Fleta is the name of an early treatise on the common law of England. It was written in Latin with the sub-title seu Commentarius juris Anglicani.[1] The anonymous author of the book is sometimes referred to as "Fleta", although this is not in fact a person's name.[2] The book acquired its common title because its preface contains a remark that it could be called "Fleta" because it was written in "Fleta"; however, the meaning of this comment is unclear (see the section on authorship below).
From internal evidence, the work appears to have been written in the reign of Edward I, and it seems to have been completed shortly after the year 1290.[3]
