The Golden and Rosy Cross, understood in the secret circles ns the Cosmic Cross of the Order, symbolizing universal manifestation, with the manifested Christ in the centre as the power and the grace of all things. The motto is: Ego sum flos campi et lilium convallium. This emblem appears on the title-page of Geheime Figures, issued at Altona in 1785, and is characteristic of the theosophical spirit which permeates the whole work. It was attached evidently to a ribbon or collar, and is probably the reverse side of a Cross shewn in another plate, described as of fine gold and said to have been worn by each Brother on his breast. The inscription on the reverse is the well-known salutation of the Order which was repeated on exposing the symbol: Benedictus Dominus Deus noster qui dedit nobis signum. Beneath this inscription the signs of Mercury, Venus, the Moon, Mars, Jupiter and Saturn are written about a six-pointed star, having the Sun in its centre. (preface)
