The first syllable of the name Rasalgethi also appears in the names of two other prominent stars that are at their highest at almost exactly the same time as Rasalgethi: Rastaban (Beta Draconis in the head of the Dragon) and Rasalhague (Alpha Ophiuchi in the head of the Serpent-Bearer).
Path was from alpha Ophiuchi, passed 109 Herculis and toward alpha Lyrae (15[degrees] to 20[degrees]).
Some 25[degrees] to their east (left in the Northern Hemisphere) is Rasalhague (Alpha Ophiuchi), the brightest star in its sector of sky by a fair margin.
Alpha Ophiuchi, a brighter star just 5[degrees] from Rasalgethi, is "Rasalhague"--Arabic for "Head of the Serpent-Holder." (Notice the similarities of Semitic languages: the Jewish New Year is Rosh Hashanah, "head of the year.")
