rew his meridian line through the church of
St. Petronius in this city, across the pavement, where it still remains
a monument to his memory, who discovered the third and fifth satellites
of Jupiter. Such was in his time the reputation of a mineral spring near
Bologna, that Pope Alexander the Seventh set him to analyse the waters
of it; and so satisfactory were his proofs of its very slight importance
to health, that the same pope called him to Rome to examine the waters
round that capital; but dying soon after his arrival, he had no time to
recompence Cassini's labours, though a very elegantly-minded man, and a
great encourager of learning in all its branches. The successor to this
sovereign, Rospigliosi, had different employment found for _him_, in
helping the Venetians to regain Candia from the Turks, his
disappointment in not being able to accomplish which design broke his
heart; and Cassini, returning to Bologna, found it less pleasing than it
was before he left it, so went to Paris, and died there at ninety or
ninety-one years old, as I remember, early in this present century, but
not till after he had enjoyed the pleasure of hearing that Count
Marsigli had founded an academy at the place where he had studied whilst
his faculties were strong.

Another church, situated on the only hill one can observe for miles, is
dedicated to the Madonna St. Luc, as it is called; and a very beautiful
and curiously covered way is made to it up the hill, for three miles in
length, and at a prodigious expence, to guard the figure from the rain
as it is carried in procession. The ascent is so gentle that one hardly
feels it. Pillars support the roof, which defends you from a sun-stroke,
while the air and prospect are let in between them on the right hand as
you go. The left side is closed up by a wall, adorned from time to time
with fresco paintings, representing the birth and most distinguished
passages in the life of the blessed Virgin. Round these paintings a
little chapel is railed in, open, airy, and elegantly, not very
pompously, adorned; there are either seven or twelve of them, I forget
which, that serve to rest the procession as it passes, on days
particularly dedicated to her service. When you arrive at the top, a
church of a most beautiful construction recompenses your long but not
tedious walk, and there are some admirable pictures in it, particularly
one of St. William laying down his armour, and taking up the habit of a
