hfield, St Martin's-le-Grand and Abergwyly, and the living of
Brington. On the 9th of January 1405 he found time to attend a court at
Higham Ferrers and be admitted to a burgage there. In July 1405
Chicheley began a diplomatic career by a mission to the new Roman pope
Innocent VII., who was professing his desire to end the schism in the
papacy by resignation, if his French rival at Avignon would do likewise.
Next year, on the 5th of October 1406, he was sent with Sir John Cheyne
to Paris to arrange a lasting peace and the marriage of Prince Henry
with the French princess Marie, which was frustrated by her becoming a
nun at Poissy next year. In 1406 renewed efforts were made to stop the
schism, and Chicheley was one of the envoys sent to the new pope Gregory
XII. Here he utilized his opportunities. On the 31st of August 1407 Guy
Mone (he is always so spelt and not Mohun, and was probably from one of
the Hampshire Meons; there was a John Mone of Havant admitted a
Winchester scholar in 1397), bishop of St David's, died, and on the 12th
of October 1407 Chicheley was by the pope provided to the bishopric of
St David's. Another bull the same day gave him the right to hold all his
benefices with the bishopric.

At Siena in July 1408 he and Sir John Cheyne, as English envoys, were
received by Gregory XII. with special honour, and Bishop Repingdon of
Lincoln, ex-Wycliffite, was one of the new batch of cardinals created on
the 18th of September 1408, most of Gregory's cardinals having deserted
him. These, together with Benedict's revolting cardinals, summoned a
general council at Pisa. In November 1408 Chicheley was back at
Westminster, when Henry IV. received the cardinal archbishop of Bordeaux
and determined to support the cardinals at Pisa against both popes. In
January 1409 Chicheley was named with Bishop Hallum of Salisbury and the
prior of Canterbury to represent the Southern Convocation at the
council, which opened on the 25th of March 1409, arriving on the 24th of
April. Obedience was withdrawn from both the existing popes, and on the
26th of June a new pope elected instead of them. Chicheley and the other
envoys were received on their return as saviours of the world; though
the result was summed up by a contemporary as trischism instead of
schism, and the Church as giving three husbands instead of two.
Chicheley now became the subject of a leading case, the court of king's
bench deciding, after arguments reheard in three
