Definition. An extended metaphor is a comparison between two unlike things that continues throughout a series of sentences in a paragraph or lines in a poem. Also known as a conceit or a megametaphor. Extended metaphor is a common literary device, particularly in poetry. The various elements or images in an extended metaphor may fit together or complement one another in different ways. As David Punter notes, the endpoint of extended metaphorical processes is allegory  (Metaphor, 2007). See Examples and Observations below.
