“Thematic analysis is a process for encoding quantitative information. The encoding requires an explicit "code". This may be a list of themes; a complex model with themes, indicators, and qualifications that are causally related; or something in between these two forms. A theme is a pattern found in the information that at minimum describes and organizes the possible observations and at maximum interprets aspects of the phenomenon. A theme may be identified at the manifest level (directly observable in the information) or at the latent level (underlying the phenomenon). The themes may be initially generated inductively from the raw information or generated deductively from theory or prior research.”

Theodric : A Domestic Tale; and Other Poems (1825), To the Rainbow
Context: p>Methinks, thy jubilee to keep,
The first-made anthem rang
On earth deliver'd from the deep,
And the first poet sang.Nor ever shall the Muse's eye
Unraptured greet thy beam:
Theme of primeval prophecy,
Be still the poet's theme!</p
