In the foreground of this 1754 etching Giuseppe Vasi showed a gentleman in the act of copying an ancient inscription; in the description Vasi explained that the stone was inside the Franciscan monastery. By using a magnifying glass it is possible to read the first words: Semoni Sanco Deo Fidius. The reason for Vasi's interest in this inscription lay in the belief that its content led St. Justin, a IInd century martyr, to conclude that a temple of Isola Tiberina was dedicated to Simon Magus, a Ist century sorcerer. The sin of simony, or paying for position and influence in the church, was named after him. Peter said unto him, Thy money perish with thee, because thou hast thought that the gift of God may be purchased with money (Act of the Apostles 8:20 - King James Version).
Semo Sancus was instead a deity of the Sabines and eventually of the Romans; in particular Semo Sancus was the god of oaths and it is thought that words like saint and sanction derive from Sancus.
The view is taken from the green dot in the small 1748 map here below. In the description below the plate Vasi made reference to: 1) Convento dei Padri Osservanti (Monastero Francescano); 2) Ponte Cestio; 3) Ponte Fabricio o Quattro Capi; 4) S. Gregorio a Ponte Quattro Capi; 5) Part of Rome. 2) and 3) are shown in detail in other pages.
The view in March 2010
In 1867 the column in front of the church was hit by a carriage and it fell and broke into many pieces; two years later Pope Pius
IX replaced it with a small monument to Sts. John of God, Francis, Bartholomew and Paulinus of Nola which was meant to celebrate the beginning of the First Vatican Council. The saints were chosen because of their links with buildings in this square.
In the 1880s the buildings to the right of S. Bartolomeo all'Isola were pulled down to enlarge the river bed and reduce the risk of floods.

According to the traditional account in 293 BC a temple to Aesculapius/Asclepius, god of Medicine, was built on Isola Tiberina on the site where a sacred snake brought to Rome from the god's shrine at Epidaurus, hid itself; at that time the Romans were increasing their links with Greece and adding Greek gods to their own.
In the historical section of this website you can see a well of the ancient temple and a relief which most likely portrayed Asclepius (a detail is shown in the image used as background for this page).
In the 1880s a major effort to lower the river bed led to finding many small terracotta reproductions of parts of the human body. They were ex-votos and they came from the ancient temple (you may wish to see a collection of similar ex-votos which were found in Corinth).

A church which made use of some structures of the temple was built in ca 1000 by Emperor Otto III to house an arm of St. Adalbert of Prague, his friend and adviser, who died while trying to convert the Baltic Prussians; the church was dedicated to St. Bartholomew and other martyrs.
The bell tower was built in ca 1113 and in the following century the fašade was embellished with mosaics and the interior with a Cosmati pavement.
In 1557 a major flood destroyed one side of the church and its fašade; for some time the building was abandoned and only in 1583 it was partially restored (you may wish to see it in a 1588 Guide to Rome). In 1624 S. Bartolomeo all'Isola was almost entirely rebuilt (perhaps by Martino Longhi the Elder) by order of Pope Urban VIII. The interior, including the ceiling, was partly redesigned in the XIXth century.

Notwithstanding reconstructions and restorations the church retains some elements of its early days. The columns do not have their original capitals, but their shafts stand on ancient plinths, although there is a mismatch between the two. In the XVIIIth century most of the Cosmati pavement was removed, probably because it was damaged by floods.

In 1513 Pope Leo X assigned S. Bartolomeo all'Isola to the Franciscan Order. The monastery included some medieval buildings, but its interior was redesigned in the XVIIth century. For a certain period of time the meetings of a brotherhood were held in the monastery. The brotherhood (Confraternita dei Devoti di Ges¨ al Calvario) took care of burying the bodies of the drowned; its members were known as Sacconi Rossi after the large red robes they wore. Every year on All Souls' Day they went in procession to the tip of the island (opposite Ponte Rotto) where they threw a wreath into the river in memory of the drowned whose bodies were never found.

The medieval tower shown above was part of a larger fortification system which for a period of time belonged to the Pierleoni, who controlled the passage through the island (see their nearby houses). It was acquired by the Caetani, the family of Pope Boniface VIII. In 1638 the tower became part of the monastery.

