Tadmur) is an ancient Semitic city in present-day Homs Governorate, Syria.Archaeological finds date back to the Neolithic period, and the city was first documented in the early second millennium BC.
The city's social structure was tribal, and its inhabitants spoke Palmyrene (a dialect of Aramaic); Greek was used for commercial and diplomatic purposes.
The culture of Palmyra was influenced by Greco-Roman culture and produced distinctive art and architecture that combined eastern and western traditions.
According to the suggestion by Schultens, "Palmyra" could have arisen as a corruption of "Tadmor", via an unattested form "Talmura", changed to "Palmura" by influence of the Latin word palma (date "palm"), The second view, supported by some philologists, such as Jean Starcky, holds that Palmyra is a translation of "Tadmor" (assuming that it meant palm), which had derived from the Greek word for palm, "Palame".
An alternative suggestion connects the name to the Syriac tedmurtā (ܬܕܡܘܪܬܐ) "miracle", hence tedmurtā "object of wonder", from the root dmr "to wonder"; this possibility was mentioned favourably by Franz Altheim and Ruth Altheim-Stiehl (1973), but rejected by Jean Starcky (1960) and Michael Gawlikowski (1974).
Its destruction by the Timurids in 1400 reduced it to a small village.
Under French Mandatory rule in 1932, the inhabitants were moved into the new village of Tadmur, and the ancient site became available for excavations.The general director of the Czech National Museum, Michal Lukeš, signed an agreement in June 2017 committing the institution to help Syria save, preserve and conserve much of its cultural and historical heritage damaged by war, including the ancient site of Palmyra; he met with Abdulkarim and discussed plans for the works that are said to last until 2019.Italian experts restored the portraits using 3D technology to print resin prosthetics, which were coated with a thick layer of stone dust to blend in with the original stone; the prosthetics were attached to the damaged faces of the busts using strong magnets.The city became a Roman colonia during the third century, leading to the incorporation of Roman governing institutions, before becoming a monarchy in 260.Following its destruction in 273, Palmyra became a minor center under the Byzantines and later empires.The Palmyrenes converted to Christianity during the fourth century and to Islam in the centuries following the conquest by the Rashidun Caliphate, after which the Palmyrene and Greek languages were replaced by Arabic.
