Telescopio / Galileo

Here’s a tiny version of the 1617 painting
Jan Brueghel the Elder’s telescopes…

A short note just arrived from Enrique Joven, concerning a recent talk he attended at the Instituto de Astrofisica de Canarias (IAC) by Dr. Paolo Molaro from the Osservatorio Astronomico di Trieste: “On the invention of the telescope and the paintings of Jan Brueghel

Jan Brueghel depicted telescopes in four paintings spanning the period between 1609 and 1621. We have investigated the nature and the origin of these telescopes. An optical “tube” that appears in the painting dated 1608-1612, and probably reproduced also in a painting of the 1621, represents one the earliest documentation of a Dutch spyglass which could even tentatively attributed to Sacharias Janssen or Lipperhey, thus prior to those made by Galileo. Other two instruments made of several draw-tubes which appear in the two paintings of 1617 and 1618 are quite sophisticated for the period and we argue that may represent early examples of Keplerian telescopes.

Molaro is (of course) referring to Jan Brueghel the Elder (1568-1625): before this, I had only heard of the telescope in the series of paintings Brueghel executed with Rubens (which is now in the Prado), so I look forward to reading more about the other depictions of telescopes, particularly the earliest of the set. Above iss a tiny version of the 1617 painting.