According to tradition a medieval church was built on the house were St. Gregory the Great was born; as a matter of fact the ancient walls which have been unearthed under the current building were part of Teatro di Marcello. In 1555 when Pope Paul IV forced the Jews to live inside the Ghetto, S. Gregorio a Ponte Quattro Capi acquired importance because it was located immediately outside the eastern gate of the Ghetto; on Sundays
the Jews had to attend masses or to listen to sermons inside the church.
In the XVIIIth century the church was redesigned by Filippo Barigioni.
According to Luisa Scalabroni (Giuseppe Vasi 1710-1782 - Multigrafica Ed. - Roma 1981) Giuseppe Vasi was buried in S. Gregorio a Ponte Quattro Capi, although his son Mariano put his portrait and an inscription celebrating him in S. Caterina della Ruota.
Inscription quoting a sentence of Isaiah 65: "I have spread out my hands all the day unto a rebellious people, which walketh in a way that was not good, after their own thoughts. A people that provoketh me to anger continually to my face (King James Version)". Originally the inscription was painted, but in 1858 Pope Pius IX had it engraved on marble
Excerpts from Giuseppe Vasi 1761 Itinerary related to this page:
Da principio fu questa chiesa dedicata a s. Adelberto martire; ma poi nell'an. 983. essendovi dall'Imperatore Ottone III. trasportato, fra gli altri il corpo di s. Bartolommeo Ap., a questo fu dedicata. Risedeva quý nel palazzo contiguo il Vescovo di Porto, e come in sua Diocesi amministrava i Sagramenti, e per˛ fu collegiata; ma poi nel 1513. essendo conceduta ai frati Osservanti di s. Francesco, questi convertirono il palazzo in convento. Nell'urna di porfido sotto l'altare magg. ornato con quattro colonne similmente di porfido si conserva il corpo del s. Apostolo, e nel pozzo incontro furono trovati i corpi di s. Paolino vescovo di Nola, di s. Essuperio, e di s. Marcellino confessori, con altri Santi. Nel piccolo chiostro si vede affissa al muro la lapide ritrovata nello scavare presso questa chiesa nel Pontificato di Gregorio XIII. la quale ha dato motivo ad alcuni dr dire, che s. Giustino martire abbia sbagliato quando asserisce, che in Roma fosse stata la statua di Simon Mago eretta da' Romani inter duos pontes: ma ci˛ Ŕ avvenuto perchŔ non avvertirono, che il sito chiamato dagli antichi inter duos pontes era quello, come dicemmo, che restava tra il ponte Sublicio e il Senatorio, e non questo fra li due ponti dell'isola. Eĺ certamente venerabile il sito intorno a questa chiesa; mentre quý presso si tiene da alcuni, che anticamente fossero le carceri pubbliche, vicine al fiume, ed in luogo pi¨ separato dalla CittÓ, e perci˛ sicuro. ComecchŔ in esse erano poste le persone pi¨ vili, e di tal condizione essendo in quei tempi stimati i Cristiani da' Gentili, perci˛ furono santificate colla stentata, e penosa dimora, che vi fecero molti santi Martiri, ed in particolare s. Quirino, di cui trovasi fatta menzione negli atti de' ss. Mario, Marta e loro figliuoli Persiani, i quali venuti da paesi cosý lontani per venerare i sagri Limini, ed i luoghi santi di Roma, con una fervente caritÓ, e viva fede andavano cercando e consolando i poveri Cristiani carcerati; e leggesi che vennero a questa prigione di Trastevere, e trovando in essa s. Quirino con molti altri fedeli, vollero fermarsi nella prigione per otto giorni, servendoli e lavando loro anche i piedi, con gettar quell'acqua per devozione sopra i corpi loro, e de' loro figliuoli. Questi dopo gli otto giorni, essendo andati a seppellire altri santi Martiri nella via Salara, quando ritornarono alla prigione, non vi ritrovarono s. Quirino; ed avendo inteso da un prete chiamato Pastore, che la notte era stato ucciso, e gettato nel Tevere, ma che il corpo era stato arrestato nell'istessa Isola, essi la notte seguente lo presero, e lo seppellirono nel cimiterio di Ponziano. Moltissimi altri simili fatti si leggono; ma per non prolungare pi¨ oltre il viaggio di questa giornata, a bella posta si tralasciano.
Dirimpetto ai due portoni del Ghetto sta questa piccola chiesa, la quale essendo nel Pontificato di Benedetto XIII. riedificata, vi fu dipinto sopra la porta il s. Titolare genuflesso a piedi del ss. Crocifisso, e sotto vi furono posti alcuni versi della Scrittura, che rimproverano la perfidia ed ostinazione degli Ebrei. Fu conceduta questa chiesa alla Confraternita della divina PietÓ, la quale ha per istituto di ajutare le povere famiglie civili.
