Eight Qarakhanid triangles

[Pellinore]

That infinitely interesting Qarakhanid dynasty continues to fascinate me. I now have eight Qarakhanid fals with a triangle (six different). Here they are. From left to right and top to bottom:
Kharashket AH 409 (=AD 1018-1019) - Ferghana 386 - Ilaq 409
Ferghana AH 387 (= AD 997) - Ferghana 386 - Bukhara 414
Bukhara AH 494 (= AD 1101), twice

Great series, Pellinore! Ogled them like stewardesses on a long flight . I notice the playful positioning of the circle within the triangle. Early mathematicians looked for divine messages in mathematics and this would have appealed to them as it appeals to the symbolist in me.
