# Draw a decorative line thin - thick - thin [duplicate]

Does anybody know how you can draw a line, that starts very thin and then gets thick to the middle and then thin again? I hope this is clear because I cannot produce a minimal example here. I think this should be possible with tikz but any solution / suggestion would be welcome.

I would like to use it to separate the Author from the title on the titlepage.

Three ways with tikz: using the calligraphy library (for pen like strokes), making a very thin losangle and a very thin ellipse.

\documentclass[tikz]{standalone}
\usetikzlibrary{calligraphy}
\begin{document}
\begin{tikzpicture}
\node[minimum size=5cm]{};
\pen (0,0);
\calligraphy (-1,0) -- (1,0);
\fill (-1,-.25) -- ++(1,.1mm) -- ++(1,-.1mm) -- ++(-1,-.1mm) -- cycle;
