CANCEL (from the Lat. cancelli, a plural diminutive of cancer, a grating or lattice, from which are also derived “chancel” and “chancellor”), a word meaning to cross out, from the crossed latticed lines drawn across a legal document to annul it, hence to delete or destroy.
CANCELLI (plural of Lat. cancellus, dim. of cancer, a crossing bar), in architecture, the term given to barriers which correspond to the modern balustrade or railing, especially the screen dividing the body of a church from the part occupied by the ministers; hence “chancel” (q.v.). By the Romans cancelli were similarly employed to divide off portions of the courts of law (cf. the English “bar”).
CANCER, LUIS (d. 1549), Spanish missionary to Central America, was born at Barbastro near Saragossa. After working for some time in Dominica and Haiti, he crossed to the mainland, where he had great success in pacifying the Indians whom more violent methods had failed to subdue. He upheld the cause of the natives at an ecclesiastical assembly held in Mexico in 1546, and three years later, on the 26th of June, met his death at their hands on the west coast of Florida.
CANCER (“The Crab”), in astronomy, the fourth sign of the zodiac, denoted by the symbol
. Its name may be possibly derived from the fact that when the sun arrives at this part of the ecliptic it apparently retraces its path, resembling in some manner the sidelong motion of a crab. It is also a constellation, mentioned by Eudoxus (4th century b.c.) and Aratus (3rd century b.c.); Ptolemy catalogued 13 stars in it, Tycho Brahe 15 and Hevelius 29. Its most interesting objects are: a large loose cluster of stars, known as Praesepe or the Beehive, visible as a nebulous patch to the naked eye, and ζ Cancri, a remarkable multiple star, composed of two stars, of magnitudes 5 and 5.7, revolving about each other in 60 years, and a third star of magnitude 5.5 which revolves about these two in an opposite direction in a period of 17½ years; from irregularities in the motion of this star, it is supposed to be a satellite of an invisible body which itself revolves about the two stars previously mentioned, in a period of 600 to 700 years.
