The church was begun in 1511. Henry Trecarell, of Trecarell, in Lezant, was rebuilding his mansion there in great splendour. He had already constructed a chapel and a noble banqueting hall, and had got masses of carved granite ready for a gateway, when his only son, a child, was drowned in a basin of water whilst the nurse was bathing him, she having left him for a few moments. The mother survived the shock only a few hours. Henry Trecarell, the father, dropped for ever the intended mansion for himself, and devoted his wealth to a higher ambition--the glory of God. He rebuilt not only the church of Linkinhorne, but also that of Launceston. On the south porch of the latter on a shield appear the Trecarell arms, arg. two chevrons _sable_, which are those of Ashe of Devon, Trecarell being really an Ashe, but he bore the name of his Cornish residence. On a scroll is the date 1511. The niche over the door has lost its image, but on the left are S. George and the dragon, and on the right S. Martin dividing his cloak with a beggar. Above S. George is the Good Samaritan, and above S. Martin is Balaam striking his ass. At the east end of the chancel, externally in the central gable, are the royal arms, the supporters of which are the lion and red dragon (the unicorn was substituted for the dragon by James I. in 1603). Under the sill of this window, in an arched recess, is a recumbent figure of the Magdalen. Four surpliced minstrels are on each side of the niche, and above the line of the niche similar figures ascend in pairs, but those in the two topmost storeys seem never to have been completed. The instruments which these musicians hold are the rebec, the lute, the bagpipe, shawm, and harps, and one plays the viol, turning a handle like a hurdy-gurdy. The leader of each set of minstrels carries a _bâton_, and wears a chain about his neck. The devices carved round the church are repetitions of the plumes of the Prince of Wales, pomegranates, balm-plants dropping precious gums, the Tudor rose, and the arms of Trecarell, Kellaway (three pears), and the castle of Dunheved. Above the plinth encircling the building is a line of panelled tracery. In every alternate panel is a shield, bearing a letter, that make up the words: “Ave Maria, gracia plena! Dominus tecum! Sponsus amat sponsum. Maria optimam partem elegit. O quam terribilis ac metuendus est locus iste! Vere aliud non est hic nisi domus Dei et porta celi” (“Hail, Mary, full of grace! The Lord be with thee! The bridegroom loves the bride. Mary hath chosen the best part. Oh, how terrible and fearful is this place! Truly this is no other than the house of God and the gate of heaven”).
