Artist gets noticed

An artist asked the gallery owner if there had been any interest in his paintings on display at that time.

"I have good news and bad news," the owner replied. "The good news is that a gentleman enquired about your work and wondered if it would appreciate in value after your death. When I told him it would, he bought all 15 of your paintings."

"That's wonderful!" the artist exclaimed. "What's the bad news?"

Georg von Peurbach

Born 30 May 1423; died 8 Apr 1461 at age 37.Austrian mathematician and astronomer who promoted the use of Arabic numerals (introduced 250 years earlier in place of Roman numerals), especially in a table of sines he calculated with unprecedented accuracy. He died before this project was finished, and his pupil, Regiomontanus continued it until his own death. Peurbach was a follower of Ptolomy's astronomy. He insisted on the solid reality of the crystal spheres of the planets, going somewhat further than in Ptolomy's writings. He calculated tables of eclipses in Tabulae Ecclipsium, observed Halley's comet in Jun 1456 and the lunar eclipse of 3 Sep 1457 from a site near Vienna. Peurbach wrote on astronomy, his observations and devised astronomical instruments.[Image: from Epitome of the Almagest.]
