-Jews. Amílcar Paulo offers a deep reflection on cultural and religious resistance, as well as an invitation to explore the forgotten legacy of these hidden Jews, whose stories continue to shape Portugal's cultural identity today.
