Peristylium
Peristylium or PERISTYLUM. The Greek adjective περίστυλος is applied either to a court surrounded by colonnades on the inside, or to a building surrounded by them on the outside, as a temple. It is then used alone, in all three genders, with a substantive understood, for a court with colonnades: hence the Latin peristylum, or more commonly the substantive form peristyliumn. It is especially used for the courts of a Greek dwellinghouse, and for that introduced into Roman houses in imitation of them. [DOMUS Vol. 1. p. 671.]
