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 early 5th 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. Both the sarcophagus and Tabnit's decomposed skeleton are now in the Istanbul Archaeology Museums.
^Torrey 1902, pp. 168–9 (footnote): "When the sarcophagus of Tabnit was exhumed, in the year 1887, and the lid was removed, the body of the king was found to be in a very good state of preservation. It was lying in a brownish-colored, somewhat "oily" fluid, which nearly filled the sarcophagus. The eyes were gone; the nose, lips, and the most prominent part of the thorax, which had not been covered by the liquid, had decayed away; in other respects, however, the corpse was like that of a man only recently buried. It was but slightly emaciated; plenty of flesh remained on both face and limbs, and the skin was soft to the touch. The vital organs and viscera had not been removed (a note-worthy circumstance), and were perfectly preserved. Dr. Shibly Abela, of Sidon, a physician of education and experience, remarked that the face showed traces of small-pox; it was not apparent, however, that the king had died of that disease. The color of the skin was described as somewhat "coppery," the tinge being perhaps due to the influence of some substance, or substances, held in solution by the enveloping fluid. The fluid itself may have been partly, or even wholly, rain-water, which finds its way into most of the tombs about Sidon; but in any case it is evident, from the facts just given, that the body of the king had been skilfully embalmed. I do not know that any similar case has ever been observed and reported. After the body had been removed from the sarcophagus and exposed to the sun. it decomposed and shrunk to withered skin and bones in a very short time. My chief authority for these facts is the Rev. William K. Eddy, of Sidon, a keen observer and cautious reporter, who was one of the few who saw and touched the body of Tabnit when it was first exposed to view. Mr. Eddy was positive in his opinion that the king, at the time of his death, had not passed middle life; the face, he thought, was that of a man of less than fifty years of age."
