He was known as the "absent-minded professor of Gotha". He died in Gotha, aged 77. Some Kathederblüten of Galletti :
* After the Battle of Leipzig you could see horses with three, four, or even more legs shot off running loose all over the countryside.
* Deiotarus was his father's son.
* Indeed, Councillor, I am well pleased with Blädner, but with Seifert not at all; but at least he's better than Blädner.
* So you think that history is as easy as playing Snap? Ha! You can learn history in a flash, but learning Snap takes years of hard graft.
* The African Lion usually grows up to the age of ten, and from then on, its size simply increases.
* Alexander would have gone on to conquer all Asia; but he's going to die soon.
* And thus, there ensued an entire war on page 94.
* I've exited the monk too early. His exit doesn't come earlier than right now.
* Today, I'm once again seeing so many students that aren't there!
* Watch out, I'm going to slap you if you aren't disobedient at once!
* Charlemagne won as often against the Saxons that in the end they wouldn't even wait for it any-more.
* Among the masterpieces of Demosthenes, we have his celebrated speech on the wreath. This speech is well known to begin with the immortal words: "Which rascal is throwing spit wads here again?"
* And you, Schäfer, you don't belong amongst decent people at all. Come to me at the lectern in front.
* The Persians cried out loud: "Good Lord Jesus, the Athenians are coming!" and threw themselves into the sea.
* The Venetian constitution is a mixed aristocracy which it is very difficult to get out of again.
* The pig is justly named that way, for it is a very dirty animal.
* The soldiers threw their weapons away and said: "pardon [me]". ( "ask for pardon" means "ask for quarter" in German)
