English: Anachronistic portrait of John of Gaunt , 1st Duke of Lancaster (1340-1399), Knight of the Garter, fourth but third surviving son of King Edward III of England. Property of his descendant the Duke of Beaufort, hanging at Badminton House , Gloucestershire. Portrait commissioned in about 1593 by Sir w:Edward Hoby (1560-1617) for display inside Queenborough Castle, Kent, probably modelled on Gaunt's now lost tomb effigy in Old St Paul's Cathedral. (Source: Harris, Oliver D. (2010). "'Une tres riche sepulture': the tomb and chantry of John of Gaunt and Blanche of Lancaster in Old St Paul's Cathedral, London", published in Journal of the Church Monuments Society, Vol.25, p.16). (Sir Edward Hoby served from 1597 as Constable of Queenborough Castle in Kent, but had served earlier from 1592 as a Member of Parliament for Kent). Gaunt's tabard shows the royal arms of Castile and Leon impaling his differenced paternal royal arms, while on the Tudor-style shield (circumscribed by the Garter) Castile and Leon is shown as an inescutcheon of pretence, representing his claim to that kingdom by right of his second marriage to Constance of Castile. He is dressed in black armour, as was the custom of his eldest brother the Black Prince. Inscribed in Latin: Johannes filius quartus Edwardi Tertii. Rex Castellae et Legione (sic, Legionis?) Dux Lancastriae Constabularius Caste(llae) de Queensbourg quinto Octobris Anno Regni Edwardi Tertii Anglia(e) 50 ^o Franciae 37 ^o ("John, fourth son of Edward III. King of Castile and of Leon (Castella et Legio), Duke of Lancaster, Constable of the Castle of Queenborough on the fifth of October in the year of the reign of Edward the Third, of England the 50 ^th (i.e. 1376), of France the 37 ^th ").
