"For the Arms - Azure: a chevron betwixt three coaches or ,For their Crest upon a wreath of their colours, a Phoebus in his glory sitting in his chariot or, And for the Supporters: two horses argent, bridled and harnessed sable, the harness studded or garnished gules, and housed azure, with fringe and purfling or adorned with plumes of feathers; or, azure, argent and gules. And this Motto at the bottom of the Shield - Surgit Post Nublia Phoebus - And for their Common Seal, a chevron betwixt three coaches with the circumscription, Sigillum Commune Societatis Opificum Rhedarum et Stratorum London."
Bromley and Child in their book The Armorial Bearings of the Guilds of London state: "In spite of the obvious classical allusion in the Blazon, the motto itself appears to have no earlier traceable origin than a medieval Latin proverb dating from about the 12th century". The literal translation of the motto is "He will rise up after the cloud of Phoebusand the sense of the literal translation is It will rise up like the cloud of Apollo"
However, Elvin in his Book of Mottoes 1860 translates the motto as: THE SUN RISES AFTER THE CLOUDS and he attributes it both to the Coachmaker company and the family of Constable who were Baronets until the title became extinct in 1746. Similarly, Fairbairn in his book Fairbairns Crests translates the motto as: AFTER CLOUDS RISES THE SUN.
