The Graces were three Greek goddesses of charm, grace and beauty. Cicero is referring here to the tendency amongst the Roman elite to display their wealth, cultured upbringing, classical education and good taste through art inspired by the Greek myths and culture, or replicas based on original Greek art. This inevitably led to the same fashionable subjects being repeated over and over in all the grand (and those with pretensions of grandeur) Roman houses.
