In Hannah Adams
In Adams’s own words, from the 1817 Dictionary. Each passage is quoted verbatim under its own entry.
The Pagans may be divided into the following classes. The more ancient nations, as the Chaldeans, Phenicians, Sabians, and the like.
Hannah Adams, A Dictionary of All Religions (Boston, 1817), entry “Pagans” (the Chaldeans are subsumed there).
