	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 for the twelve hours of the night. These constellations shift successively, so that the Egyptian schema needs to be read diagonally: every ten days, another constellation is considered to rule the same hour, or in other words, each constellation (decan) rules a different hour depending on the time of the year.

			River boats are frequently depicted in Egyptian art. They were used for rituals where statues of gods were moved in processions (on boats), while the cheering people could watch them passing by from the shores of the Nile river.

In any case, as a rough estimate, the middle of [[Sagittarius]], where the teapot is usually seen, seems to be consensus.

	The name was suggested to WGSN in 2025. Wia is a huge Egyptian constellation as Reret of Nekhet, spreading from Scorpius to Sagittarius, so I do not ~~see~~ appropriate to name a single star after it. Much more appropriate might be Hery-ib-Wia ("In the Middle of the Boat") if we find a star close to [[Kaus Australis]] without a name (see Fig 4.1 and Table 4.5 in Belmonte and Lull, 2023, for ideas). In case of this name, Lull, Belmonte, and Leitz agree that it must be in Sagittarius.		The name was suggested to WGSN in 2025.
