Insert a list into an epigraph environment

Question

I would like to produce the following with a list:

\epigraph{There are only four systems that bridge all linguistic barriers:\\

--The complete set of mathematical symbols,\\

--The International System of Units,\\

--The symbols for chemical elements,\\

--The way of writing notes for music.
}

Answer 1

It works if you add \leavevmode after the end of an \itemize environment:

\documentclass{article}

\usepackage{epigraph}
\usepackage{lipsum}

\begin{document}

\epigraph{There are only four systems that bridge all linguistic barriers:
%
\begin{itemize}
\item The complete set of mathematical symbols,
\item The International System of Units,
\item The symbols for chemical elements,
\item The way of writing notes for music.
\end{itemize}
%
\leavevmode}{}

\lipsum[1]

\end{document}
