[[Isidore of Seville]] (c. 560–636) described the use of the symbol as follows: "The obelus is appended to words or phrases uselessly repeated, or else where the passage involves a false reading, so that, like the arrow, it lays low the superfluous and makes the errors disappear&nbsp;...

Medieval scribes used the symbols extensively for critical markings of manuscripts. In addition to this, the dagger was also used in notations in early [[Christianity]], to indicate a minor intermediate pause in the [[chanting]] of [[Psalms]], equivalent to the [[quaver rest]] notation or the trope symbol in [[Hebrew cantillation]]. It also indicates a breath mark when reciting, along with the asterisk, and is thus frequently seen beside a [[comma]].<ref name="fenlon">{{cite book |editor-first= Iain |editor-last=Fenlon |author1first1=Kay |last1=Kaufman Shelemay |author2first2=Peter |last2=Jeffery |author3first3=Ingrid Monson |name-list-stylelast3=ampMonson |title =Early Music History: Studies in Medieval and Early Modern Music|year |date=1994 |chapter= Oral and written transmission in Ethiopian Christian chantChant |publisher=Cambridge University Press |page=81 |isbn =978-0-521-45180-29780521451802 |chapter-url= =https://books.google.com/books?id=Xt9FzmdCdskC&q=obelus%20dagger&pg=PA81}}</ref><ref name="seiyaku">{{cite web |url= http://www.seiyaku.com/customs/crosses/obelisk.html |title=Obelisk, Obelus, Dagger |publisherwork=seiyakuSeiyaku.com |access-date=August 26, August 2011 |archive-url= https://web.archive.org/web/20110929075757/http://www.seiyaku.com/customs/crosses/obelisk.html |archive-date=29 September 29,2011 2011|url-status=live|df=mdy-all}}</ref>
 
In the 16th century, the printer and scholar [[Robert Estienne]] (also known as Stephanus in [[Latin]] and Stephens in English) used it to mark differences in the words or passages between different printed versions of the Greek [[New Testament]] (''[[Textus Receptus]]'').<ref name="martin">{{cite book |authorfirst=David |last=Martin (French divine)|title =A criticalCritical dissertationDissertation upon the seventhSeventh verseVerse of the fifthFifth chapterChapter of St. John's First Epistle: thereThere are three that bear record in Heaven, &c. : wherein the authentickness of this text is fully prov'd against the objections of Mr. Simon and the modern Arians |publisher =Printed for William and John Innys |chapter=Chap.

Due to the variations as to the different uses of the different forms of the obelus, there is some controversy as to which symbols can actually be considered an obelus. The {{char|⨪}} symbol and its variant, the {{char|÷}}, is sometimes considered to be different from other obeli. The term 'obelus' may have referred strictly only to the horizontal slash and the dagger symbols.{{cn|date=January 2023}}
 
== Modern usage ==
The dagger usually indicates a [[footnote]] if an asterisk has already been used.<ref name="partridge" /> A third footnote employs the double dagger.<ref name="H&F">{{cite web |url= http://www.typography.com/ask/showBlog.php?blogID=190 |authorlast=Hoefler, |first=Jonathan |title=House of Flying Reference Marks, or Quillon & Choil |publisher=Hoefler & Frere-Jones |date=4 June 2009 |author-link=Jonathan Hoefler |access-date=6 April 2010 |archive-url= https://web.archive.org/web/20100205102319/http://typography.com/ask/showBlog.php?blogID=190 |archive-date=5 February 2010 |url-status=dead|df=dmy-all}}</ref> Additional footnotes are somewhat inconsistent and represented by a variety of symbols, e.g., [[vertical bar|parallels]] ( {{larger|‖}} ), [[section sign]] {{char|§}}, and the [[pilcrow]] {{char|¶}}{{snd}} some of which were nonexistent in early modern [[typography]]. Partly because of this, [[superscript]] [[numeral system|numeral]]s have increasingly been used in modern literature in the place of these symbols, especially when several footnotes are required. Some texts use asterisks and daggers alongside superscripts, using the former for per-page footnotes and the latter for [[endnote]]s.
