Kenmon Shokamon (見聞諸家紋)

Kenmon Shokamon (見聞諸家紋; also called Higashiyama-dono Gomonchō), c. 1467–1470. Muromachi album of drawings of warrior-house marks observed on banners and camp curtains. Motif type-names on the drawings are later catalogue labels, not Muromachi captions written with the original plates. (National Diet Library (later transcript))

Supports: Supports that Kenmon already draws both go-san and go-shichi kiri, plus oni-kiri and enclosed versus open forms, as separate drawings rather than one named mark.

Mōko Shūrai Ekotoba (蒙古襲来絵詞)

Mōko Shūrai Ekotoba (蒙古襲来絵詞), illustrated scroll of the 1274 Mongol invasion; surviving recension late thirteenth century. Paulownia appears as a military flag charge without go-san or go-shichi labels.

Supports: Supports unlabeled paulownia as a late-thirteenth-century military charge; does not identify those flags as the named go-san 3-5-3 type.
