You can read more about animals with large eyes in The Most Powerful Eyes. https://read.cash/@Mictorrani/the-most-powerful-eyes-9dc49a42 The first right answer came from @MD_Tibro. @Adobe101 also suggested it. https://read.cash/@MD_Tibro https://read.cash/@Adobe101 Answer to Quiz 8:2 “*One Roman emperor is most known under his nickname, which means "little boot"; who was his father?”* This is a question in two steps. "Little boot" was **Caligula**, from *caliga*, soldier's boot. He was Roman Emperor 37-41 AD, and is known as one of the most cruel and perverted Roman emperors. Caligula was a nickname, his real name was Gaius Caesar Augustus Germanicus. His father was Roman general **Germanicus Julius Caesar**, the adopted son of Emperor Tiberius. Answer to Quiz 8:3 “*Which powerful Germanic tribe during the great migration in Europe got its name from a certain growth of hair? A form of their name is sometimes still associated with banking.* *They founded a mighty kingdom in present day Italy, and their name still survives in the name of an Italian region.“* It was the **Langobards**, also known as **Lombards**. Langobard means "long beard". Originally from Southern Sweden in Scandinavia (probably), they migrated through Europe and ended up founding a powerful kingdom in present day Italy. The association with banking is "Lombard banking", pawn shops, which as far as is known were originating in **Lombardy** in Northern Italy. Some cities still today has a Lombard Street, originally a banking street or a pawn shop street. Answer to Problem 8:4

*And now some new exercises for brain & memory...* Quiz 9:1 One of the most well known knights of world literature, probably THE most well known, a figure being a bit ridiculous, stems from a place also being known for the cultivation of a certain spice. 3 questions: What spice?

One of these quotes is a clue. “[...] *out of love of symmetry, just as people put two vases above a fireplace.*” (Guy de Maupassant, *Bel-Ami*) “*Don't confuse symmetry with balance.*” (Tom Robbins, *Even Cowgirls Get the Blues*) “*If you look at music, you see theme, variation, you see symmetry, asymmetry, you see structure, and these are related to skills in the real world.”* (Dave Van Ronk) *“Our notion of symmetry is derived form the human face. Hence, we demand symmetry horizontally and in breadth only, not vertically nor in depth.*” (Blaise Pascal) **You'll find answers and solutions in the next “Quizzes & Puzzles”.** Quizzes & Puzzles has now its own label in my Index, where all issues of the series can be found. https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34#quizzes-amp-puzzles **In my** **INDEX****, you can find all my writings on Read.Cash, sorted by topic.** https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34 Copyright © 2022 Meleonymica/Mictorrani.
