This working paper examines the historical and intellectual conditions that shaped the modern Western Tarot through a focused study of Robert William Felkin (1853–1926). While Felkin is typically discussed in relation to his later medical and occult activities in London and New Zealand, this paper argues that his formative upbringing in Beeston, Nottinghamshire constituted a distinctive cognitive environment that influenced his approach to symbolic systems. Drawing on the industrial discipline of the Midlands lace trade, the procedural epistemology of Baptist Dissent, and late nineteenth-century psychophysiology, the paper situates Felkin as a custodian rather than an innovator of Tarot. It argues that Felkin’s principal contribution lay in preserving Tarot as an internally consistent classificatory system during periods of institutional fracture within the Hermetic Order of the Golden Dawn. Particular attention is given to Felkin’s role in the preservation of Book T and the Four Colour Scales, understood here as symbolic infrastructure rather than expressive convention. The paper further contrasts Felkin’s custodial orientation with the charismatic and revisionist approach of Aleister Crowley, while explicitly avoiding evaluative or psychologising claims. The study adopts a microhistorical and material-culture methodology and treats Tarot as a symbolic technology shaped by historical systems of constraint, maintenance, and procedural authority. An appendix provides a technical explanation of the Four Colour Scales as a functional classification system. This paper is released as a working paper and may be revised in future versions.
