Giuseppe Vasi dedicated his 1753 book of etchings showing the seven basilicas and other ancient churches of Rome to Pope Benedict XIV, the reigning pope. This may explain why he included a view of SS. Pietro e Marcellino in the book. It was a very minor ancient church, but one which the Pope had completely rebuilt in 1751.
SS. Pietro e Marcellino was located at the intersection of two important streets, but it was surrounded by villas (e.g. Villa Giustiniani Massimo) and farmed areas so that the view has a landscape atmosphere rather than an urban one. In the background Vasi showed SS. Quattro Coronati, a church which retained its medieval appearance.
The view is taken from the green dot in the small 1748 map below. In the description below the plate Vasi made reference to: 1) Street leading to Porta Maggiore; 2) Street leading from S. Giovanni in Laterano to S. Maria Maggiore (i.e. Via Merulana, aka Via Tabernola); 3) Street leading to Colosseo; 4) SS. Quattro Coronati. The small map shows also 5) SS. Pietro e Marcellino (before it was redesigned); 6) Sacello della Madonna; 7) site of Tempio di Iside. The dotted line in the small map delineates the border between Rione Campitelli (left) and Rione Monti (right).
The view in June 2010 (in the inset the roof of SS. Quattro Coronati)
Today the crossroad between the street leading to Colosseo and Via Merulana is very busy (the photo was taken on an early Sunday morning); when Vasi drew his etching the nunnery behind the church was yet to be built; it now obstructs (together with later construction) the view of SS. Quattro Coronati, of which only a roof can be seen. The small map shows that the section of Via Merulana leading to S. Giovanni in Laterano was very steep; in order to adapt it to modern traffic requirements the level of the ground near the church was raised so that today SS. Pietro e Marcellino is in a sort of a hole. Via Merulana was enlarged and S. Matteo, a small church which Vasi showed in his 1781 Map of Rome, was pulled down.
(left) Fašade; (right) dome
SS. Pietro e Marcellino was designed by Girolamo Theodoli, a nobleman and architect. He was Marquis of S. Vito and Earl of Ciciliano. The new church is indicative of the transition from Baroque to Neoclassical architecture.
The neat design of the fašade without the curved lines which were still in fashion at the time (e.g. in the new fašade of S. Croce in Gerusalemme), must have pleased Pope Benedict XIV. The Pope disliked some restorations of ancient churches, including the new loggia of S. Maria Maggiore, because of their excessive decoration.
The dome designed by Theodoli was instead a tribute to Francesco Borromini, the most innovative architect of the XVIIth century, because it resembles that of S. Ivo alla Sapienza.

Sts. Peter and Marcellinus were two martyrs of the early IVth century; a church was dedicated to them on the site where they were buried, three miles from Porta Maggiore; according to an inscription dictated by Pope Alexander IV in 1256 their bodies were relocated to their church inside Rome.
You may wish to see SS. Pietro e Marcellino as it appeared in a 1588 Guide to Rome. A 1674 rather detailed guide to the churches of Rome by Filippo Titi mentions the church, but without any references to works of art it contained or its architecture. Apart from the 1256 inscription the interior is entirely new.

Via dei SS. Quattro Coronati (the street to the right leads to Colosseo which is partly visible)
While SS. Pietro e Marcellino is today immersed in the noise and pollution caused by cars and buses, at a few hundred yards from this church, SS. Quattro Coronati still lives in its medieval past. Similar to S. Saba and other medieval churches it is protected by walls and its bell tower (the first of Rome) clearly had a defensive purpose.
(left) Medieval walls supporting the Benedictine monastery; (right) apse
Because two sides of the complex are built on the edge of a small elevation, the northern wall and the apse are supported by impressive substructures; in particular the wall of the apse retains masonry elements which indicate that the church was built upon a Late Roman basilica which probably belonged to a private house.
A reference to Titulus Sanctorum Quattuor Coronatorum has been found in the records of a 595 synod. In the IXth century Pope Leo IV largely restored the early church; according to art historians at his time the complex was composed of a large basilica preceded by an atrium, the entrance to which was protected by a tower.

and which were included into the wall of a Benedictine monastery
In 1084 Robert Guiscard sacked Rome and set fire to SS. Quattro Coronati; Pope Paschal II re-consecrated the church in 1116, but its size was reduced to the final part of the nave and the apse; the initial part of the nave was not rebuilt and it became the current inner courtyard of the complex; the aisles of the original basilica were included into a Benedictine monastery. The reconstruction of SS. Quattro Coronati was completed in the early XIIIth century by a fine cloister.

During the XIIIth and XIVth centuries the monastery was modified in order to house the residence of some powerful cardinals, including Cardinal Benedetto Caetani, who became Pope Boniface VIII in 1294.
In 1562 Pope Pius IV assigned the complex to Augustinian nuns, who still live there.

