Eclipses
In 1560 an eclipse of the Sun took place which was total in Spain and
Portugal. Clavius who observed it at Coimbra says[90] that “the Sun
remained obscured for no little time: there was darkness greater than
that of night, no one could see where he trod and the stars shone very
brightly in the sky: the birds moreover, wonderful to say, fell down to
the ground in fright at such startling darkness.” Kepler is responsible
for the statement that Tycho Brahe did not believe this, and wrote to
Clavius to that effect 40 years afterwards.
In 1567 there was an annular eclipse visible at Rome on April 9. Clavius
says[91] that “the whole Sun was not eclipsed but that there was left a
bright circle all round.” This in set terms is a description of an
annular eclipse, but Johnston who calculated that at Rome the greatest
obscuration took place at 20m. past noon points out that the
augmentation of the Moon’s semi-diameter would almost have produced
totality. Tycho tells us that he saw this eclipse on the shores of the
Baltic when a young man about 20 years of age.
The total eclipse of February 25, 1598, long left a special mark on the
memories of the people of Scotland. The day was spoken of as “Black
Saturday.” Maclaurin states[92]:—“There is a tradition that some persons
in the North lost their way in the time of this eclipse, and perished in
the snow”—a statement which Hind discredits. The central line passed
from near Stranraer, over Dalkeith, and therefore Edinburgh was within
the zone of totality. Totality came on at Edinburgh at 10h. 15m. and
lasted 1m. 30s. From the rapid motion of the Moon in declination, the
course of the central line was a quickly ascending one in latitude on
the Earth’s surface, the totality passing off within the Arctic circle.
Kepler in his account of the new star in the constellation Ophiuchus[93]
refers to the total eclipse of the Sun of October 12, 1605, as having
been observed at Naples, and that the “Red Flames” were visible as a rim
of red light round the Sun’s disc: at least this seems to be the
construction which may fairly be put upon the Latin of the original
description.
The partial eclipse of the Sun of May 30, 1612, is recorded to have been
seen “through a tube.” No doubt this is an allusion to the
newly-invented instrument which we now call the telescope. Seemingly
this is the first eclipse of the Sun so observed, but it is on record
that an eclipse of the Moon had been previously observed through a
telescope. This was the lunar eclipse of July 6, 1610, though the
observer’s name has not been handed down to us.
