Antonio di Pietro Averlino (c. 1400 - c. 1469), also "Averulino",
dubbed Filarete (Greek "lover of virtue"), was a Florentine
architect, sculptor and architectural theorist of the Italian Renaissance.
"Filarete",
as he is universally known, worked, and was probably born, in Florence,
and may have trained under Lorenzo Ghiberti. Under a commission by Pope
Eugenius IV, Averlino, over the course of twelve years, cast the bronze
central doors for the old St Peter's Basilica in Rome, completed in 1445;
in the work Filarete hoped to rival Ghiberti's great bronze doors for the
Baptistery of Florence. In the following century, Filarete's doors were
preserved when Old St Peter's was demolished and reinstalled in the new St
Peter's Basilica.
Leaving Rome for the patronage of Francesco Sforza in Milan, Averlino
built the Ospedale Maggiore (from ca 1456), which was rationally planned
as a cross within a square, with the hospital church, itself
centrally-planned, at the center of the plan. Surviving original sections
of the much-rebuilt structure show the Gothic detail of Milan's
quattrocento craft traditions at odds with Filarete's design all' antica
(Murray 1963). He also worked on the Castello Sforzesco, and on the Duomo
di Milano.
In ca. 1465 Averlino completed his Trattato di architettura
("Treatise on Architecture") in 25 volumes, which circulated
widely in manuscript. A profusely illustrated manuscript of the Trattato,
the Codex Magliabechiano, of ca 1465, dedicated to Piero de' Medici and
conserved in Florence, suggests that Filarete had fallen out of favour in
Milan soon after completing his Trattato. The style which Filarete called
the "barbarous modern style", which he urged his readers to
abandon, is the Gothic style of Northern Italy. Much of the treatise, in
the favoured form of a dialogue— here between the patron and his
architect— is a detailed account of an imaginary and somewhat magical
city, Sforzinda, named to honour Filarete's patron. The city. which he
compared to an ideal human body, was inscribed within an eight-pointed
star of walls inscribed within a perfect circular moat, the first of many
ideal star-shaped city plans that reacted against the crowded, irrational
spaces of the medieval city. Eight towers were placed as bastions at the
salient points of the star, and eight gates were the outlets of radial
avenues that each passed through a market square, dedicated to certain
goods. Other radiating streets had the parish churches and convents on
them. A canal system connected with the river and the outside world,
provided transport for goods. At Sforzinda's centre was the formally
composed piazza, a double square that was a stadio long and half a stadio
wide, with the duomo at its head, and a lookout tower. Sforzinda's
buildings and their highly symbolic decor were minutely described, and the
astrological calculations required for harmony, together with thoroughly
practical matters concerning fortifications, with the discovery of a
Golden Book detailing the buildings of Antiquity. The aspects of Late
Gothic courtly Romance in a treatise on architecture were not to the taste
of more rational 16th century taste that followed: Giorgio Vasari
dismissed Filarete's treatise as "most ridiculous and perhaps the
stupidest book ever written." The first publication of Filarete's
Tractatus had to wait until the Codex Magliabechiano, manuscript was
edited by W.von Ottigen, in 1894.
