Abstract

The dramatic burst of interest in early-type galaxies which took place in the late seventies was triggered both by kinematical observations (Betola and Capaccioli 1975, Illingworth 1977) and by good quality imaging revealing a degree of complexity so far unexpected in these objects. In particular, the discover of isophotal twisting gave support to the triaxial models developed by Binney (1978). Measures of twisting in large samples have been published by a number of authors (e.g. King 1978, Carter 1978, Strom and Strom 1978, Leach 1981, Kent 1984, Lauer 1985, Michard 1985, Djorgovsky 1986, and Jedrzejewski 1987) who obtained percentages of significantly twisted objects up to 60%.
