late 19th century was likely influenced by traditional Irish hurling (rather than Irish football) and points out that this sharing of codes across sports is a natural byproduct of globalisation. Bill Mandle notes that although it lacks evidence that Gaelic Football's come into being in 1880s is a possible indication of Irish Australian influence back home. Arguments were as follows: The two codes were virtually identical in 1885 Aaron Dunne, an Irish sports writer and historian, raises the similarity between the 1885 GAA rules and the 1866 Victorian ones arguing that it is obvious that the GAA used the Victorian rules as a template for Gaelic Football. The similarities included the length and width of the field, the number of players per team (20 vs 21) the distance between the posts, goals and behinds used in the scoring system, the requirement not to throw the ball and the requirement to bounce the ball, everything apart from the shape of the field. Adding weight to this theory is former Gaelic footballer Joe Lennon's thorough post-doctoral research analysing of accounts of caid and GAA codified rules against the Melbourne Football Club rules of 1959 and Victorian Rules of 1866 and 1877 appear to indicate direct copying, some virtually verbatim by the GAA from Australian rules and other football codes, but primarily from the 1866 and 1877 Victorian rules. For example early codified Gaelic called for Australian rules style behind posts (not present in caid and later removed) with 5 point goals scoring (later changed to 3) and 1 point "behind"s all borrowed from Australian Rules, and Rule 27 in reference to kicking styles, Rule 15 relating to foul play and rules dictating playing equipment appear to be directly borrowed from the Victorian Rules. Early Victorian Rules was played with also a round ball until the introduction of the Sherrin in the 1880s. Other than the directly copied rules, analysts argue that so many of the rules are so similar to the Victorian Rules that it would have been impossible for the GAA rule makers not to have obtained a deep knowledge of the Laws of Australian Football. Australian founders had little to no knowledge of Gaelic football Jack Worral in 1926 wrote that the "Father of Australian Football" H. C. A. Harrison who had sought to "code of our own" in 1859 was genuinely surprised in 1927 to learn that the Irish
