When used in inside \emph, \quote puts the words cited into roman face. Thus,
\starttext
\emph{The \quote{Problemata} in Medieval Times}
\emph{The \quote{\emph{Problemata}} in Medieval Times}
\stoptext
This seems odd. Should \quote not leave the style of the text as it is? That is, should the output of line 1 not look like that of line 2?
