[NTG-context] TYPE 1 font

I have a pfb and tfm file of the DANTE font, which has only the five characters D,A,N,T,E However, this did not work \definefont[dante][dante at 16pt] \starttext \dante DANTE \stoptext When I create a afm file from the dante.pfb then everything is fine. Does ConTeXt always needs an afm-file for the metrics of an type 1 font? And, of course, a map file? Herbert
