He is well known from his sarcophagus, decorated with two separate and unrelated inscriptions – one in Egyptian hieroglyphics and one in Phoenician script.

It was created in the 6th century BC, and was unearthed in 1887 by Osman Hamdi Bey at the Ayaa Necropolis near Sidon together with the Alexander Sarcophagus and other related sarcophagi.

Tabnit's body was found floating in the original embalming fluid and almost perfectly preserved, save for the face and neck which were not submerged, but Bey's men spilled all the fluid and left the body to rot in the desert sun, at which point it quickly decomposed to little more than bones and withered viscera.

[2][3] Both the sarcophagus and Tabnit's decomposed skeleton are now in the Istanbul Archaeology Museums.

[6] This is partially due to their resemblance to similar sarcophagi such as the Psamtik II-era Horkhebit sarcophagus from Saqqara, now in the Metropolitan Museum of Art.
