Constellation Ivory Tower (prigtxeklÌw.)
The Ivory Tower, in which time and space are said to be interwoven and the past is illusory, was named by early European explorers who sailed the southern oceans, along with the Bridge, the Elephant, the Flamingo, the Hummingbird, the Jaguar, the Kangaroo, the Loom and Shuttle, the Seal, the Shark, and the Thimble.
It is located to the south of the Centaur. Its base corresponds to our constellation Musca (the fruit fly), while its top is at the northeastern end of the constellation at the star ζ Arae. In the top half of the tower, β Trianguli Australis is a fine man playing the timpani while looking out of a window; it is accordingly known as podaRèg. ‘the timpanist’.

The 109 naked-eye stars
In the ‘Our designation’ column, letters (sometimes with superscript numbers) in front of constellation symbols refer to Bayer’s catalogue or to variable star designations, and numbers to Flamsteed’s catalogue. Row colours roughly approximate the stars’ colours. The links lead to the stars’ entries in the SIMBAD Astronomical Database.
