Among those other possibilities, several different tenuous efforts have been made to figure out his birthplace from his appellative name "de Sacrobosco". Long after his death, Johannes de Sacrobosco was called and sometimes is still called by the name John of Holywood or John of Holybush, a name which was constructed by post-hoc reverse translation of the Latin "sacro bosco", where "sacro" is “holy” (sacred), and "bosco" is “wood”. "“Sacrobosco”" as such is an unknown town or region. One traditional report, that he was born in Halifax, West Yorkshire, is the speculation of a 16th-century antiquary, John Leland, which was discredited by William Camden: "Halifax" means “holy hair”, not “holy wood”.
