Romae, via Ardeatina, natalis sanctorum Martyrum Marci et Marcelliani fratrum, qui, in persecutione Diocletiani, a Judice Fabiano tenti et ad stipitem alligati, in pedibus clavos acutos acceperunt; cumque non cessarent laudare Christum, lanceis per latera transfixi sunt, et cum gloria martyrii ad siderea regna migrarunt.
