This manuscript, titled *Sefer Ta'amulot Hokhmah* ("Book of Secrets of Wisdom"), is a collection of medical recipes, cures, amulets, and other writings by Aron Henriques da Cunha, a Jewish doctor or pharmacist practicing in the Netherlands and/or the Caribbean Islands between 1770 and 1820. Written in a mix of Spanish, Dutch, German, and Hebrew, the manuscript also includes seven leaves of genealogical records for Cunha's family in the Caribbean and Naarden, Holland, dating up to 1835. The manuscript is described as a personal notebook where the physician recorded his work over an extended period; while some passages may be copied from other sources, the work is largely original.
