Today, these little stars are used to hide censored words in various texts. The first versions of the symbol were found in cave paintings. Later, the Greek philologist, Aristarchus of Samothrace would use this symbol when correcting Homer’s poetry: that’s how he marked repeated lines. The philosopher, Origen would use this sign to mark missing lines. In the Middle Ages, people started to use the asterisk in a more familiar way, as it meant that there were comments on the text.
