The given lines "If this be error and upon me proved, I never writ, nor no man ever loved" are an example of a/an:

- Quatrain: In poetry, a quatrain is a stanza or a complete poem consisting of four lines. The given lines are a quatrain as they consist of four lines.

- Sonnet: Sonnet is a type of poem that consists of 14 lines, typically written in iambic pentameter and follows a specific rhyme scheme. However, the given lines do not fulfill the structure of a sonnet since they do not follow the rhyming pattern commonly found in sonnets (such as the Shakespearean or Petrarchan sonnet).

- Couplet: A couplet is a pair of two consecutive lines in a poem that usually rhyme and have the same meter. The given lines do not form a couplet as they consist of four lines, not two.

Therefore, the correct answer is that the given lines are an example of a quatrain.
