jats:pThe law‐text known as I Æthelstan is commonly accepted as the earliest evidence of a legal obligation to pay tithes in England. As it turns out, it might not be. The extant Old English version of I Æthelstan does indeed legislate for tithe payments. However, this version is an eleventh‐century revision of the original text, probably penned by Archbishop Wulfstan of York (d. 1023). As I will argue in this article, the original version, which survives only as contained in a twelfth‐century translation into Latin, appears to be a call for a one‐off charitable alms payment.</jats:p>
