Editing Butterfly loop (section)

==History==

The earliest known presentation of the knot was in A.A. Burger's 1914 work ''Rope and Its Uses'', included in an [[agricultural extension]] bulletin from what is now [[Iowa State University]].<ref name="aksday80">{{citation|first=Cyrus Lawrence|last=Day|title=The Art of Knotting and Splicing|edition=4th|location=Annapolis|publisher=Naval Institute Press|year=1986|pages=80–81}}</ref>   Burger called the knot a '''lineman's rider''' stating it was often used by "[[Lineman (technician)|linemen]] and especially telephone men". The knot's security and ability to withstand tension in any direction are both discussed.<ref name="Burger1914">{{Cite journal|first=A.A.|last=Burger|title=Rope and Its Uses|pages=24–25|year=1914|url=https://books.google.com/books?id=Ju4sAAAAYAAJ&pg=RA1-PA24|publisher=Iowa State College of Agricultural and Mechanic Arts|journal=Extension Bulletin 24|volume=XIII|issue=8|location=Ames|access-date =2010-09-09}}</ref>

The knot's association with [[mountaineering]]—and with [[butterflies]]—originates from a 1928 article in ''[[Alpine Journal]]'' by C.E.I. Wright and J.E. Magowan.<ref name="hsok-ch9">{{Citation| last=Warner| first=Charles| year=1996| contribution=A History of Life Support Knots| editor-last=Turner| editor-first=J.C.| editor2-last=van de Griend| editor2-first=P.| title=History and Science of Knots| series=K&E Series on Knots and Everything| location=Singapore| publisher=World Scientific Publishing| volume=11| pages=157–160| isbn=981-02-2469-9}}</ref>   The authors claim to have developed the '''butterfly noose''' themselves while attempting to improve the selection of knots available to climbers.   The name is "so styled on the basis of a more or less fanciful resemblance imagined in the form of the knot."  In the second part of the article they express dissatisfaction regarding their earlier use of the word "noose," since the knot is non-collapsing, and refer to the knot as '''butterfly loop''' or simply '''butterfly'''.<ref name="WandM_AJ">{{cite journal |last1=Wright |first1=C.E.I. |last2=Magowan |first2=J.E. |year=1928 |title=Knots for Climbers |journal=Alpine Journal |publisher=[[Alpine Club (UK)|Alpine Club]]|location=London |issue=40 |pages=120–140, 340–351 }}</ref>  Wright and Magowan call the butterfly loop "new," along with several other of their knots, in the sense they were unable to identify any earlier record of them. However, they prudently added that it "might be rash to claim they have never been used before."<ref name="WandM_AJ_140">Wright & Magowan, p. 140.</ref>

[[Clifford Warren Ashley|Clifford Ashley]] presented the knot in 1944 (text & image #1053), calling it the '''lineman's loop'''; he attributed its first publication to J.M. Drew, but made no specific reference as to the source of this claim.<ref name="ashley191">{{citation |last=Ashley |first=Clifford W. |title=The Ashley Book of Knots |year= 1944 |publisher=Doubleday |location=New York |page=191 }}</ref>  A 1912 article called "Some Knots and Splices" by Drew appears in the bibliography of ''[[The Ashley Book of Knots]]''.<ref>Ashley, p. 595</ref>   A 1913 reprint of this Drew article does not mention the butterfly loop.<ref>{{cite journal |last1=Drew |first1=J.M. |year=1913 |title=Some Knots and Splices |journal=Irrigation Age |location=Chicago|publisher=D.H.

But in his contributed "Chapter 12 Rope Work", pp.202 .. 252 to Lester Griswold's Handicraft does present the knot. (Curiously, Ashley gives no hint that this book which he twice praises contains a full knots chapter written by Drew!)
