Eise Eisinga’s planetarium, Franeker. The oldest planetarium in the world!

  1. Isn’t that in some house or old church or something, in the attic? I actually have been near it, but had no time to visit.

  2. And then if you see this, realise that this guy did not had any education at all. But he liked mathematics and wrote his own mathematics book on an early age.
    His wife was done after a few years and gave him an ultimatum for finishing it.

    The nails and stuff where it’s made with are still original.

    His inspiration came from that people were superstitious about most of the planets in a line, which should bring Doomsday. With his mathematics knowledge he would show to people that planets in line will happen once in a while, because that’s how the universe works.

  3. Small correction: *The oldest **working** planetarium in the world!

    I stumbled upon it while driving through Friesland, and it’s definitely one of the coolest things I’ve visited in the Netherlands. Highly recommended!

  4. >oldest planetarium in the world!

    Is de world dan zo klein? Beperkt de world zich tot Nederland? Lijkt me dat er elders op deze aardkloot toch wel een ouder exemplaar te vinden is?

    Indrukwekkend desalniettemin!

  5. Geweldig om constant nieuwe interessante plekken te ontdekken in eigen land. Ik had hier nog nooit van gehoord, maar ga het zeker een keer bezoeken.

  6. Wasn’t this clandestine as well, because it went against church doctrine or something like that? Or am I misremembering something?

    Edit: I can’t find anything about it, so I must be mistaken. Maybe I’m just thinking of Galileo, although I could have sworn there was a similar story associated with this.

  7. I’ve been there a couple of weeks ago, it is really amazing!

    The planetarium even includes a user manual in which includes maintenance such a moving a specific planet one gear back/forth once every 30 years or so.

  8. In the diary of Jacob van Lennep, he tells about visiting Eise Eisinga and the planetarium when he is in Franeker. At one point Van Lennep says something along the line of “it’s a pity it has to be broken down at some point”.

    I always thought it funny that a guy was afraid people wouldn’t attempt to protect the planetarium.

    Edit: [looked it up](https://www.dbnl.org/tekst/lenn006mekl01_01/lenn006mekl01_01_0005.php) here’s the full quote:

    >Eenige grachten verder, traden wij de eenvoudige woning van den wolkammer EISE EISINGA in. Deze kwam met een schortkleed voor en leidde ons in een klein kamertje, waar wij boven ons hoofd het gansche planetenstelsel zagen. Alle planeten hier afgebeeld bewegen zich werkelijk als in de natuur en volbrengen hun loop in denzelfden tijd, alsook al hunne manen. Vier andere platen wijzende op- en ondergang van zon en maan aan; andere weder de schijnbare zonsbeweging; de lichtgestalte der maan; de afstand der aarde van de zon; die der maan van de noord- of zuidpolen; de dagen der maand, der week, het uur, de minuten en seconden; ook het jaargetal, de N. en Z. declinatie enz.
    >
    >Dit alles wordt door een slinger in werking gebracht. De raderen en pennen zijn slechts van hout en beslaan geen meer plaats dan het platfond boven het kamertje tegen I½ voet hoogte. De maker toonde mij alles als was hij in een kermisspel, zonder dat hij er iets van scheen af te weten. Wij wisten niet wat meer te bewonderen, de trotschheid der onderneming, de voortreffelijke juistheid der uitvoering of de onbegrijpelijke eenvoud van den vervaardiger; jammer dat dit kunstgewrocht niet te verplaatsen is en met het huis vergaan moet.

  9. Unfortunately for him it was only complete for a couple of months. Shortly after he finished, they discovered Uranus.

  10. Next to the Planetarium is the Planetarium Cafe. This belonged to my great grandparents who used to live there and had a shop where they sold coffee/tea and jewelry from Asia, vases etc. In the ‘achterhuis’ from the Planetarium is where they celebrated birthdays and held party’s.
    My grandmother still has a lot of stuff from there. Every now and then I can pick something out of her collection ☺️

  11. My grandma used to take me on trips through Friesland when I stayed for some time with her during holidays, when I was around 10 I was very interested in planets and space and she took me here, and to the observatory in Burgum.
    Very nice memories.
    Still miss her <3

  12. The awesome thing is also, he knew he made some little ‘mistakes’. He wrote them all down on paper, very precisely. They still use this as a way to make it work like it supossed to be. Also Uranus was just discovered months after finishing the planetarium. That frustrated him so much he wanted to build a new one, but never did. They applied for an Unesco World Herritage. Pretty interesting tour it was

  13. Born and raised Dutchie here and I was made aware of this great bit of history by my American cousins who couldn’t wait to visit it.

    I felt like such a twat / “Culture Barbarian”.

  14. Ooh yeah, i went there very recently. I thought it was very beautifull especially because you can actually see the whole mechanism still working upstairs!
