In older historiography (e.g. Pius B. Gams, Series episcoporum Ecclesiae catholicae, p. XXII) the death of Cardinal Pelagio is postdated by 10 years (to 1240). The correct date is given by Peter Linehan: The Spanish Church and the Papacy in the 13th Century, Ch. 12 (Spaniards at the Curia), Donovan, p. 115, and Maleczek, p. 169. The latest source adds that on 23 July 1230 the cardinal is referred to as of bone memorie.
