Etymology

It is a New Latin coinage[1] from Ancient Greek τηλεσκόπος (tēleskópos, “far-seeing”),[2][1] a compound of τῆλε (têle, “far”) and a word for “watcher”.[2] Wiktionary takes it as a Latinisation of Italian telescopio, which Galileo coined in 1611.[1] Etymonline dates the Italian word to Galileo in 1611 and the New Latin one to Kepler in 1613, and adds that the name is said to have been coined by Prince Cesi, founder and head of the Roman Academy of the Lincei.[2]

Earliest recorded meaning

Etymonline credits Kepler with the New Latin word in 1613, for the telescope.[2]

Semantic evolution

It named the optical instrument that makes distant objects look nearer and larger.[2][1] English used the word in its Latin form from 1619,[2] and in 1752 La Caille gave the name Telescopium to a faint constellation.[2]
