bark". Dietrich provides eleven notes to Ibn al-Baitar's commentary and, as he does in all entries, attempts to identify the plant in modern nomenclature. In this instance, however, Dietrich says, "The plant's identification is very doubtful, perhaps impossible to know". And, he references his discussion of the plant in his Dioscurides triumphans. The reverse happens as well. As an illustration...

We introduce and study the partial singular braid monoid PSBn, a monoid that contains both the inverse braid monoid IBn and the singular braid monoid SBn. Our main results include a characterization of Green’s relations, a presentation in terms of generators and relations, and a proof that PSBn embeds in the semigroup algebra C[IBn].

This section 9.3 of Ibn Sı̄nā’s Qiyās is a commentary on sections 25 and 26 of Aristotle’s Prior Analytics i, pages 41b36–43a19. NB the parallel passage in Ibn Sı̄nā’s Burhān iii.2, p. 136ff (Badawi). The paper below is what Wikipedia would call a stub. I will add and correct as time allows. I make the paper available now because it contains a complete translation of Qiyās section 9.3, which is a...

In the last half century Ibrahim Madkour revolutionised the study of Arabic logic by making available a modern edition of the text of the Logic section of Ibn Sı̄nā’s Šifā’. Ibn Sı̄nā’s account of logic in the Šifā’ is much fuller than any of his other surviving accounts; it runs to some two thousand pages. It is also — in my view — more radical and more independent of Aristotle than his other ac...

The leg c , is called the hypotenuse. If no other number except one divides both a and b, then the triangle is called “primitive Pythagorean triangle” or just “PPT”. The smallest and best-known PPT is (3, 4, 5). Ancient clay tablets from Babylonia indicate that more than 1000 years before Pythagoras, the Babylonians demonstrated an awareness of at least 15 triangles. In ancient Egypt, the (3, 4...

impact on Ibn Tufayl's forerunners, especially Avicenna, whom Ibn Tufayl quotes expressly. Salim Kemal's 'Justifications of poetic validity' gives a very condensed summary of his monograph The poetics ofAlfarabi and Avicenna (Leiden, 1991). But I doubt whether Ibn Tufayl's novel kind of thought experiment can be grasped in terms of Avicenna's poetology. The medieval Latin translators did not co...
