 The constellation is mentioned in the Ramesside Star Clocks and identified by right ascension. Ramesside Star clocks (RSC) are astronomical devices developed in ancient Egypt to measure time by the, most likely, meridian or close to meridian transit of stars.  These hour stars were single stars in a few cases or belong to constellations, some of them very large, of Egyptian sky maps.

 Being imaginative and avoiding interference with the stars in the Ramesside tables, which were probably the brightest in the constellation, we may even suggest for γ Tri a name of something certainly located in the head of Apdu, for example the Eye (the peak is already another hour-star).

The name was adopted for γ Tri (Gamma Trianguli) as proposed.

	~~Gamma~~ Tri is a bright (V=4.0 mag) star of type A0Vn (Abt 1995) at distance of approximately 36 parsecs. [https://ui.adsabs.harvard.edu/abs/2012A%26A...537A.120Z/abstract Zorec & Royer (2012)] estimate the star to have an effective temperature of 9940 K, luminosity of about 32x that of the Sun, radius of 2.11 Rsun, mass 2.26 Msun, projected rotational velocity 254 km/s, and age of 407+-39 million years. Fetherolf+ (2023) detects variability with period 0.450848 day in TESS photometric data, consistent with rotation. Combining the radius calculated from the Zorec ~~data,~~ and adopting the period from Fetherolf ~~as a rotation period~~, this would suggest an equatorial rotation velocity of about 236 km/s, similar to the vsini value. This suggests that the star is seen equator-on. The star also has a dusty debris disk detected by the IRAS, Spitzer, and WISE missions (e.g., [https://ui.adsabs.harvard.edu/abs/2014ApJS..211...25C/abstract Chen et al. 2014, ApJS], 268, 4). All of its properties, including its color, equatorial rotational velocity, and even its dusty debris disk, make the star very similar to Vega, except Vega is seen nearly pole-on, and ~~Gamma~~ Tri is apparently seen nearly equator-on.		γ Tri is a bright (V=4.0 mag) star of type A0Vn (Abt 1995) at distance of approximately 36 parsecs.
