- Middle English, from Late Latin obelus, from Greek obelos, a spit, obelus. (American Heritage® Dictionary of the English Language, Fourth Edition)
Examples
“Andrians and Corinthians, and the decree for the mutilation of the captives, of which Philokles was the author.] [Footnote 149: Golden crowns, at this period of Greek history, was the name applied to large sums of money voted by cities to men whose favour they hoped to gain.] [Footnote 150: A spit is called obelus in Greek.] [Footnote 151: Probably of each of the Spartan admirals who had commanded during the war.”
“In the Latin text, the start and end of passages which are deeply corrupt and therefore difficult to correct are indicated by an asterisk, instead of the usual dagger (obelus).”
“_ -- What is the origin of the asterisk, obelus, &c., used for references to notes?”
“Hexapla, the obelus was prefixed to words or lines which were wanting in the Hebrew, and therefore, from Origen's point of view, of doubtful authority, while the asterisk called attention to words or lines wanting in the Septuagint, but present in the Hebrew.”
The Catholic Encyclopedia, Volume 7: Gregory XII-Infallability
“The simple obelus apparently denotes interest, the pointed obelus great interest, the doubly pointed obelus intense interest, and the pointing finger of a carefully drawn hand burning interest.”
“The purpose of the doubly pointed obelus is plainly indicated here, as it accompanies two of these catchwords.”
“It is remarkable, for instance, that on a passage (65, 11) which, as the appended obelus shows, he must have read with attention, he has not added the very different reading of the Parisinus.”
“But such was not the usage of Budaeus; he employed the obelus merely to call attention to something that interested him.”
“In accurate copies these words are marked with an obelus, [1532] which is the sign of rejection.”
“Strabo xi. 507, et sq. [1532] The obelus (/-) is used by Jerome to mark superfluous matter in the lxx.cf. Jer.p. 494, in Canon Fremantle's Translation.”

reesetee A symbol consisting of a line with dots above and below (÷) used to represent the mathematical division operation. Originally, this sign (or a plain line) was used in ancient manuscripts to mark passages that were suspected of being corrupted or spurious. The word comes from the Greek word for a sharpened stick, spit, or pointed pillar--the same root as that of "obelisk." Obelus is sometimes used to refer to another symbol usually known as a dagger.
