| Description: |
- Two vertical declining dials declining 58.1° west and 31.9° east on adjacent sides of the south corner of the Sisters of Charity of Ottawa Mother House. The western dial is approximately 7x8 feet and the eastern dial is approximately 7x4 feet. The dials are of gray plaster with black painted iron gnomons. The dials decline 58.1? west of south and 31.9? east of south. The western dial has hour lines from 10 AM to 7 PM and the eastern dial has hour lines from 7 AM to 3 PM. These dials predate the use of time zones and show local solar time.
Mayall on p. 229; erroneously described this dial as on Mint Tower.
LAMIRANDE, E., Elisabeth Bruyere, Foundress of Sisters of Charity of Ottawa, Ottawa, 1995, p. 207, "In the course of the same winter, Fr. Allard had built a double sundial of great dimension on the southwest angle of the house (corner of Bolton and Sussex streets) which, even today, continues to give the correct time, as it did in Mr. Bruyere's time; she greatly appreciated the convenience. The work presupposed an advanced knowledge of mathematics and astronomy. It was the first of its kind in Canada."
