Haito (or Hatto or Heito) was a Christian monk and Bishop of Basel.
Haito was born in 763, of a noble family of Swabia. At the age of five
he entered the Abbey of Reichenau, on an island in the Lake of
Constance. Abbot Waldo (786-806) made him head of the monastic school,
and in this capacity he did much for the instruction and classical
training of the monks, as well as for the growth of the library.
When Waldo was transferred to the Abbey of St. Denis, near Paris, in
Haito was made Abbot of Reichenau, and about the same time Bishop
of Basel. He enjoyed the confidence of the emperor
Charlemagne and in
811 was both witness to the emperor's will and was sent with others to
Constantinople on a diplomatic mission, which he fulfilled to the
satisfaction of his master. The interests of his diocese and abbey
were not neglected. He rebuilt the cathedral of
Basel and the abbey
church of Reichenau, and issued appropriate instructions for the
guidance of clergy and people in the ways of religion.
In 823 he resigned both positions, owing to serious infirmities, and
spent the remainder of his life as a simple monk in the monastery of
Reichenau where he died on 17 March 836.
Haito was the author of several works. He wrote an account of his
journey to Constantinople, the Hodoeporicon, of which, however, no
trace has been found so far.
In 824 he wrote the Visio Wettini (P.L., CV, 771 sqq.; Mon. Germ.
Hist.: Poetae Lat. Aev. Car., II, 267 sqq.), in which he relates the
spiritual experiences of Wettin, president of the monastic school of
Reicheneau. The day before his death (4 November 824) Wettin saw in a
vision bad and good spirits; an angel took him through hell,
purgatory, and heaven, and showed him the torments of the sinners and
the joys of the saints. The book, which bears some resemblance to
Dante's Divina Commedia, was soon afterwards put into verse by
Walafrid Strabo (Mon. Germ. Hist., loc. cit.).
While Bishop of Basel, he issued a number of regulations in
twenty-five chapters, known as the Capitulare Haitonis (P.L., CV, 763
sqq., Melon. Germ. Leg., Sect. II, Capitular. Reg. Franc., I, 363
sqq., Mansi, XIV, 393 sqq.), in which he legislated on matters of
diocesan discipline. The statutes were probably published in a synod.
