Mencken slightly mocks a literary group:
"I find it in the deed of a fund given to the American Academy of Arts and Letters to enable the gifted philologs of that sanhedrin “to consider its duty towards the conservation of the English language in its beauty and purity.”

Webster's 1913 Dictionary

Definition: \San"he*drin\, Sanhedrim \San"he*drim\, n. [Heb.
sanhedr[=i]n, fr. Gr. ?; ? with + ? a seat, fr. ? to sit. See
{Sit}.] (Jewish Antiq.)
the great council of the Jews, which consisted of seventy
members, to whom the high priest was added. It had
jurisdiction of religious matters.

When Jesus worked miracles on the Sabbath, complaints were made, and brought to the Sanhedrin, where Caiaphas, the high priest advised that Jesus should die, rather than risk
uprising of the people, which might lead to Roman intervention.

It should perhaps be noted that Sanhedrins were not in fact prorogued by satraps.

Satrap
The title of the ruler of Egypt under the Persians, later adopted under Alexander when he appointed Cleomenes of Naukratis head of the civil administration. The title was then taken for a brief time by Ptolemy I Soter when he became the ruler of Egypt until he took the title of Pharaoh in 305 BC.

Imagine a satrap three hundred years old. He'd be a
po'rogue for sure.

More general than that. Satraps were the equivalent of governors in the Persian empire.

Satraps (Old Persian khšaçapavan): the governors of the satrapies (provinces) of the ancient Achaemenid empire.
The title 'satrap' is older than the Persian empire: the word khšaçapavan is Median (it means 'protector of the realm') and was used to describe the vassal kings of the Median empire. The Median and Persian kings sent out officials with the title "eye of the king" to supervise their satraps.
