An overdeveloped mount carries with it an unhealthy and over-exercised desire for sensual activities, be they of eating, drinking, or venereal congress. A greatly swollen mount of Venus that is red in hue is a very bad sign, as the bearer will be consumed with a violent passion for the opposite sex(64). This is modified, however, by the location of the overdevelopment. If it be puffy near the thumb, the individual is ruled by emotions; when located lower down on the mount, the bearer is self-indulgent and egocentric in their pursuits. Naturally, both attributes will be present if both areas are puffy.

If underdeveloped, the mount tells of a lack of energy, a poor resistance to disease, and dark pessimism. Though the bearer of such a mount is capable of love, it will manifest itself mentally rather than physically(90). If the mount isn't necessarily flat but narrow, the owner demonstrates a cautious nature.

Marks:

• Horizontal lines on the mount that cross the line of life are lines of influence that typically weaken the mount, and will be covered under the said line.
• Vertical lines, in moderation, add vigor to and foritfy the mount. Two or three lines may bring out the most stellar qualities of the mount, or make up for excesses or deficiencies in overdeveloped and underdeveloped mounts, respectively. Any markings exceeding this quantity, however, will once again exacerbate the evil qualities of the mount.
• A grid on the mount represents a cancellation of the positive aspects of the vertical versus the negative aspects of the horizontal lines.
• A cross on the mount of Venus is particularly negative, and denotes an insatiable and violent passion for the opposite sex if on an overdeveloped mount. There is one exception to this rule, however: if the cross be very large and distinct, it represents an only love, typically of a tragic nature(118)(173).
• A star portends the death of a friend or relative(118).
• Though a square typically is a symbol of preservation, when it is lower down and close to the line of life on the mount of Venus it overextends itself in meaning, as it is a symbol of incarceration, hermitude or life in a convent(119). If it is not in that position, it is a benevolent sign of protection and cancellation of the poor qualities of the mount.
• A spot serves to besmirch the good qualities of the mark with disease related to carnal embrace. If the spot be very dark, it is most likely a venereal disease(118). A lighter spot may very well relate to some brain fever or ulcerous malady brought upon by tragedy in a love affair.
• A circle on the mount betokens chronic ill-health119.
