Blacksmith:"For the Constable of Wallingford Castle, see Richard of Wallingford (constable)".Richard of Wallingford (1292–1336) was an English mathematician who made major contributions to astronomy/ astrologyand horologywhile serving as abbotof St Albans Abbeyin Hertfordshire.
Richard was born, the son of a
blacksmith, at Wallingfordin Berkshire(now Oxfordshire) in England. When he was orphaned he was taken to William de Kirkeby the Priorof Holy Trinity Priory. Richard subsequently spent 6 years studying at Oxford Universitybefore becoming a monk at St Albans. He later studied for 9 more years at Oxford. In 1326 he became abbot of St Albans.
Richard of Wallingford is best known for the
astronomical clockhe designed, while he was abbot, which is described in the "Tractatus Horologii Astronomici" (1327). The clock was completed about 20 years after Richard's death by William of Walsham but was apparently destroyed during Henry VIII's reformation and the dissolution of St Albans Abbey in 1539. His clock almost certainly was the most complex clockmechanism in existence at the time in the British isles, and one of the most sophisticated ones anywhere. The only other clocklike mechanism of comparable complexity that is documented in the 14th century is the astrariumby Giovanni de Dondi. Based on the 14th century literary evidence in the 20th century several scholars of horological history have tried to build recreations of Richard of Wallingford's clock. The best known of these for many years was displayed at the Time Museum(now defunct) in Rockford, Illinois; one was built by Eric Watsonand is now in the Wallingford Museum, and one built in 1988 is located at St Albans Cathedral.
Richard also designed and constructed a calculation device, known as an
equatorium, which he called Albion. This could be used for astronomical calculations such as lunar, solar and planetary longitudes and could predict eclipses. This is described in the "Tractatus Albionis". He published other works on trigonometry, celestial coordinates, astrology, and various religious works.
Richard suffered from what was then thought to be
leprosy(although it might have been syphilis, scrofulaor tuberculosis) which he apparently contracted when he went to have his position as abbot of St Albans Abbey confirmed by the Pope at Avignon. He died at St Albans.
Richard of Wallingford, abbot and mathematician is not to be confused with the later Richard of Wallingford, constable of
Wallingford Castle, and supporter of Wat Tylerin the English peasants' revolt of 1381.
