(Cengilleus, Cingislus, Cynegyslus, or Coengils; also Kengillus, Kemgisel), abbot of Glastonbury A.D. 729-743, succeeding Echfrid, is said to have received for the abbey a grant of land at Polonholt, Torric, and Brunantum from Ethelhard, king of Wessex, and his wife. In conjunction with abbot Ingeld and the presbyter Wietberhtus, he addressed a proposal of mutual intercessory prayer, the first of the kind on record, to the abbot Aldhun and the abbesses Ceuburga and Cenburga, who replied in acceptance of it. His name appears in attestation of a doubtful charter of king Ethelhard, A.D. 737.
