CHAPTER XII.

ECLIPSES OF THE SUN MENTIONED IN HISTORY.--
MEDIAEVAL AND MODERN.

One of the most celebrated eclipses of mediaeval times was that of August
2, 1133, visible as a total eclipse in Scotland. It was considered a
presage of misfortune to Henry I. and was thus referred to by William of
Malmesbury[80]:--

"The elements manifested their sorrow at this great man's last departure
from England. For the Sun on that day at the 6th hour shrouded his
glorious face, as the poets say, in hideous darkness agitating the
hearts of men by an eclipse; and on the 6th day of the week early in the
morning there was so great an earthquake that the ground appeared
absolutely to sink down; an horrid noise being first heard beneath the
surface."

This eclipse is also alluded to in the _Anglo-Saxon Chronicle_ though
the year is wrongly given as 1135 instead of 1133 as it certainly was.
The _Chronicle_ says:--"In this year King Henry went over sea at Lammas,
and the second day as he lay and slept on the ship the day darkened over
all lands; and the Sun became as it were a three-night-old Moon, and the
stars about it at mid-day. Men were greatly wonder-stricken and
affrighted, and said that a great thing should come hereafter. So it
did, for the same year the king died on the following day after St.
Andrew's Mass day, Dec. 2, in Normandy." The king did die in 1135, but
there was no eclipse of the August new Moon, and without doubt the
writer has muddled up the year of the eclipse and of the king's
departure from England (to which he never returned) and the year of his
death. Calvisius states that this eclipse was observed in Flanders and
that the stars appeared.

Respecting the above-mentioned discrepancy Mrs. Todd aptly remarks:--"So
