In 1481 or 1482, 
Sir Thomas de Littleton wrote a then-famous work called “A Treatise on Tenures.” More than a century later, 
Sir Edward Coke commented on this work, by writing 
“The First Part of the Institutes of the Lawes of England, or a Commentary on Littleton” in 1628. More than a century after that, 
Sir William Blackstone discussed 
Coke’s work in the first volume of his 
“Commentaries on the Laws of England” in 1765. 
Coke is the person that 
Blackstone cited the most in the “Commentaries.” In this great work, 
Blackstone thus wrote a brief summary of 
Sir Edward Coke’s writings, to set up his esteemed source (whom he would use often throughout his work). He prefaced this summary with the following praise:
Sir Edward Coke
Lord Chief Justice Coke was “a man of infinite learning in his profession”
“Some of the most valuable of the ancient reports are those published by 
lord chief justice Coke; a man of infinite learning in his profession, though not a little infected with the pedantry and quaintness of the times he lived in, which appear strongly in all his works. However his writings are so highly esteemed, that they are generally cited without the author's name 
[footnote].” (Source: 
Blackstone’s “Commentaries,” Introduction, Section 3)
Sir Thomas de Littleton
Blackstone's summary of Sir Edward Coke ...
Blackstone then gave his brief summary of 
Sir Edward Coke's writings:
“ … the same learned judge we have just mentioned, 
Sir Edward Coke; who hath written four volumes of institutes, as he is pleased to call them, though they have little of the institutional method to warrant such a title. The first volume is a very extensive comment upon a little excellent treatise of tenures, compiled by 
judge Littleton in the reign of Edward the fourth. This comment is a rich mine of valuable common law learning, collected and heaped together from the ancient reports and year books, but greatly defective in method.” (Source:
