Oracle bone script: Pictogram (象形) – an alcohol vessel (酉) placed on a mat (一).
In the bronze inscriptions, two strokes (八) were sometimes added above the alcohol vessel, representing overflowing alcohol; this is inherited in the small seal script as 酋. In some bronze inscriptions, two horizontal strokes were sometimes also added below the line representing a mat; the strokes sometimes were changed to something like 八. These two strokes then fused with the mat to give 丌 (a table with two legs) in the small seal script. 丌 later evolved into 大 by process of libian (隸變).
