Maybe you're different, but I don't expect to be struck by sudden pangs of sadness when I browse the US Naval Oceanography Portal's small rare book selection.
Johannes Hevelius was a 17th century Polish master brewer and astronomer. He built a giant viewing platform across the roofs of his three adjoining houses in Gdansk to hold his awesome array of astronomical instruments, including a giant 45m focal length Keplerian telescope and massive sextants of his own design and fabrication. It was considered the best-equipped observatory in the world, and Hevelius and his wife/collaborator Elisabeth received successive kings and queens of Poland, as well as international colleagues like Edward Halley.
Anyway, here is LSM's catalogue description of Helevius's Machinae coelestis pars prior [published in 1673] and pars posterior :
The first volume, lavishly illustrated, describes his instruments. Some plates show his wife, assisting him with the observations. The second volume, which gives his observations from 1630 to 1679, had just been returned to him by the printer, when a fire burned down Hevelius' house, destroying his instruments, library, and almost the whole edition of this work. Only a few copies survived, which had previously been sent to personal friends.Wikipedia uses the phrase "maliciously destroyed," but offers no details. Perhaps someday a novelist will tell us what happened.
Hevelius later named the equatorial constellation Sextans after his lost instruments.
The Naval Oceanography Portal has several large images of Hevelius's set-up. [usno.navy.mil, via a bibliodyssey tangent]
