Question: Pomponius Grekeinos was commemorated by an inscription on what underground burial places?

The New York City Marble Cemetery is a historic cemetery founded in 1831, and located at 52-74 East 2nd Street between First and Second Avenues in the East Village neighborhood of Manhattan, New York City.  The cemetery has 258 underground burial vaults constructed of Tuckahoe marble on the site. <SEP> Pomponius Grekeinos was a Christian of the early 3rd century who is commemorated by an inscription in the Catacombs of Rome. <SEP> The historic region of Syria (Hieroglyphic Luwian: "Sura/i"; ; in modern literature called Greater Syria, Syria-Palestine, or the Levant) is an area located east of the Mediterranean sea.  The oldest attestation of the name Syria is from the 8th century BC in a bilingual inscription in Hieroglyphic Luwian and Phoenician.  In this inscription the Luwian word "Sura/i" was translated to Phoenician "ʔšr" "Assyria."  For Herodotus in the 5th century BC, Syria extended as far north as the Halys river and as far south as Arabia and Egypt.  For Pliny the Elder and Pomponius Mela, Syria covered the entire Fertile Crescent.  In Late Antiquity Syria meant a region located to the East of the Mediterranean Sea, West of the Euphrates River, North of the Arabian Desert and South of the Taurus Mountains, thereby including modern Syria, Lebanon, Jordan, Israel, the State of Palestine and parts of Southern Turkey namely the Hatay Province and the Western half of the Southeastern Anatolia Region.  This late definition is equivalent to the region known in Classical Arabic by the name "ash-Shām " الشام /ʔaʃ-ʃaːm/ , which means "the north [country]" (from the root "šʔm " شأم "left, north").  After the Islamic conquest of Byzantine Syria in the 7th century AD, the name "Syria" fell out of primary use in the region itself, being superseded by the Arabic equivalent "Shām", but survived in its original sense in Byzantine and Western European usage, and in Syriac Christian literature.  In the 19th century the name Syria was revived in its modem Arabic form to denote the whole of Bilad al-Sham, either as "Suriyah" or the modern form "Suriyya", which eventually replaced the Arabic name of Bilad al-Sham.  After World War I, the name Syria was applied to the French Mandate for Syria and the Lebanon and the contemporaneous but short-lived Arab Kingdom of Syria. <SEP>  Though most famous for Christian burials, either in separate catacombs or mixed together, people of all the Roman religions are buried in them, beginning in the 2nd century AD, mainly as a response to overcrowding and shortage of land.  The Etruscans, like many other European peoples, used to bury their dead in underground chambers.  The original Roman custom was cremation, after which the burnt remains were kept in a pot, ash-chest or urn, often in a columbarium.  From about the 2nd century AD, inhumation (burial of unburnt remains) became more fashionable, in graves or sarcophagi, often elaborately carved, for those who could afford them. The Catacombs of Rome (Italian: "Catacombe di Roma" ) are ancient catacombs, underground burial places under Rome, Italy, of which there are at least forty, some discovered only in recent decades.  Christians also preferred burial to cremation because of their belief in bodily resurrection at the Second Coming.
