I am searching for the actual text to the philosophic questionnaire Frederick II of Hohenstaufen, King of Sicily and Jerusalem, sent out in1240 which was answered by Ibn Sabin of Ceuta, originally of Murcia.

It concerns the immortality of the soul, the eternity of matter and other issues, apparently of Aristotelian origin.

I can find only references to the contents of Frederick’s questionnaire, not the exact questions.

I can find nothing Ibn Sabin’s responses.

Both Frederick’s questions and Ibn Sabin’s answers, of course, may not be extant. They may exist only in Arabic.

Any help on this would be appreciated.
