LONDON — First, the archaeologist and her team uncovered a sarcophagus from a village in southern Greece in 1984.

Thirty-four years later, an ancient road in the same village led to a Roman mausoleum.

Then, in October, a lost city called Tenea was found.

“After I uncovered the sarcophagus, I knew I had to go back for more,” the archaeologist, Elena Korka, said in a telephone interview on Friday.

Dr. Korka, the director of the Office for Supervision of Antiquaries and Private Archaeological Collections in Greece’s Ministry of Culture, started the current project in 2013. But excavations in Chiliomodi, the small village where her team found the sarcophagus in the Peloponnese Peninsula south of Athens, did not begin until early September this year.
