Heptameter

Heptameter is a type of meter where each line of verse contains seven metrical feet. It was used frequently in Classical prosody, and in English, the line was used frequently in narrative poetry since the Romantics. The meter is also called septenary, and this is the most common form for medieval Latin and vernacular verse, including the Ormulum. Its first use in English is possibly the Poema Morale of the twelfth/thirteenth century.
