The title states that this text is an excerpt from an Arabic version of the Conics (Κωνικά; in coniferous forms) by Apollonius of Perga (Ἀπολλώνιος; Apollonius; fl ca 200 BC). The
colophon
Section at the end of a manuscript text.
, however, gives the title of the work as the
Book of Burning Mirrors and Compendium of Conics
(The Book of Burning Mirrors and Collections of Cones), and states that it was copied in Dhū al-Qa‘dah 639/May 1242 from an exemplar copied in ‘the west side of the city of Mahdīyah (in the Maghrib district of the city of Mahdia)’ on 11 Rabī‘ I 531/7 December 1136 (see
colophon
Section at the end of a manuscript text.
f. 172v, lines 11-16, transcribed below).
The text contains fifteen diagrams.
Appended to the text is a note on division and multiplication using Arabic (hindī) numerals that the scribe claims to have found in his exemplar.
Begins (f. ff 164v, lines 3-6):
If a straight line connects a point to a line surrounding a circle and it is not the point on the surface that...
It has the circle, not the point, with the end of the line in place, and I rotate the straight line on the line
What surrounds the circle until it returns to the position from which it began to move, then name the shape it contains
This line has a pine shape...
Ends (f. 172v, lines 6-8):
...They use that piece
The edge of which is the diameter of the side of a gun, and the best thing to burn with is burnt glass
It was not a perfect ball, like a large ball of water, and it should be filled with water
Colophon

(f. 172v, lines 9-18):
Burning mirrors and mosques were written
Cones, praise be to God and from Him
I copied it from a copy that was written in the Morocco region
In the city of Mahdia and the date of its capture
The first ten days of the month of Rabi` al-Awwal
In the year five hundred and thirty-one
Hijri and I quoted it in the middle ten
From Dhul-Qi'dah in the year 639
Praise be to God, the Grantor of reason
