	<gallery>		Decan star clocks (also "diagonal star clocks") represent one of the earliest known systematic methods of stellar timekeeping, as they are preserved from the Middle Kingdom (2100-1800 BCE). During the night, the successive appearance of decans provided a way to divide the night into approximately '''twelve parts'''.

			Bawy can be considered as a syncretism of Set and Heru. Then, the name Harwyfy can also refer to them, it translates to "He with the Two Faces".

Note: On the circular Dendera zodiac, there is an unexplained couple of deities in Cetus. They carry planet symbols but are south of the region where planets orbit. These unexplained deities are unlikely to be related to Bawy.

mnemonic tales and cultural significance

== IAU Working Group on Star Names ==
In 2023, it was suggested to WGSN to use a star in Cetus to commemorate this obsolete constellation.
