- Circinus (Wikipedia)
Circinus is a small, faint constellation in the southern sky, first defined in 1756 by the French astronomer Nicolas-Louis de Lacaille. Its name is Latin for compass, referring to the drafting tool used for drawing circles (it should not be confused with Pyxis, a constellation that represents a mariner’s compass which points north). Its brightest star is Alpha Circini, with an apparent magnitude of 3.19. Slightly variable, it is the brightest rapidly oscillating Ap star in the night sky. AX Circini is a Cepheid variable visible with the unaided eye, and BX Circini is a faint star thought to have been formed from the merger of two white dwarfs. Two sun-like stars have planetary systems: HD 134060 has two small planets, and HD 129445 has a Jupiter-like planet. Supernova SN 185 appeared in Circinus in 185 AD and was recorded by Chinese observers. Two novae have been observed more recently, in the 20th century.

- David Hume (plato.standford.edu)
Generally regarded as one of the most important philosophers to write in English, David Hume (1711–1776) was also well known in his own time as an historian and essayist. A master stylist in any genre, his major philosophical works—A Treatise of Human Nature (1739–1740), the Enquiries concerning Human Understanding (1748) and concerning the Principles of Morals (1751), as well as his posthumously published Dialogues concerning Natural Religion (1779)—remain widely and deeply influential.
