Ferrara: Centro Storico e Delta del Po
Ferrara (UNESCO 1995, Delta del Po aggiunto 1999) è la prima città pianificata del Rinascimento italiano — l’Addizione Erculea di Biagio Rossetti (1492 CE) ha raddoppiato la dimensione di Ferrara con un piano urbano con strade dritte, isolati regolari e giardini pensati prima di costruire, un metodo che sarà codificato teoricamente solo nel XVII secolo ma che qui fu realizzato con 150 anni di anticipo su qualsiasi altra città europea.

Ferrara centro storico (the most precisely Ferrara zone Ferrara Emilia-Romagna Italy 44.8374 N 11.6191 E UNESCO WHS 1995/1999 reference 733: the Addizione Erculea (the specific plan: the Addizione Erculea (the “Herculean Addition”): the urban expansion of Ferrara commissioned by Ercole I d’Este (1431–1505 CE; Duke of Ferrara 1471–1505 CE) and designed by Biagio Rossetti (c.1447–1516 CE): (1) scale: the existing medieval Ferrara was approximately 40 hectares; the Addizione Erculea added approximately 80 hectares (doubling the urban area; the population increase from c.30,000 to c.100,000 was anticipated in the plan); (2) the street layout: the Addizione Erculea introduced straight boulevards (the Corso degli Ercole d’Este and the Via dei Prioni: both over 800 m long and 12–14 m wide; wider than any medieval Italian street and designed for wheeled traffic and cavalry); (3) the Quadrivio degli Angoli (the “Corner Crossing”): the intersection of Corso degli Ercolani and Via Voltapaletto: the 4 corner palaces (Palazzo Prosperi-Sacrati, Palazzo dei Diamanti (later the Pinacoteca Nazionale), Palazzo degli Angeli, and the Palazzo Turchi di Bagno) were designed by Rossetti as a coordinated ensemble (the first time in Europe that 4 independent private palace facades were designed by a single architect to form a coordinated urban space); the Palazzo dei Diamanti (Biagio Rossetti, c.1492–1503 CE): the most famous building of the Addizione Erculea: the facade (255 marble ashlars cut in diamond points: 8,500 diamonds total; the marble is the “Aurisina” limestone from the Trieste karst; the diamonds reflect light differently at different times of day (dawn: the points cast horizontal shadows; midday: the diamond faces gleam uniformly; evening: the points cast long vertical shadows)); the specific optical illusion (Rossetti cut the diamonds in 3 different sizes at the corners, middle, and base of the facade to compensate for the perspective distortion of a viewer at street level: the diamonds appear uniform in size from any point of view on the street — the first calculated optical correction of a building facade since Vitruvius described the technique in the 1st century BCE)).
Key facts
- Il Salone dei Mesi nel Palazzo Schifanoja (1469–71 CE) e il ciclo astrologico-cortigiano più completo del Rinascimento italiano: the Palazzo Schifanoja frescoes (the Salone dei Mesi (the “Room of the Months”): the main hall of the Palazzo Schifanoja (the Este summer palace; Via Scandiana 23; open Tue–Sun 9:30 AM–6 PM; €8); the fresco programme (designed by court astrologer Pellegrino Prisciani; executed 1469–71 CE by a team of Ferrarese painters (attributed to: Cosmè Tura (March; July; possibly others); Francesco del Cossa (the March, April, and May panels; the most complete and best-preserved; signed in an inscribed letter to Ercole d’Este requesting higher pay: “the work I have done should be valued higher than that of the common shop painters”); Ercole de’ Roberti (various panels)); the 3-tier programme (each month panel has 3 horizontal tiers: (a) the upper tier: the classical myth assigned to the month (March = Minerva with weavers; April = Venus with lovers; May = Apollo with a chariot race); (b) the middle tier: the astrological decans (the 3 “decans” (10-day sections) of each zodiac month; each decan has a specific appearance and attribute (the decan figures are copied from Arabic astrological manuscripts (the “Picatrix” and the “Albumasar”) via Ferrarese Latin translations)); (c) the lower tier: the court of Ercole I d’Este in contemporary 1469 CE clothing (the triumph of the month: the Duke receives a delegation; hunts; plays chess; the specific identification: the figure in the March panel in the lower tier showing a man on horseback carrying a hawk (a falconer) on his wrist is identified by the heraldic device on his doublet as Ercole d’Este himself — the only contemporary portrait of the Duke in the entire cycle))
