At a critical juncture or turning point. The place where two roads intersect has had special significance from ancient times. Some tribes used a crossroads as a place for religious sacrifices, and hence they came to be associated with execution. In Christian times, criminals and those who died by their own hand often were buried at a crossroads (since they could not be buried in consecrated ground). Crossroads also were a favorite spot for ambushes, highway robbery, and other nefarious deeds. The phrase “dirty work at the crossroads” crops up throughout the nineteenth century, as well as in a spate of twentieth-century murder mysteries. The idea of a figurative crossroads, a point of having to decide which road to take, is also very old. Erasmus quotes a fragment from the Greek poet Theognis’s Elegies, dating from about 600 b.c., translated as “I stand at the crossroads.”
