About frontispiece

In architecture, the term frontispiece is used to describe the principal face of the building, usually referring to a combination of elements that frame and decorate the main or front entrance of a building. The earliest and most notable variation of frontispieces can be seen in Ancient Greek Architecture which features a large triangular gable, known as a pediment, usually supported by a collection of columns. However, some architectural authors have often used the term "frontispiece" and "pediment" interchangeably in reference to both large frontispieces decorating the main entrances, as well as smaller frontispieces framing windows which is traditionally known as a pediment.
