xistercian allows you to use Cistercian numerals in LaTeX. The glyphs are created using PGF and to a certain degree configurable. You can use Cistercian numerals as page numbers using \pagenumbering{cistercian}. The two main macros are: \cistercian{<counter>}, which formats the LaTeX2e counter as a Cistercian numeral, and \cisterciannum{<integer>}, formats the integer (given as a string) as a Cistercian numeral.