According to the prevailing tradition the saints to whom the church was dedicated were four sculptors who refused to work on a statue of Asclepius, Greek god of medicine, and who for this reason were put to death by order of Emperor Diocletian; the reference to Coronati (Crowned) is probably due to the fact that they were portrayed wearing wreaths symbolizing their martyrdom. Because of the trade of the saints the guild of sculptors (statuariorum) and stonecutters (lapicidarum) bought an oratory of the monastery in 1570. Eventually sculptors moved to Accademia di S. Luca, the guild of Roman artists, which at the beginning was reserved to painters only.

The interior of the church retains the 1621-627 decoration of the apse, but all other additions to the medieval church were removed in 1912-916.

Dante - Inferno - Canto XIX: 115-117
Ahi, Costantin, di quanto mal fu matre,
Translation by H. W. Longfellow
Ah, Constantine! of how much ill was mother,
Dante made reference to the Donation of Constantine, a document which claimed that Emperor Constantine donated the City of Rome and the entire Western Roman Empire to Pope St. Sylvester I. The poet was not supportive of the papal role in worldly affairs which originated from that decision by Constantine.

When the oratory was built relations between Pope Innocent IV and Emperor Frederick II were very tense and the frescoes which cover the walls of the building were meant to visually depict a cornerstone of the assumed supremacy of the Popes over the Emperors. The Donation of Constantine was eventually considered a forgery after Lorenzo Valla, a humanist, proved in 1440 that the Latin used in the document was inconsistent with that spoken in the IVth century.

The stonecutters' guild made some changes to the final part of the oratory and placed some marble inscriptions along the walls, but overall they did not damage the XIIIth century aspect of the building. You may wish to see a directory of churches and chapels belonging to guilds.
Frescoes on the rear fašade
(left) Sacello della Madonna and Via dei SS. Quattro Coronati; (right) sacred image
At the foot of the slope leading to SS. Quattro Coronati there is what is likely the most ancient
sacred image of Rome. It is located along the itinerary followed by the procession which accompanied the newly elected pope to S. Giovanni in Laterano for the formal ceremony during which he took possession of his post. According to a legendary account in the IXth century a female pope (Pope Joan) was caught by labour pains at this spot, her sex was discovered and she was stoned to death (see what happened in a 1600 illustration of a book by Johann Wolf - it opens in another window).
The madonnella is most likely a XVth century painting, but the existence of a sacred image located at this site is documented since the year 1000.

A madonnella in much better shape is located on an elegant XVIIIth century building near Sacello della Madonna and opposite S. Clemente.
(left) Tempio di Iside e Serapide; (right) statue of Isis found at the site and now at Centrale Montemartini
Regio III - Isis et Serapis, one of the fourteen regiones into which Rome was divided by Emperor Augustus, was named after a temple dedicated to these Egyptian deities. The exact location of the temple is uncertain, but today a large wall with niches is believed to have been a monumental fountain of one of the terraces which made up the temple. Its shape is assumed to have resembled Santuario della Fortuna Primigenia at Palestrina (on a smaller scale). It was most likely built in 80 BC by Consul and Pontifex Maximus Quintus Caecilius Metellus Pius which indicates that the worship of Egyptian deities by the Romans preceded the conquest of that country. It is referred to as Isium Metellinum to distinguish it from Isium Campensis, another large temple to Isis in Rione Pigna.

Excerpts from Giuseppe Vasi 1761 Itinerary related to this page:
Ne' primi secoli della Chiesa fu questa eretta, e poi da Gregorio III. rifatta; come pure da Alessandro IV., e finalmente da Clemente XI. fu conceduta a' monaci Siriaci di sant' Antonio. Il Pontefice Benedetto XIV. la rifece da' fondamenti col disegno del Marchese Teodoli e poi la concedŔ alle religiose di santa Teresa, che stavano presso s. Lucia alle botteghe oscure, dette le Ginnasie, le quali vi hanno fatto un ampio monastero, ed hanno ornata la chiesa con quadri moderni.
Incontro alla riferita chiesa, e sull'alto del colle si vede quella de' ss. Quattro Coronati, eretta da Onorio I. che fu del 630. nel luogo, ove i ss. Fratelli soffersero il martirio. Da san Leone IV. furono collocati in questa chiesa i corpi de' detti Santi con altri cinque corpi di ss. Martiri, e Pasquale II. vi aggiunse un gran palazzo, in cui per qualche tempo abitarono i sommi Pontefici; ma poi da Pio IV. vi fu adattato un conservatorio per le povere zittelle orfane, e vi si mantengono sotto la cura di alcune religiose Agostiniane, fino a tanto che prendano stato. Nel portico evvi una piccola chiesa dedicata a s. Silvestro Papa, che dalle pitture e memorie, che vi si osservano, sembra assai antica. La chiesa poi fu riattata ed ornata di pitture dal Card. Mellino Vicario di Urbano VIII. Prima di entrare in chiesa, sonovi alcune pitture a fresco credute di Raffaello da Reggio; nel primo altare a destra si vede la nativitÓ del Signore stimata del Naldini, e le pitture nell'altare del Crocifisso sono di persona ignota; quelle per˛ nella tribuna con diversi santi Martiri sono belle opere di Giovanni da s. Giovanni. Il s. Sebastiano dall' altra parte Ŕ del Cav. Baglioni, e la ss. Annunziata, del suddetto Giovanni.
