Passage: He first appears in Constantinople in 1401, qualified as an oikeios of the emperor. In 1417 he was possibly sent on a diplomatic mission to the Venetians in the Morea. In 1422 and again in 1429 he was sent by Emperor John VIII Palaiologos as an envoy to the Ottoman Sultan Murad II. At the time he had the relatively lowly rank of protovestiarites, but was quickly promoted to protostrator and then to the senior rank of megas stratopedarches, which he held already during his mission in 1430 to Pope Martin V. During his return from the mission to the Pope, on orders from the Emperor, he raised Thomas Palaiologos to the rank of Despot in the Morea. He led two more missions abroad, one in 1433 to Pope Eugene IV, and one in 1438 to Venice.

question:
Passage: Forman and Bishop William Elphinstone of Aberdeen were the principal envoys who brokered a seven-year truce with King Henry VII of England at Aytoun in September 1497. They were assisted by the Spanish ambassador Pedro de Ayala, who recommended in May 1498 that diplomatic correspondence to Scotland should be copied to Forman, his influential friend. The search for a queen for James began in 1499 when negotiators were appointed to treat with King Henry for the marriage of his eldest daughter, Princess Margaret. Dispensation from the pope for the marriage was received as both James and Margaret were cousins, descended from John Beaufort, Marquess of Dorset. On 8 October 1501, Forman, now postulate to the see of Moray, was commissioned along with Robert Blackadder, Archbishop of Glasgow and Patrick Hepburn, 1st Earl of Bothwell to conclude the treaty of marriage. In that same year, King Henry, in gratitude for his services required that Thomas Savage, Archbishop of York institute Forman as Rector of the parish church of Cottingham. On 26 November 1501, Pope Alexander VI provided Forman to the bishopric of Moray and then only a few months later in 1502, Bishop Forman concluded the Treaty of Perpetual Peace with England at Richmond Palace. The formal proceedings that finally concluded the marriage terms of King James and Margaret Tudor were conducted in Glasgow Cathedral on 10 December 1502 where Forman was a signatory. He was then appointed as a commissioner to oversee the exchange of the ratified marriage treaties at the courts of Henry and James. James designated Forman to conduct Margaret to Scotland but while in England, gave King Henry an undertaking that the King of Scots would not renew the league with France unless Henry was first consulted. The procession to Scotland took them to Fast Castle near Berwick where they stayed with Forman's sister Isabel and her husband Alexander Oliphant of Kellie. In 1509, Forman became commendator of Dryburgh Abbey and tried unsuccessfully to obtain the commendatorship of the wealthy abbey of Kelso in 1511. The lands and possessions of the parson of Boleskin, south of Inverness were given to Forman (as bishop of Moray) in 1511 and then in 1512 he became the Keeper of the castle of Darnaway, near Forres, Chamberlain of Moray and Custumar north of the River Spey.
