Castelseprio e Monastero di Torba

Castelseprio (UNESCO 2011, rif. 1318) custodisce la più straordinaria enigma dell’arte medievale italiana — la piccola chiesa di Santa Maria Foris Portas (c.700 CE) con gli unici affreschi naturalisti del VII-VIII secolo sopravvissuti in Europa, attribuiti a un “Maestro di Castelseprio” ignoto la cui tecnica a pennello libero sembra anticipare di cinque secoli la pittura rinascimentale, e il vicino Monastero di Torba (VIII-IX sec. CE), oggi proprietà FAI, che unisce una torre di avvistamento romana del V sec. CE a un insediamento monastico femminile longobardo.

Castelseprio Santa Maria Foris Portas Monastero Torba (the most precisely Castelseprio zone Castelseprio Varese Lombardia Italy 45.7303 N 8.8768 E UNESCO WHS 2011 reference 1318: the complex (the UNESCO Castelseprio-Torba site includes 2 distinct monuments 1.5 km apart: (1) Santa Maria Foris Portas (the church “outside the gates” (the title “foris portas” indicates a position outside the defensive walls of the late Roman castrum of Castelseprio)); (2) the Monastero di Torba (the Lombard women’s monastery built into the remains of a Roman defensive tower)); the Santa Maria frescoes (the reason the site is UNESCO-listed: the fresco cycle in the apse of Santa Maria (c.680–700 CE): (1) the apse semi-dome: the Nativity scene (a major compositional cycle showing the Annunciation, Visitation, Nativity, Adoration of the Magi, Presentation in the Temple); (2) the style (the “Maestro di Castelseprio” (the anonymous painter to whom the frescoes are attributed): the technique is the most anomalous in European art history before the Renaissance: the painter uses a “free brush” technique (no preparatory underdrawing visible in X-ray analysis) that creates modeled forms with light and shadow in a way not seen in surviving European art until Giotto (c.1300 CE)); (3) the specific enigma: no comparable European paintings exist from the same period (650–750 CE); the closest parallels are in Coptic Egypt and early Byzantine art; the proposed explanations: (a) a Syrian or Alexandrian painter working in Lombard Italy; (b) a lost Lombard court tradition only partially preserved at Castelseprio; (c) a painter trained in a Byzantine center (Ravenna or Constantinople) who introduced a naturalistic Greek tradition into Lombardy; all 3 hypotheses remain unresolved).

Key facts

  • Il Maestro di Castelseprio: perché è il più grande enigma dell’arte medievale europea e le ipotesi sull’identità: the mystery (the mystery of the Castelseprio master: the frescoes were discovered in 1944 CE by the art historian Gian Piero Bognetti (1902–1963 CE) when a demolition team removing a plaster wall for wartime use accidentally revealed the paintings; the discovery (Bognetti saw the exposed paintings in October 1944 CE; he immediately contacted the Soprintendenza delle Belle Arti di Milano; the frescoes were protected with provisional sheltering until the liberation in April 1945 CE; the first scholarly publication: Bognetti, G.P. and others, “Santa Maria di Castelseprio” (Milano, Fondazione Treccani degli Alfieri per la Storia di Milano, 1948); the dating controversy (the frescoes have been dated variously from the 7th century CE to the 10th century CE: (1) 650–700 CE (Bognetti’s original dating; supported by the morphological similarity to the coins of Grimoald of Benevento (r.662–671 CE) engraved on the plaster above the apse (the coin images pre-date the fresco painting since they are in the lower plaster layer); (2) 750–800 CE (the dating based on stylistic comparison with the mosaics of the Haghia Sophia exonarthex (c.870 CE)); (3) 900–950 CE (the dating based on Carolingian metalwork parallels))); the technique (the specific anomaly: when art historians examined the Castelseprio frescoes with X-ray and infrared reflectography in 1995–1998 CE, they found NO underdrawing beneath the paint surface; all European fresco painters of the 5th–13th centuries used a “sinopia” (a red-earth underpainting) or a “cartone” (a paper template) to transfer the design to the wet plaster; the Castelseprio frescoes were painted directly on the wet plaster “a braccio libero” (freehand): a technique that was believed not to exist in European art before Raphael (1483–1520 CE))

History

Dal castrum romano ai Longobardi al ritrovamento 1944 CE al UNESCO 2011 (the most precisely Castelseprio zone history: the Roman castrum (Castelseprio (the Latin “Castrum Seprium”): a late Roman military camp established in the 4th century CE on a strategic hill (313 m) above the Olona valley in the area then called Seprio (from the Latin “saxum” = rock + “pratum” = meadow); the castle guarded the Alpine passes (the Via Varesina from Lake Maggiore to Milan); the Lombard conversion (569 CE: the Lombards (the Germanic tribe that invaded Italy in 568 CE under Alboin) captured Castelseprio in 569 CE and established a garrison; the Longobard Gastaldo (a local administrator appointed by the Lombard king) resided in the Torba tower (the Roman tower was converted to a residence and watchtower)); the monastery (the Monastero di Torba: the women’s monastery established in the Roman tower in the 8th century CE: the specific date is uncertain (the first documentary evidence of a Lombard women’s community at Torba is a 769 CE document from the Archivio Capitolare of Monza); the specific evidence at the tower (the tower has 3 floors of habitation; on the 3rd floor (the highest habitable level): frescoes of the 8th–9th century CE showing a row of nuns (the inscription beneath the nuns identifies them as “Anastasia, Giuditta, Ermengarda” and 4 other names; the nuns are depicted in prayer with their hands raised)); the destruction (1287–1290 CE: Ottone Visconti (1207–1295 CE; the Archbishop of Milan) destroyed the Lombard city of Castelseprio to punish its resistance to Visconti rule; the population was expelled; the church of Santa Maria and the Torba tower were abandoned; the frescoes were plastered over (the specific plaster layer: 1–3 cm of lime plaster that preserved the Lombard frescoes beneath until 1944 CE)); 2011 CE UNESCO serial inscription reference 1318.
