Ibn Sid: Isaac ibn
Sid
Y. Tzvi Langermann
Ibn
Sid is believed to have played an important role in the observations and other
research sponsored by Alfonso X of
Castille, all of which bore fruit in the Alfonsine Tables. Some of
his observations are mentioned by Isaac Israeli, another Jewish astronomer
from Toledo, who worked nearly a century after Ibn Sid. Otherwise, nothing
is known about this figure.
