We identify the putatively earliest extant print source of the neoclassical term psychologia, long presumed to have been a 1575 work, as two 1525 works, one by Pier Nicola Castellani and another by Gerhard Synellius. We provide a history of pertinent etymology and introduce the new sources. The full paragraph containing two uses of the term by Castellani is included in translation.
