How is an astrolabe a tool for measuring inclines? It can replicate the positions of the stars to give some information, but you couldn't use it to measure the angle of a hill's slope, as far as I know.
Geometry was 'revolutionized' by Euclid...it was already present in Indus Valley, Babylonia...there are many Vedic manuscripts about this and both Egyptians and Babylonians used forms of geometry...so it would be wrong to say that Greeks 'invented' geometry...
Euclid made it an actual science and documented its basic principles and axioms. What you suggest is like saying that Arabs didn't invent algebra because other peoples would count and perform addition or subtraction.
Hey QM, you‘ve made a mistake in this one. You wrote semicircular performance venue, which is clearly an indication of (and only of!) a theatre. An amphitheatre (Latin: amphi- meaning "to both sides") was something different - the Colosseum was an amphitheatre because it was extended to both sides (i.e. round). Why are the Amphibians called Amphibians? They can live in both kinds (land and water).

I thought the primary significance of the crossbow was not that it was more powerful than a traditional bow but rather that it was significantly easier to learn to use. From Wikipedia:
"The traditional bow and arrow had long been a specialized weapon that required considerable user training, physical strength and expertise to operate with any degree of practical efficiency. . . . In contrast, the crossbow was the first projectile weapon to be simple, cheap and physically undemanding enough to be operated by large numbers of conscript soldiers, thus enabling virtually any nation to field a potent force of ranged crossbowmen with little expense beyond the cost of the weapons themselves."
To me it seems weird not to accept it. It's not like it's a potential answer to any other clue, and clearly anyone typing it is referring to the alarm clock, commonly known as just an alarm including by Oxford, Cambridge, and Merriam-Webster
Maybe “travelled by a wheeled vehicle” might be more specific as surely surveyor’s wheel/trundle-wheel/hodometer/clickwheel/waywiser also/better fit the definition given. Also, is sextant not a valid answer for measuring inclines and making astronomical observations?
I guessed sextant at first too, but it doesn't seem that it was invented by the Greeks. From the wiki:
"The principle of the instrument was first implemented around 1731 by John Hadley (1682–1744) and Thomas Godfrey (1704–1749)"---who were English and American respectively.
Although weirdly both Hadley and Godfrey were known not for the sextant, but for the octant, which was the precursor to the sextant. In the wiki page for octants, Admiral John Campbell (again not Greek, but Scottish) is said to have suggested a larger instrument than the octant which then led to the creation of the sextant. He, however, is not mentioned at all on the sextant wiki page!
Theatron - place of viewing
Therefore - Amphitheatre is 'a theatre on both sides'
An amphitheatre is a circular theatre NOT semicircular
