Ancient Bronze Doors from the Curia Iulia (Senate House in the Forum )
Portone in bronzo dalla Curia ostilia alla Basilica Lateranense
(...) Alessandro VII incaricò il Borromini di portare a termine i lavori per i cinque portali di accesso all’Arcibasilica, di sostituire i battenti della porta centrale -restaurati da Leone X - con quelli in bronzo della Curia ostilia, aula del Senato Romano trasformata da Onorio I (625-638) nella chiesa di sant'Adriano in Tribus Fatis o in tribus Foris o in via Sacra. L'ampiezza del portale lateranense costrinse il Borromini a modificare i battenti provenuti dalla Curia ostilia dai metri 3,268 di larghezza e di 6,798 di altezza agli attuali metri 4,460 per 8,920. Le stelle ad otto punte, elemento araldico chigiano, applicate sui bordi insieme alle ghiande assicurano la verità dell'intervento di Alessandro VII.

From the Curia to the Cathedral
The great bronze doors of St John Lateran (San Giovanni in Laterano), the cathedral of Rome, once belonged to the ancient Curia Julia (Senate House), which still stands in the Forum.
The doors, which date back to the reign of the emperor Domitian (r. 81-96), were moved to the cathedral in 1660, at the bequest of Pope Alexander VII (r. 1655-67), who had them adorned with the heraldic eight-pointed stars of his own coat of arms.

The coat of arms of Pope Alexander VII Chigi (eight-pointed stars ) with the coat of arms Della Rovere
Stelle ad otto punte (dei Chigi) e ghiande (dallo stella araldico Della Rovere) infatti lo stemma uficciale di papa Alessandro VII Chigi era inquartato con la quercia dei Della Rovere**
Alexander VII was born Fabio Chigi, a member of a princely Roman family of Sienese extraction. The heraldic arms of the Chigi family, which takes the form of six mountains surmounted by an eight-pointed star, can be seen all over Rome.
** The Chigi coat of arms is sometimes quartered with that of the Della Rovere family, a privilege conferred on Agostino Chigi (1465-1520), an immensely wealthy banker and patron of the arts, by Pope Julius II (Giuliano della Rovere, r. 1503-13). Rovere is the Italian word for oak and, unsurprisingly, the family's coat of arms incorporates an oak tree. https://www.walksinrome.com/
** Lo stemma papale si blasona: “Inquartato: nel primo e nel quarto della Rovere: d’azzurro alla pianta di rovere sradicata d’oro, i rami passanti in doppia croce di S. Andrea; nel secondo e nel terzo di Chigi: di rosso al monte di sei cime sormontato da una stella a otto punte, il tutto d’oro”.
Lo stemma unisce, inquartandole, le armi di famiglia dei Chigi di Siena con lo stemma dei della Rovere. Lo stemma dei della Rovere si è unito a quello dei Chigi per concessione di Giulio II ad Agostino Chigi, banchiere della Curia Pontificia, che, agli inizi del ‘500, donò al papa la villa “La Suvera” a Pievescola, in provincia di Siena. Per gratitudine il papa gli concesse di inquartare lo stemma con le sue armi.

*Curia Julia: The Roman Senate House
"And certainly, the senate house in particular should be built above all so as to enhance the dignity of the town or city. And if this senate house is going to be square, then whatever its length, its height should be half again as much. If, on the other hand, it is to be oblong, then the length and width should be added together, and half this measure should be given over to the height of the senate house up to the level of the ceiling coffers."
Vitruvius, De Architectura (V.2.1)
*Begun by Julius Caesar to replace the old Curia Hostilia, which had burned (along with the body of Clodius Pulcher) in riots in 52 BC, the new Senate House was completed in 29 BC by Octavian who, two years later, would be given the title of Augustus (Augustus, Res Gestae, XIX; Dio, Roman History, LI.22.1). The Curia Julia may have been afflicted by the Neronian fire of AD 64, the fire of AD 69 on the Capitoline Hill, or a fire in AD 80 during the reign of Titus. Whatever damage was sustained, it was restored by Domitian in AD 94 and, after another disastrous fire in AD 283, completely rebuilt to the same dimensions by Diocletian.
The building was converted to a church in AD 630, which accounts for the preservation of its original porphyry and serpentine floor, the low broad steps that accommodated the senators' seats, and the three large windows. The great bronze doors were removed in the mid-seventeenth century to serve as the portals of the basilica of San Giovanni in Laterano (St. John Lateran)
