When Tycho Brahe first saw the 1572 supernova in his night sky he was an astronomer moderately well-known for reputed feats of astrology and for building large observational instruments. Beginning fitfully, in 1568, he himself had been looking through those instruments, on nights when circumstances allowed, and carefully recording the positions of the stars and planets he observed.
A lack of dependable astronomical tables (a.k.a. ephemerides)
was beginning to be a problem. In part,
because they were needed in order to precisely cast the horoscopes that made
Tycho and other practitioners most of their reputation.
But it was also beginning to dawn on those practitioners
that Copernicus had changed our relationship to the heavens. In order to understand that change ever
greater precision was necessary. Patrons
wanted as much to be known to have underwritten verifiable theories regarding
the nature of the planets and stars. They
wanted to keep time more precisely, to calculate the trajectory of projectiles,…
and, yes, to read God’s messages in the sky.
Brahe’s math and mechanical skills being less than
exemplary, he increased the precision of his instruments — quadrants, at first — by making them large enough to accommodate
scales with graduations displaying fractional minutes of arc. The greater the precision
sought the larger the instrument had to be. Until he had tediously recorded the
positions of the objects in the heavens filling folio after folio for decades,
he was best known for these precise giants he created and the quality of his
observations upon the supernova.
When Brahe was encouraged by his friends and associates to
publish a book on the November 1572 supernova for which he is now famous, his
answer belonged to his times. It was
below the dignity of a nobleman to publish books.[1] He was also well aware that specialized texts
did not always fare well in the press.
His friends succeeded, however. He had made the most accurate instruments of
the time and could do parallax measurements that made clear that the supernova
resided beyond the Solar System in the region of the fixed stars. The fact that so much had been issued
throughout Europe about the star that was utterly inaccurate encouraged him to
set matters right. He even allowed his
name to appear on the titles page. A
tiny print run was issued in late 1573.
After seeing the book
through the press, in Copenhagen,[2]
he did what he enjoyed doing. He
traveled visiting universities and astronomers.
This time giving them copies of his book. He was doing an early form of a book
tour. As part of his tour, he traveled
to the great book fair at Frankfurt-on-Main.
In late 1575, the King of Denmark offered Brahe a small
island, near the royal castle of Elsinor, hoping that the privacy and
independence might attract him. It was
to come with a promise to build necessary buildings to the astronomer’s
specifications and with a healthy allowance.
The specific island the King was offering was the little
island of Hveen, near the royal palace of Elsinor. Brahe visited the island, on
February 22, 1576, like any other home buyer checking out the kitchen, the
plumbing, the neighborhood, etc. He must have found it acceptable as the following Royal proclamation
was published on May 23, 1576.
We, Frederick the Second, &c., make known to all men,
that we of our special favour and grace have conferred and granted in fee, and
now by this our open letter confer and grant in fee, to our beloved Tyge Brahe,
Otte's son, of Knudstrup, our man and servant, our land of Hveen, with all our
and the crown's tenants and servants who thereon live, with all rent and duty
which comes from that, and is given to us and to the crown, to have, enjoy, use
and hold, quit and free, without any rent, all the days of his life, and as
long as he lives and likes to continue and follow his studia mathematices, but
so that he shall keep the tenants who live there under law and right, and
injure none of them against the law or by any new impost or other unusual tax,
and in all ways be faithful to us and the kingdom, and attend to our welfare in
every way and guard against and prevent danger and injury to the kingdom. Actum
Frederiksborg the 23rd day of May, anno 1576.[3]
For his part, Brahe “the same [February] evening took his first
observation there of a conjunction of Mars and the moon.”[4]
This, presumably, by way of marking his
territory.
King Frederick was prescient to include the protections for
the tenants who lived in the tiny town called Tuna or “the toun”.[5]
Brahe was a proud man of minor noble stock and abrasive toward commoners who he
felt didn’t know their place. The twenty years that lay ahead would be punctuated
by conflict between them.
The map of the island of Hveen (“Insula Hvaena”) that forms
the left-hand panel of the illustration that leads this essay is getting ahead
of our story. Willem Janszoon Blaeu, a young student from Holland, traveled to
the island to volunteer as an assistant to the famous astronomer. He left to
return to his homeland on May 21, 1596,[6]
which is the only specific date we know regarding his stay which is said to
have come to a total of some two years. During his stay he drew a map of the
island and pictures of Brahe’s castle and many of Brahe’s instruments within.
Willem went on to become a famous publisher, mathematician
and cartographer. His son continued the publishing business, after his father’s
death. Atlases having become highly popular, he gathered his father’s maps and
those of others together in Le Grande Atlas published in 12 volumes
between 1662 and 1665. It is in the first volume that the Willem’s map of Hveen
appears.
