In the middle is the altar of the beautiful
18th-century church of Santa Maria Assunta (aka,
the Gesuiti), in Venice; it's flanked by two
plants I saw last Sunday. Wonder where
Fra Giuseppe Pozzo got the idea for his altar.
(Well, he probably got it from Bernini's
17th-century baldachino in St. Peter's, which is
also supported by spiral-shaped
pillars)—but they were both clearly inspired
by nature, the ultimate source of all beauty.
