מַרְחֶשֶׁת (marcheshet) — acetabulum / deep cooking vessel

Etymology

The word מַרְחֶשֶׁת appears in the Hebrew Bible at Leviticus 2:7 ("מִנְחַת מַרְחֶשֶׁת") alongside the more familiar מַחֲבַת (Leviticus 2:5, "מִנְחָה עַל הַמַּחֲבַת"). Both referred to types of grain-offering (mincha) made with flour and oil. The Hebrew Bible provides no definition of either vessel, and by the time of the Mishna the distinction had already been lost. Tractate Menachot (5:8) asks "What is the difference between a machavat and a marcheshet?" and records two answers: Rabbi Yossi the Galilean said the machavat has no lid while the marcheshet has one; Rabbi Nechemia ben Gamliel said the marcheshet is deep and its contents bubble (from the root ר.ח.ש — to seethe, crawl, bubble), while the machavat is flat and its contents are stiff.

The word's uncertain identity generated a long history of divergent translations. The Septuagint (the Greek translation of the Torah) rendered marcheshet as eskare, a word with many meanings in ancient Greek: hearth, brazier, grill, torch. Jerome's Latin Vulgate used craticula (a grill), and Martin Luther's German Bible followed with Rost (also a grill). The King James Bible went the other way: it translated marcheshet as "frying pan" and machavat as "pan." These Christian translations pointed toward marcheshet as a grilling surface; the medieval Jewish rabbinic tradition understood it as a deep oil-filled pan for frying. The syntactic evidence leans toward the Christian reading — the Bible says "on the machavat" (עַל הַמַּחֲבַת) but "mincha of marcheshet" (מִנְחַת מַרְחֶשֶׁת), with no preposition, suggesting marcheshet may have been a technique rather than a vessel.

In the Haskalah (Jewish Enlightenment) period, writers began assigning these old biblical words new modern meanings. Ben-Yehuda and the Va'ad HaLashon attempted to fix marcheshet as "a deep-sided pan" and machavat as "a shallow pan," but the distinction never caught on; by the 20th century only machavat survived in everyday Hebrew. Marcheshet, however, found new life in medicine. In 1887, the physician Yehuda Leib Katzennelson (pen name: Buki ben Yogli) proposed linking marcheshet to the hip socket (acetabulum), noting that the German word for this anatomical socket, Pfanne (also meaning "pan"), offered a natural calque. In 1935, physician-historian Zissmann Muntner formally proposed "מַרְחֶשֶׁת הַקְּטָלִית" (marcheshet of the hip joint). On 20 May 1942, a committee of four physicians meeting at the Va'ad HaLashon resolved the question: the acetabulum would officially be called מַרְחֶשֶׁת.
