Allusion can be defined as a literary device in which an object, person or event from unrelated context is referred to, either directly or by implication. This literary device is based on the assumption that there is common knowlegde between the writer and the reader, so that the last one would understand the reference. Within this list, the example of allusion is:
Well, in that hit you miss: she'll not be hit, With Cupid's arrow; she hath Dian's wit.
