was the book containing the astronomical tables of Regiomontanus; and
from his study of this work he was aware that an eclipse of the moon was
due on a certain date near at hand. He sent his Indian interpreter to
visit the neighbouring caciques, summoning them to a great conference to
be held on the evening of the eclipse, as the Admiral had matters of
great importance to reveal to them. They duly arrived on the evening
appointed; not the caciques alone, but large numbers of the native
population, well prepared for whatever might take place. Columbus then
addressed them through his interpreter, informing him that he was under
the protection of a God who dwelt in the skies and who rewarded all who
assisted him and punished all his enemies. He made an effective use of
the adventures of Mendez and Porras, pointing out that Mendez, who took
his voyage by the Admiral's orders, had got away in safety, but that
Porras and his followers, who had departed in disobedience and mutiny,
had been prevented by the heavenly power from achieving their object. He
told them that his God was angry with them for their hostility and for
their neglect to supply him with provisions; and that in token of his
anger he was going to send them a dreadful punishment, as a sign of which
they would presently see the moon change colour and lose its light, and
the earth become dark.

This address was spun out as long as possible; but even so it was
followed by an interval in which, we may be sure, Columbus anxiously eyed
the serene orb of night, and doubtless prayed that Regiomontanus might
not have made a mistake in his calculations. Some of the Indians were
alarmed, some of them contemptuous; but it was pretty clearly realised on
both sides that matters between them had come to a head; and probably if
Regiomontanus, who had worked out these tables of figures and
calculations so many years ago in his German home, had done his work
carelessly or made a mistake, Columbus and his followers would have been
