The first recorded uses of steganography can be traced back to 440 BC in [[Greece]], when [[Herodotus]] mentions two examples in his ''[[The Histories of Herodotus|Histories]]''.<ref>{{cite journal |url=http://www.cl.cam.ac.uk/~fapp2/publications/ieee99-infohiding.pdf |title=Information Hiding: A survey |journal=Proceedings of the IEEE |last= Petitcolas |first=FAP |author2=Anderson RJ |author3=Kuhn MG  |volume=87 |issue=7 |pages=1062–78 |access-date=2 September 2008 |doi=10.1109/5.771065 |year=1999|citeseerx=10.1.1.333.9397 }}</ref> [[Histiaeus]] sent a message to his vassal, [[Aristagoras]], by shaving the head of his most trusted servant, "marking" the message onto his scalp, then sending him on his way once his hair had regrown, with the instruction, "When thou art come to Miletus, bid Aristagoras shave thy head, and look thereon." Additionally, [[Demaratus]] sent a warning about a forthcoming attack to Greece by writing it directly on the wooden backing of a [[wax tablet]] before applying its beeswax surface. Wax tablets were in common use then as reusable writing surfaces, sometimes used for [[shorthand]].

In his work ''[[Polygraphia (book)|Polygraphiae]],'' [[Johannes Trithemius]] developed his [[Ave Maria cipher|''Ave Maria'' cipher]] that can hide information in a Latin praise of God.<ref>{{cite web |url=http://daten.digitale-sammlungen.de/~db/0002/bsb00026190/images/index.html?seite=71|title=Polygraphiae (cf. p. 71f) |publisher = Digitale Sammlungen |language = de |access-date=27 May 2015}}</ref>{{better source|reason=This citation is for the book itself rather than to a reliable source that explains it.|date=March 2025}} "{{lang|la|Auctor sapientissimus conseruans angelica deferat nobis charitas potentissimi creatoris}}", for example, contains the concealed word ''VICIPEDIA''.{{cn|date=March 2025}}
