do so. By the same principle, a person who wants to mine under somebody's land would have to get permission from the owner to do so, even if the mine entrance was on neighboring land. Origins The phrase is credited to the glossator Accursius in the 13th Century. It has been suggested that the principle was brought to England by Accursius's son, Franciscus Accursius, who came to England with Edward I on the latter's return from the crusades. The principle was firmly established in common law by Edward Coke in Bury v. Pope (1587), which gives the first statement in English law of the principle, writing (Liber 1, section 1, page 4, section "Terra" (earth)): The reporter's note to this case ascribes the maxim to the time of Edward I, which accords with the attribution to Accursius (father and son). Two other cases around 1600 also use the principle, and a number of 19th century cases also apply it. The phrase appears in Blackstone's Commentaries, Book 2, Chapter 2, p. *18: This formulation, though it omits the et ad inferos "and to hell" wording, includes that interpretation ("and the center of the earth"). Largely through the influence of Blackstone, this broader formulation became influential in American law. See Sweeney reference for various formulations of the principle in Anglo-American law. The principle does not occur in classical Roman law. The phrase was used by Accursius in discussion of rights to have burial plots or tombs free from the interference of an overhanging building. In Coke's formulation, he cites three cases involving birds; the circa 1600 cases involve overhanging roofs, while the 19th century cases address diverse topics. The principle attracted increased interest with the development of air and space travel occasioning much discussion, particularly in the 1930s, and the development of space travel yielding further review of the ad coelum doctrine in the 1960s. In American law, the formulation Ab orco usque ad coelum "from Hades all the way to Heaven" by Louis Brandeis is also found. Modern history The steadfast ad coelum doctrine of property began to fall into disfavor with the advent of air and space travel: After the first hot-air balloon flight in 1783, people began to realize that ad coelum could lead to absurd results. Jurists occasionally invoked aerial-balloon trespass as an example of a trivial injury for which the law wouldn't provide redress, and it appears
