After completing the Last Judgment, Michelangelo
began work on a Conversion of
St. Paul fresco commissioned by the Pope
in 1542 for his Cappella Paolina. He finished three
years later, and shortly after began his The Crucifixion
of St. Peter fresco, which he completed in 1550.
In both of these works, which Michelangelo had difficulty executing
due to his declining health, he returned to the luminous color
of the Sistine ceiling while continuing with the flattened anti-perspective
he had explored in the Last Judgment. The Cappella Paolina frescoes
were to be Michelangelo's final paintings.
Michelangelo's Last Judgment was less
well received by religious figures than it was by artists, and
it inspired considerable controversy with the onset of the Catholic
Church's Counter-Reformation in the 1540s. One result of this effort
was that Neoplatonism was decreed heretical, meaning that nudes
in art could no longer be sanctioned by Christian doctrine. The
Council of Trent, the official summit meetings that outlined the
changes of the Counter- Reformation, decided essentially to prohibit
the use of the nude in religious art entirely, save for in a few
specifically noted scenes. In 1545 and again in 1550, the poet
Pietro Aretino accused the "godless" Michelangelo of desecrating
the Sistine Chapel by turning it into a whorehouse with his naked
figures. Michelangelo's public response to the criticism of Pope
Paul IV was vehement, but his private reaction was more vulnerable.
Michelangelo displayed increasing religious piety over
the years, and this change in religious feeling accounts in large
part for his switch from art to architecture late in his life.
In a 1554 sonnet written after the completion of his last painting,
Michelangelo wrote that "Neither painting nor sculpture will be
able any longer to calm my soul, now turned toward divine love."
In addition to Michelangelo's newfound piety, the deaths of some
of his closest friends and his growing physical incapacitation
overwhelmed him with a deep sense of shame and melancholy. In an
attempt to reconcile his love of art and his religion, Michelangelo
turned his attention almost exclusively to architectural projects
in the service of the Church. Of these, the most noteworthy was
the design and construction of St. Peter's. for which Michelangelo
would accept no financial compensation.
Ironically, during this dark period Michelangelo was at
the height of his fame–in 1550, Vasari published the first edition
of Michelangelo's biography in his Lives of the Artists, and
Condivi published his more accurate Life of Michelangelo in
1553. In 1545, Michelangelo's assistants finally completed the
tomb of Julius, but only a few figures in the piece are his and
he took little pride in the finished project. In 1547, Michelangelo
began working on one of his three final sculptures, the so-called Florentine
Pieta, which he intended for his tomb. However, after
the death of his faithful assistant Francesco Urbino, Michelangelo
tried to destroy the sculpture by smashing it with a hammer. Later
a student repaired it and continued work on it, but it remains
unfinished.
