Among the bishops that Olaf brought with him from England, was
Grimkell (Grimkillus). He was probably the only one of the missionary bishops who was left in the country at the time of Olaf's death, and he stood behind the
translation and
beatification of Olaf on August 3, 1031.
At this time, local bishops and their people recognized and proclaimed a person a saint, and a formal
canonization procedure through the papal
curia was not customary; in Olaf's case, this did not happen until 1888.
Grimkell was later appointed bishop in the diocese of
Selsey in the south-east of England. This is probably the reason why the earliest traces of a liturgical cult of St Olaf are found in England. An office, or prayer service, for St Olaf is found in the so-called Leofric collectar (c.
1050), which was bequeathed in his last will and testament by bishop Leofric of Exeter to the church of
Exeter, the neighbouring diocese of Selsey. This English cult seems to have been short-lived.
Adam of Bremen, writing around
1070, mentions pilgrimage to the saint's shrine in
Nidaros, but this is the only firm trace we have of a cult of St Olaf in Norway before the middle of the twelfth century. By this time he was also being referred to as "The Eternal King of Norway". In 1152/3, Nidaros was separated from Lund as an archbishopric of its own. It is likely that whatever formal or informal — which, we do not know — veneration of Olav as a saint there may have been in Nidaros prior to this, was emphasised and formalized on this occasion.
During the visit of the papal legate, Nicholas Brekespear (later
Pope Adrian IV), the poem
Geisli ("the ray of sun") was recited. In this poem, we hear for the first time of miracles performed by St Olaf. One of these took place on the day of his death, when a blind man got his eye-sight back again after having rubbed his eyes with hands that were stained with the blood from the saint.
The texts which were used for the liturgical celebration of St Olaf during most of the Middle Ages, were probably compiled or written by Eystein Erlendsson, the second archbishop of Norway (
1161–1189).
The nine miracles reported in
Geisli form the core of the catalogue of miracles in this office.
The celebration of St Olaf was widespread in the Nordic countries. Apart from the early traces of a cult in England, there are only scattered references to him outside of the Nordic area. Several churches in England were dedicated to him (often as
St Olave).
St Olave Hart Street in the
City of London is the burial place of
Samuel Pepys and his wife. Another south of London Bridge gave its name to
Tooley Street and to the
St Olave's Poor Law Union, later to become the
Metropolitan Borough of Bermondsey: its workhouse in
Rotherhithe became the
St Olave's Hospital, now an old-people's home a few hundred metres from
St Olaf's Church, which is the
Norwegian Church in London.
Also it lead to the naming of
St Olave's Grammar School which is consistently one of the top achieving state schools in England, and was established in 1571 and up until 1968 was situated in ""Tooley Street" London where many other things related to St Olaf can be found. In 1968 the school was moved to Orpington, Bromley.
Recently the
pilgrimage route to Nidaros Cathedral, the site of Saint Olav's tomb, has been reinstated. Following the Norwegian spelling the route is known as
Saint Olav's Way. The main route, which is approximately 640 km long, starts in the ancient part of
Oslo and heads North, along
Lake Mjosa, up the
Gudbrandsdal Valley, over
Dovrefjell and down the
Oppdal Valley to end at
Nidaros Cathedral in
Trondheim. There is a Pilgrim's Office in Oslo which gives advice to Pilgrims, and a Pilgrim Centre in Trondheim, under the aegis of the Cathedral, which awards certificates to successful Pilgrims upon the completion of their journey.
The oldest picture of St. Olav is painted on a column in the
Church of the Nativity in Bethlehem.
St Olav's Church is the tallest church in
Tallinn, Estonia and between 1549 and 1625 was the
tallest building in the world.
The Royal Norwegian Order of St. Olav was founded in
1847 by
Oscar I, king of Norway and Sweden, in memory of this king.
St. Olaf College was founded by Norwegian immigrant
Bernt Julius Muus in
Northfield, Minnesota, in 1874.
