He is clearly wrong in stating that Luis de Leon was set free on December 23. We have already seen that Luis de Leon presented two applications in writing on December 15. From the nature of these applications, it is a fair inference that he was free when he made them.
Especially as the fact is confirmed by a contemporary Augustinian, Fray Juan Quijano: see Blanco García, op. cit., p. 206, n. 1.
This date is given on the authority of the anonymous writer quoted by Gallardo, op. cit., col. 1328: 'Y lunes adelante le presentó el Comisorio al Claustro, para que se le diese su proprio lugar, honra y cátedra de Durando. Él no la quiso y la Universidad cedió 200 ducados de partido.' The date in this case is corroborated by a summons from the Rector of the University: see P. Fr. Luis G. Alonso Getino, O.P., Vida y procesos del maestro Fr. Luis de León (Salamanca, 1907), p. 244.
According to Blanco García (op. cit., p. 207), Luis de Leon did not vote, but assigned his proxy to Bartolomé de Medina. This incident occurred, but it happened at a meeting of the Claustro held two days later: see Alonso Getino (op. cit., pp. 252-254). Medina seems to have thought that Luis de Leon's chair had not been legally vacated, and that it was not in Luis de Leon's power to say that he would assign it to Castillo.
