This Tertullian seems to have done in his treatise De Ecstasi, which is mentioned by St. Jerome—see his Catalogus Scriptt. Eccles. (in Tertulliano); and by Nicephorus, Hist. Eccles. iv. 22, 34. On this subject of ecstasy, Tertullian has some observations in De Anima, chap. xxi. and xlv. (Rigalt. and Oehler.)
