The marine facies of the later Tertiaries is confined to the neighbourhood of the coast, and was probably formed after the elevation of the Andes; but inland, freshwater deposits of this period are met with, especially in Patagonia.
The Lower Tertiaries are represented by three different formations known as the Thanet beds, the Woolwich and Reading beds, and the Oldhaven and Blackheath beds.
The middle series of the Lower Tertiaries, known as the Woolwich and Reading beds, rests either on the Thanet beds or on chalk, and consists chiefly of irregular alternations of clay and sand of very various colours, the former often containing estuarine and oyster shells and the latter flint pebbles.
The highest and most local series of the Lower Tertiaries is the Oldhaven and Blackheath beds lying between the London Clay and the Woolwich beds.
The question has been hotly debated whether, in addition to these six grades, there be not a seventh answering in some degree to the tertiaries of the Franciscan and Dominican orders, but secretly affiliated to the Society and acting as its emissaries in various lay positions.
In the European Miocene Listriodon, which also occurs in the Indian Tertiaries, the molars have a pair of transverse ridges, like those of the proboscidean Dinotherium; but the genus is believed to be related to the Oligocene Doliochoerus and Choerotherium, in which these teeth show a more normal type of structure.
On the Italian side there is usually no zone of folded Tertiaries and the Mesozoic band forms the southern border of the chain.
The Beguine communities were fruitful soil for the missionary enterprise of the friars, and in the course of the 13th century the communities in France, Germany and upper Italy had fallen under the influence of the Dominicans and Franciscans to such an extent that in the Latin-speaking countries the tertiaries of these orders were commonly called beguini and beguinae.
Some of them retained their original character; others fell completely under the dominion of the friars, and were ultimately converted into houses of Dominican, Franciscan or Augustinian tertiaries; others again fell under the influence of the mystic movements of the 13th century, turned in increasing numbers from work to mendicancy (as being nearer the Christ-life), practised the most cruel self-tortures, and lapsed into extravagant heresies that called down upon them the condemnation of popes and councils.'
Their living by weaving and the like, and appear to have been in intimate connexion with the craft-gilds; but under the influence of the mendicant movement of the 13th century these tended to break up, and, though certain of the male beguinages survived or were incorporated as tertiaries in the orders of friars, the name of Beghard became associated with groups of wandering mendicants who made religion a cloak for living on charity; beguigner becoming in the French language of the time synonymous with "to beg," and beghard with "beggar," a word which, according to the latest authorities, was probably imported into England in the 13th century from this source (see Beggar).
Here, too, should be mentioned St Francis's other great creation, the Tertiaries, or devout men and women living in the world, who while continuing their family life and their ordinary avocations, followed a certain rule of life, giving themselves up to more than ordinary prayer and the pursuit of good works, and abstaining from amusements of a worldly kind.
Although something of the kind existed among the Humiliati in the 12th century, the institution of Tertiaries arose out of the Franciscan movement.
At first they were called "Brothers and Sisters of the Order of Penance"; but later on, when the Friars were called the "First Order" and the nuns the "Second Order," the Order of Penance became the "Third Order of St Francis" - whence the name Tertiaries: this threefold division already existed among the Humiliati.
These congregations are the "Regular Tertiaries" as distinguished from the "Secular Tertiaries," who lived in the world, according to the original idea.
The Regular Tertiaries are in the full technical sense "religious," and there have been, and are, many congregations of them, both of men and of women.
There can be little doubt, whatever counter claims may be set up, that the Third Order was one of St Francis' creations, and that his Third Order was the exemplar after which the others were fashioned; but at an early date the other Mendicant Orders formed Third Orders on the same lines, and so there came into being Dominican Tertiaries, and Carmelite, and Augustinian, and Servite, and also Premonstratensian and many others.
These followed the same lines of development as the Franciscan Tertiaries, and for the most part divided into the two branches of regular and secular Tertiaries.
In consequence it is estimated that the number of lay Franciscan Tertiaries now exceeds two millions.
- The most serviceable authority on the Franciscan Tertiaries is probably Max Heimbucher, Orden and Kongregationen (1907), ii.
The same work gives information on the other Tertiaries at the end of the sections on the various Orders.
Against the last great fold which terminates this mountain area northwards are ranged the Tertiaries and recent deposits.
There have also been numerous congregations of Augustinian Tertiaries, both men and women, connected with the order and engaged on charitable works of every kind (see Tertiaries) .
The whole is overlaid unconformably by the younger Tertiaries of Hundes, which are perfectly horizontal and have been quite unaffected by any of the folds.
From the absence of any well-marked unconformity it is evident that in the northern part of the Himalayan belt, at least in the Spiti area, there can have been no post-Archaean folding of any magnitude until after the deposition of the Nummulitic beds, and that the folding was completed before the later Tertiaries of Hundes were laid down.
West of the Blas river a similar reversed fault forms the boundary between the lower Tertiaries and the pre-Tertiary rocks of the Himalaya, while between the Sutlej and the Jumna rivers, where the lower Tertiaries help to form the lower Himalaya, the fault lies between them and the Siwaliks.
But in the eastern and southern counties the Chalk is covered by younger deposits of Tertiary age; the Pliocene Crags of Norfolk and Suffolk, the Lower London Tertiaries (London Clay, Woolwich and Reading Beds, &c.) of the London Basin comprising parts of Essex, Hertfordshire, Middlesex, Bucks and Berks, and northern Kent.
Moreover, besides the various orders of friars, there were the lay Tertiaries that arose and spread far and wide in connexion with the Franciscans and other mendicants, and the similar institute of the Humiliati (see Tertiaries).
