From around early 18th century (actually even somewhat earlier) female goat started to be replaced by a Capricorn (buck goat i.e. male goat) Or with red hooves and horns. The latter was officially adopted and used in official manner by Venetian and Austrian authorities already from late 18th and early-mid 19th century.  -->
