"The Revealing Charm will reveal invisible ink and messages hidden by magical means. Simply tap a book or parchment with your wand and any hidden message will be revealed. This spell is more than sufficient to overcome the basic concealing charms and so is a favourite of parents and teachers alike."
Miranda Goshawk, Book of Spells[src]

The Revealing Charm[3] (Aparecium)[1] was a charm that revealed secret messages written in invisible ink, or any other hidden markings written using other means such as Concealing charms.[4]


"She tapped the diary three times and said, "Aparecium!" Nothing happened."
— Hermione using the spell on Tom Riddle's diary[src]

On 1 February, 1993, Hermione Granger used this spell on Tom Riddle's Diary to see if anything could be read. Nothing appeared after she used the spell because that was not the enchantment placed on the book.[1] This spell is also listed in the Book of Spells' (chapter 2) by Miranda Goshawk.[4]

The Revealing Charm may have been the implied spell Snape used when he tapped the Marauder's Map with his wand and ordered the parchment to "reveal your secrets" before being insulted by the Marauders.[5]

During the 2008–2009 school year, a student used this spell to reveal the chains that was trapping Gossamer in his portrait.[6]
