Although no one can ever be certain, elements of Rudolf II behaviour and personality are consistent with Asperger's Syndrome, a form of high IQ autism. Diamond Dave (8 November, 2005)

So he's like rainman. ROFL! -Alex, 12.220.157.93 09:27, 27 December 2005 (UTC)![reply]

No not like Rainman. Somewhat like the shy reclusive scientist Henry Cavendish or the more paranoid Sir Issac Newton. Rainman had low IQ (<75) severe autism, he did not have Asperger's Syndrome which is milder. See People speculated to have been autistic for more examples. Diamond Dave 16/02/2006 17:43

Anyone know why Rudolf II gets a "II" as his ordinal? He is the first Holy Roman Emperor and first ruler of Germany of that name. --Jfruh 16:25, 14 March 2006 (UTC)[reply]

There was a Rudolf I, the english wiki names him "Rudolph I of Germany", don't ask me why --81.10.162.27 19:28, 2 April 2006 (UTC)[reply]

Because he never was crowned Emperor (or proclaimed Emperor-eclect). He was the first Habsburg King. Str1977 ^{(smile back)} 18:55, 3 July 2006 (UTC)[reply]

Rudolf I was only king not emperor — Preceding unsigned comment added by 91.89.242.173 (talk) 07:50, 25 May 2014 (UTC)[reply]

The statement "He patronized natural philosophers such as the botanist Charles de l'Ecluse..."

seems inaccurate; or at least, inconsistent with the article linked to, on Carolus Clusius (latinized name of Charles de l'Écluse) which states "In 1573 ... he was appointed prefect (director) of the imperial medical garden in Vienna by Emperor Maximilian II (1564–1576) and made Gentleman of the Imperial Chamber. ... Clausius was discharged from the imperial court shortly after the death of Maximilian and accession of his son Rudolf II (1576–1612) in 1576."

Seems like Maximilian was L'Ecluse's patron, not Rudolph. The only mention of Rudolf II in the article on l'Ecluse is that he fired him shortly after becoming emperor.

I looked through Rudolf II and His World for where Clusius is mentioned, and you're right, he was in the cultural circles of the time, but never received patronage, so I removed that from the article. Unclevinny (talk) 16:55, 1 June 2025 (UTC)[reply]

In the photograph of a crown, a scepter, and an orb ("globus cruciger"), the caption says those are Rudolf II's. In other articles in Wikipedia (heresy! preaching that Wikipedia's internal self-contradictions can't all be true at the same time unless impeached by a source from outside Wikipedia!) it is stated that only the crown was made during his reign, the other two pieces made later.2600:1700:6759:B000:E10D:5CEF:D36B:9CF5 (talk) 19:48, 13 July 2025 (UTC)Christopher Lawrence Simpson[reply]
