Input: Passage: Gasquet (1908) claimed that the Latin name atra mors (Black Death) for the 14th-century epidemic first appeared in modern times in 1631 in a book on Danish history by J.I. Pontanus: "Vulgo & ab effectu atram mortem vocatibant. ("Commonly and from its effects, they called it the black death"). The name spread through Scandinavia and then Germany, gradually becoming attached to the mid 14th-century epidemic as a proper name. In England, it was not until 1823 that the medieval epidemic was first called the Black Death.
