Died c. 640. Tysilio, a Welsh prince, became abbot of Meifod in
Montgomeryshire, where his cultus is centred. Nearby is a town named
for him, Llandysilio. He founded several churches in the other parts of
Wales, including Clwyd, southwest Cardiganshire, Menai Straits, and
near Dyfed. Finally, around 617, he may have migrated to Brittany and
died at Saint-Suliac, although this may be a different saint for whom a
Welsh origin is claimed
(
Benedictines,
Bowen,
Doble,
Farmer).
Troparion of St Tysilio
Tone 8
Princely dignity was set at nought by thee, O Father Tysilio,
for thou didst put aside the glory of this world preferring to serve God in
monastic poverty.
Wherefore we pray thee, intercede for us, that with
courage we may renounce mammon
and live only in Christ for the salvation of men's souls.
