Each of these details have been the subject of significant research and debated widely among historians, critics, apologists and polemicists, sparking a variety of historical and theological interpretations. In the fall of 1967 the Reverend Wesley P. Walters published a pamphlet asserting that the "unusual excitement" Joseph Smith wrote of matched the Palmyra revival of 1824, and was anachronistic to the 1820 setting. Walters's pamphlet created a stir, and provoked a strong response from scholars at Brigham Young University (BYU). By spring of 1968 BYU Professor Truman G. Madsen organized around three dozen scholars to respond to Walters, and wrote to the First Presidency of the LDS Church that the "first vision has come under severe historical attack." Walters's thesis and the subsequent response has framed the historical debate.
